OVERVIEW
Windows NT, the operating system NexSys uses, coordinates the functions performed by the microprocessor to
allow true multi-tasking. You can be working in a spreadsheet, writing a letter in a word processor, and using
NexSys to interface with your building all at the same time. This is an overview of computer basics with
information on the use of Windows NT. Refer to your Windows NT manuals for more information.
NOTE: If you are unfamiliar with Windows NT operations, please see Section XXXX, Windows
NT Help.
The main difference between Windows NT and DOS is multi-tasking. Multi-tasking describes an operating
system that can perform more than one task at a time. With NexSys, multi-tasking is important because it
guarantees that alarms and other critical operations are always given proper attention.
THE COMPUTER
KEYBOARD
There are six types of keys on the keyboard:
Standard keys - These are the keys that correspond to typewriter keys (a, b, 1, 2, SHIFT, TAB, RETURN, etc.).
Use the standard keys to enter and edit text.
Cursor keys - These are the keys to the right of the standard keys. The four arrow keys (Left, Right, Up,
and Down) and the six page keys (Insert, Delete, Home, End, Page Up, and Page Down) are included
in this group.
Keypad keys - These are the keys that correspond to the regular calculator functions (1, 2, 3, +, *, ENTER,
etc.) and are located on the right side of the keyboard.
Function keys - These are special keys located at the top of your keyboard that can be custom defined by
applications. Some applications provide an overlay sheet to remind you of the function key assignments. NexSys has several function keys.
Modifier keys - These are special keys that are used to alter the operation of other keys. The most commonly used are the CTRL (Control) and ALT (Alternate) keys. They are usually held down in a
combination with another key (see the specific application manual for details). The SHIFT and ESC
keys are also frequently used.
Escape key - The ESC (Escape) key is used to abort an application. While in a dialog box, it is the same as
choosing Cancel.
MOUSE
The mouse (Figure 1) is a small hand-held device which allows a user to interface with the computer. The mouse
lets you move an on-screen cursor over the entire screen. The mouse has two buttons, the left and the right.
Buttons
Cable
Roller Ball
Figure 1. Mouse
NOTE: The mouse operates by measuring the rotation of a small rubber roller ball on its bottom
surface. Therefore, the roller ball on the bottom must touching a clean dry surface (the top
of a table or desk, a mouse pad, etc.) for the mouse to work (Figure 2).

BASIC MOUSE ACTIONS
Below is an explanation of the basic mouse actions:
Pointing - Move the mouse until the tip of the cursor rests on a specific item or area. Although the item
may appear highlighted, pointing alone does nothing.
Clicking or Selecting - Point at an item, then press and release the left mouse button. Clicking is used to
select an on-screen item.
Double Clicking - Press and release the left mouse button twice in rapid succession. Double clicking is
used to select an item from a list.
Dragging - Point at an item to be moved, press and hold down either the left or right mouse button, and
then move the mouse (and therefore the cursor-item) to a new location. Release the left or right
button only when the cursor-item is in the correct position.
Swiping (Highlighting) - This is basically the same technique used for dragging, but is used for selecting
text. Point to the left of the first character to include, press and hold down the left mouse button.
Drag the pointer to the right and/or down until the pointer passes the last character to include, then
release the button. Text will appear highlighted.
Right Clicking - Click the right mouse button only. This is used to display the shortcut menu of the item
(folder, window, or icon) that the cursor is positioned on. If no menu exists for that item, none will
be displayed.
CURSOR
The cursor is the on-screen representation of the mouse’s position. When the mouse is moved to the left, the
cursor will move to the left. When the mouse is moved to the right, the cursor will move to the right, and so on.
Typically, the mouse cursor is used to select objects on the screen ( pull-down menus, push buttons, etc.) and to
select text to be edited. In some situations, the shape of the cursor (normally an arrow) will change to show that
the cursor has a different function. Typically, the cursor will be one of the following shapes:
Arrow
- Used for pointing and selecting
Hour Glass
- Used to indicate that you must wait before proceeding
Double Arrows
reflects
Vertical Line
- Used to change the size of a resizable window (The orientation of the arrows
the window dimension being changed.)
- Used to enter text.
Question Mark
- Used to access help on a topic. When this cursor is present, click on an item you
need information on. See Getting Help Inside a Dialog Box for more details.
Cross Hair Pointer
Hour Glass with Arrow
- Used when moving an object.
- Used to show that the computer is working in the background.
NOTE: The cursor may be customized by clicking
Control Panel (
, selecting Settings, and choosing
>Settings>Control Panel). Double click on the Mouse icon.
Click on the Pointers tab and choose the special cursor set you’d like to apply.

SCROLL BARS
When necessary, scroll bars will appear on the bottom and/or left edges of each window, indicating that the
screen size is smaller than the complete display. A Scroll Bar (Figure 3) is a window control that allows you to
view a document larger than the current window. Scroll bars appear along the bottom and/or right edge of the
window. Scroll bars contain three elements:
Scroll Arrows - The rectangular buttons with arrows on them at both ends of a scroll bar
Scroll Box - A solid rectangle between the arrows of the scroll bar. The scroll box indicates how much of
the window is visible by its placement within the scroll bar.
Page Areas - The areas of the scroll bar between the scroll box and each of the scroll arrows.
Figure 3. Scroll Bar
To scroll through a screen one line or one item at a time, click on the appropriate scroll arrows. To scroll
continuously, hold the arrow down. To scroll through the screen one “page” at a time, click on the page area of
the scroll bar. To move more quickly through a window, place the cursor on the scroll box and drag it in the
appropriate direction.
BASIC WINDOW CONCEPTS
The window environment is a rectangular area of the computer screen that applications used to display information. Depending on the application, several windows can be displayed at the same time (Figure 4). Windows can
be opened and closed, minimized, or re-sized according to User needs.

BASIC MENU CONCEPTS
Windows NT uses toolbars, shortcut keys, and toolbar buttons to execute menu commands. It also uses these
tools to access information through dialog boxes, and to manipulate the window environment.
A title bar is located at the top of each window. Below the Title Bar appears the Menu Toolbar. Menu commands
are listed in logical groups. These groups can be located in the menu bar, and are also accessed from within the
application. Both pull-down and pop-up (shortcut) menus are available. A right pointing arrow at the right of a
command indicates a submenu. A submenu contains a list of nested commands for the item you selected.
PULL-DOWN MENUS
One way to access commands is through pull-down menus (Figure 5). Pull down menus are groups of related
commands which are not visible until a menu name is selected. When the User selects the Menu Name, the
pull-down menu of commands is displayed. Click on a command to execute.
Figure 5. Pulldown Menu
NOTE 1: Unavailable menu items will be displayed in gray (or a light shade of the current menutext color).
NOTE 2: If other options exist within a menu, selecting a given menu item may lead to a submenu. Items with submenus are marked with an arrow.
SELECTING A PULL-DOWN MENU
1.
Point to the appropriate menu name.
2.
Click on the menu name. The menu is displayed with the menu name highlighted.
3.
Point to the appropriate menu item. The item will highlight to indicate selection.
4.
Click on the menu item to be selected by pressing once on the left mouse button.
5.
If the selected item has a submenu, repeat steps 3 and 4 for the submenu command.
NOTE: Each menu has a default selection which can be chosen by pressing the Return or Enter
key on the keyboard. The default selection will be the highlighted command. This is also
true for toolbar buttons: the default selection will be the raised button.
EXITING A PULL-DOWN MENU
1.
10
Place the mouse anywhere outside of the menu area and click the left mouse button. The pull-down
menu disappears.

SELECTING A PULL-DOWN MENU (WITH THE CURSOR (ARROW) KEYS)
The pull-down menus can also be accessed through the keyboard in the following manner:
1.
Press the ALT key and the letter key for the appropriate menu name. Each menu name has one letter
underlined (the N in NWS, for example). The underlined letter is the menu’s command letter. The
pull-down menu displays with the menu name highlighted.
2.
Use the arrow keys to highlight the appropriate menu item. Press the up or down arrow keys as
necessary until the appropriate menu item is highlighted. If the appropriate menu item is has a
submenu, press the right arrow key to open the submenu, and repeat this step.
3.
Press the RETURN key to select the menu item.
SELECTING A PULL-DOWN MENU (WITH THE TEXT KEYS)
1.
Press and hold the ALT key. Without releasing the ALT key, press the letter key for the appropriate
menu name. Each menu name has one letter underlined (the N in NWS, for example). The underlined letter is the menu’s command letter. Do not release the ALT key
2.
Press the letter key for the appropriate menu item. Each menu item has one letter underlined (the C
in Close, for example, in Figure 4). The underlined letter is the menu item’s command letter. If the
appropriate menu item leads to a submenu, repeat this step for the submenu.
CANCELING A MENU SELECTION (WITH THE TEXT KEYS)
1.
Press the ESC key. The pull-down menu disappears.
POP-UP (SHORTCUT) MENUS
Pop-up menus (also called shortcut menus) are another way to access commands. Click the right mouse button
on an item to show its pop-up menu (Figure 6). Or, right click an object or window to access the pop-up menu.
If an no pop-up menu exists, none will be displayed.

NOTE 1: Unavailable menu items will be displayed in gray (or a light shade of the current menutext color).
NOTE 2: If other options exist within a menu, selecting a given menu item may lead to a submenu. Items with submenus are marked with an arrow.
SELECTING POP-UP MENUS (WITH TEXT KEYS)
When an item (a folder, icon, etc.) is highlighted, pressing SHIFT-F10 on the keyboard will bring up the pop-up
menu. For example, if the physical tree is running and a node is highlighted, SHIFT-F10 will bring up the popup menu for that node.
NOTE: Press the Escape key to exit the menu.

MOUSE OPERATION IN DIALOG BOXES
Dialog box items (buttons, checkboxes, text fields, text, etc.) display differently when they are selected from
when they are not selected. Below are descriptions and some examples of the appearance change for each
object:
• Buttons - Buttons are “spring loaded” (when the mouse is released, they change back to the normal state).
When clicked on with the mouse, the shading of the button will change slightly and the text of the
button will be outlined with a dashed line:
Not Selected…
or
Selected…
NOTE: The default options will sometimes appear with the dashed outline also.
• Lists - Lists show the selected item as a reversed image (white-on-black instead of black-on-white).
• Menus - A menu selection appears highlighted. Windows NT highlights in blue.
• Radio Buttons - When a radio button is selected a small black dot appears in its center:
Not Selected…
or
Selected…
• Checkboxes - When a check box is selected a small check mark appears in its center:
Not Selected…
or
Selected…
• Fields - A small, vertical flashing bar appears at the left side of a selected empty field:
Not Selected…
or
Selected…
• Page Tabs - A dialog box will often contain several pages inside a single window. Access
each page by clicking on its tab at the top (Figure 8).

·
The NWS LONWORKS® Tool
·
The LNServer
·
LONWORKS® Network Services Architecture
·
The M-Series Workstation
·
OPC LONWORKS® Server
The combination of NWS, M-Series, and OPC technologies provides a full range of facility management setup,
control, and analysis capabilities, all within a LONWORKS®–based environment. Figure 1 below illustrates the
basic architecture.

NexSys Software Overview
NEXSYS WORKSTATION (NWS)
The NexSys Workstation (NWS) is a LONWORKS® tool used for the setup and configuration of the building
automation system. All node configuration, node operations, point binding, and execution of plug-ins is performed with NWS. NWS is also used for writing and editing specialty programs for the Flexible System Controller (FSC) using Control Programming Language (CPL), and scheduling of the FSC.
LNSERVER
LNServer allows NWS to communicate with the LNS architecture. It serves as the interface between NWS and
the LNS Component Object Model (COM) technology. When the user makes a request in NWS, the data is sent
to LNServer using TCP-IP protocol. LNServer then communicates the data to LNS. Information is returned to
NWS and ultimately the user in the same way.
LNS
LONWORKS® Network Services (LNS) 3.0 Architecture is a set of network services that provides inter-operability
between tools. LNS features an Active X “wrapper” that allows it to interface with a variety of applications. LNS
communicates directly with devices on the LONWORKS® network using LONTALK® protocol, and then passes this
information back to the LNServer.
OPC LONWORKS SERVER
The OPC LONWORKS® Server is the “plug-and-play” interface between the M-Series Workstation and the LNS
Architecture. It utilizes Object Linking and Embedding – for Process Control (OPC) technology for plug-andplay software, providing communications between building control systems. The OPC Server accesses data from
the field through LNS, and provides that data to the M-Series Workstation. The OPC LONWORKS® Server is
multi-tasking, and communicates with all LONTALK® media.
M-SERIES WORKSTATION
The M-Series Workstation is the dynamic graphical display for the building control system. The M-Series
Workstation provides trending, graphics, and alarm features to assist users in analyzing system efficiency and
energy consumption. Users can also add navigation links, issue commands, and set up interactive displays of the
facility. M-Series receives information from the field via the OPC Server.

INTRODUCTION
The NexSys Workstation (NWS) PC uses the internally mounted Echelon LonTalk® PCLTA-10, the PCLTA-20, or
the PCC-10:
• The PCLTA -10 (Figure 1) comes with an integrated transceiver
• The PCLTA-20 is available with:
• An integrated transceiver (Figure 2)
• A non-integrated board with the 78K bps Transceiver daughter-board (Figure 3)
• A 1.25Mbps Transceiver daughter-board (Figure 4)
• The 1.25 Mbps Fiber Optic LONWORKS® SMX™ Transceiver daughter-board (Figure 5).
• The PCC-10 (Figure 6) Card is for use with a laptop.
NOTE: Since NexSys 2.0 uses LONWORKS Network Services (LNS), the traditional full-size
PCLTA card with piggyback SMX board may no longer be used.
If you are installing a LonTalk® card for the first time, proceed directly to Installing The
Hardware Drivers. If you have a full-size PCLTA installed, you will need to follow the
procedure Disabling and Removing the Full-Size PCLTA Card on the following page
before you install a new LonTalk® card.

DISABLING AND REMOVING THE FULL-SIZE PCLTA CARD
LNSTM and NexSys 2.0 do not support the full-size PCLTA card. NexSys 2.0 requires a PCLTA-10, PCLTA-20, or a
PCC-10. However, the Echelon PCLTA driver install program used with NexSys 1.33 and all previous Windows
NT versions of NexSys does not have an uninstall feature. In order to install an LNS compatible card, you must
first disable and then physically remove the PCLTA driver from the NT system.
1.
Open the Windows NT Control Panel by pressing
>Settings>Control Panel. Double click
on the Devices icon. The Devices window displays (Figure 7).

INSTALLING THE HARDWARE DRIVERS
The PCLTA-10 is a half-size ISA card for a standard PC. The PCLTA- 20 is the PCI version of the card for a
standard PC, and it comes in two varieties; with an integrated transceiver board, or with a piggyback mounted
SMX board.
The PCC-10 is a PCMCIA card for a laptop computer and is equivalent to a PCLTA-10/20 card in a desktop
computer.
No matter which card you use , you will follow the same installation procedure. This is a general guideline for
installing the PCLTA-10/PCLTA-20 or PCC-10 card under Windows NT. To install the driver, you will need the
driver and install files located on your NexSys Install CD in the Pclta10 folder.
1.
Start up Windows NT. Do NOT install the hardware first, as Echelon recommends that you run the
install program prior to installing the card. Place the NexSys Installation CD-ROM into your CDROM drive.

START-UP PROCEDURE
NexSys Workstation (NWS) is always run concurrently with LNServer. NWS needs LNServer to communicate
with LNS and ultimately, the devices in the field.
All remote NexSys systems need the LNServer on the main system to be running so that they can communicate
with the network. In accordance with this requirement, the User can open both programs with one command, but
each program must be shut down separately.
NOTE: This chapter gives general information on start-up procedures only. For detailed information on NWS functions, see Section Five, Operations - Chapter One.
ADD ESUSA RESOURCES TO CATALOG
After the NWS installation has been completed but before starting NWS and LNServer for the first time, the
User must first add NWS Resources Files to the LNS Catalog.
ESUSA Resource Files are files that contain the manufacturer-specific information on how to properly display
data on NWS. All additional information on NVs, CPs, and documentation is contained in the files. The Echelon
LONMARK Support Catalog is a software tool that allows NWS and LNS easy access to these files.
NOTE: The User must add the Resources Files when starting NWS and LNServer for the first
time only. Should the User at a later date receive new or updated Resources Files from a
manufacturer, follow the same procedure that is explained below.
ADDING ESUSA RESOURCES TO CATALOG
1.
Click
> Programs > NexSys 2.0 Main (Remote) System > Add ESUSA Resources to
Catalog (Figure 1).
2.
The LONMARK Device Resource Files Editor (Figure 2) opens. Click

RESIZING THE NEXSYS WINDOWS
To make a window smaller or larger:
1.
Place the cursor on either a horizontal or vertical window border. When the double
ended arrow appears, drag the edge or corner of the window to resize appropriately.
2.
Dragging the edge of a window will change only one dimension of the window.
To change both the width and the height of the window equally, drag a corner of the window.
If you resize a NexSys window, the workstation will remember. When the resized window is reopened, it will
retain the new dimensions. Use caution when resizing windows. By making a window smaller, you may
eliminate important information fields (check boxes, radio buttons, text fields, etc.) from the visible part of the
window. Use the scroll bars to view the “hidden” part of the screen, or resize the window to show all the fields.
MENU BAR
The Menu Bar (Figure 15) contains the names of NWS menus. It appears below the Title Bar. Each menu item is
a pull-down list of available commands. You open a menu by clicking on the menu name. Figure 16 below
shows an example of an NWS Menu Bar pull-down menu.

OVERVIEW
There are common node functions used in the NexSys Workstation. For example, the same process is used for
winking a Flexible System Controller (FSC), Fan Coil Unit (FCU), Heat Pump Unit (HPU), Package Equipment
Controller (PEC), Rooftop Unit (RTU), and a Variable Air Volume controller (VAV-01, and VAV-02). These
commonalties can be loosely categorized as node information accessible from the Physical Tree window,
features of the Node Configuration wizard, and node commands.
NODE MENU
The Node Menu (Figure 1) is used to setup nodes and their functions. There are thirteen menu choices on the
Node Menu that help you to configure your system. The following thirteen menus, several of which have
submenus, explain these functions.
NODE COMMANDS
There are four commands available in the Node Commands Menu: Wink, Offline, Reset, and Test. The Node
Commands Menu (Figure 2) is shown below.
Figure 1. Node Menu
Figure 2. Node Commands Menu
WINK
Issuing a Wink command from the Node Commands Menu identifies the selected node in the field. Most devices
flash the Wink LED on that node. However, since Wink tasks are device specific, some 3rd party devices may
include such actions as the flashing of an LED, or sounding of an alarm.
Note: Winking the FSC lights LEDs 1-8 on the 386 CPU.
To Wink a node:
1.
Right click on the node’s icon. The Node Menu appears.
2.
Right click on the Node Commands Menu, the submenu appears (Figure 2).
3.
Click on Wink. The selected node’s Wink LED flashes, the Node Command submenu (Figure 3)
appears and displays “Finished” in the bottom left corner.

button to close the Node Command submenu.
TEST
Issuing the Test command from the Node Commands Menu the tests the selected application device or router.
Testing an application device verifies that the device is able to communicate on the network and that its configuration matches the information contained in the LNS database. To pass the test, an application device with the
expected Neuron ID must exist on the network, contain the expected domain/subnet/node address (if the device
is installed), contain the expected program ID, contain the expected network management authentication setting
(enabled or disabled), and, if network management is enabled, contain the correct system authentication key.
Testing a router verifies the router is able to communicate on the network and that its configuration matches the
information contained in the LNS database. To pass the test, a router with the expected Neuron IDs must exist
on the network, contain the expected domain/subnet/node address (if the router is installed), and contain the
expected program ID.
The Test command assumes that the node's network image is up-to-date. Be sure that the node is up-to-date by
running the Test command only while LNServer is in the OnNet mode.
To Test a node:
NOTE: A PEC is used in the following example.
1.
Right click on the PEC icon. The Node Menu appears (Figure 9).

SETUP NODE
After a node has been added, it must be setup to be functional. This process is called commissioning. After the
node had been setup it will be functional, but will have default configuration settings. It is suggested that you run
the Configuration Wizard to properly configure the node. Any node that has not yet been commissioned will
have (Never Commissioned) after the device’s name on the tree.
Note: A PEC is used in this example.

If you know the exact Neuron ID for the PEC, type it in the Neuron ID field. The Neuron ID is
specific to the PEC controller you are setting up and is given to the NexSys Workstation when the
service pin is pressed on the controller. If you do not know the exact Neuron ID number, do not type
anything in this field. Go to Step 3.
3.
If you don’t know the Neuron ID then click the Service Pin button on the Node Setup menu. Next
press the Service Pin on the PEC you are commissioning. This registers the Neuron ID, Program ID
and associated device specific information. Once you press the service pin on the PEC the Setup
Node Menu displays the PEC’s Neuron ID and Program ID information (Figure 24).

The checkboxes on Figures 24, 25, and 26 are described in the next paragraph.
CHECK BOX EXPLANATIONS
The node setup pages contain a number of checkboxes that are used in the configuration process. Their settings
determine the information sent and whether it is sent from the LNS database to the device, or vice-versa.
Choose carefully how you use these commands. If used incorrectly, it is possible to overwrite default values that
are not recoverable.
NOTE:
SEND moves data from the LNS database to the device.
GET moves data from the device to the LNS database.
Send Network Image - Sends the device’s network address and bindings to the LNS database.
Send Config. Data - Sends the device’s configuration parameters (CPs) from the LNS database to the device.
Force Defaults - Sends the default CPs from the LNS database to the device.
Send Trend - Sends Trend setup data from the LNS database to the device.
Get Config. Data - Gets the device’s CPs from the device and sends them to the LNS database. This is used as a
backup in the event the device requires reconfiguration.
Use as defaults - Checking this box gets the device’s current configuration settings and makes them the
default CP settings for all similar devices. These settings are stored in the LNS database.
Note: Use this command when you have a number of devices that will be configured the same.
Get unknown only - Gets any “unknown” CP data, from the device currently being setup, and sends it to
the LNS database. Typically, unknown CP information is associated with 3rd party devices.
Get Trend - Gets Trend setup data from the device and sends it to the LNS database.
Close window when configuring node done - Closes the configuration window and displays the tree as soon as
the configuration process is done.

cancel you will be prompted to confirm your cancellation. Confirming the cancellation closes the
wizard and returns to the tree display. Abandoning the cancellation returns you to the wizard.
REPLACE NODE
The Replace Node command is used when a defective node device, such as a PEC, must be replaced. Since each
node has a unique Neuron ID, simply replacing the device without using the Replace Node command will cause
errors. The defective device must be replaced with the exact same device type. Example: You cannot replace a
VAV-01 with a VAV-02 since they have different Program ID types. You must either replace it with a VAV-01 or
delete the VAV-01 and then add a VAV-02 in its place.
To Replace a Node:
1.
Go to the field and physically replace the defective node device with the new device and reconnect
all wiring.
2.
Right-click on the node you want to replace, the Node Menu appears (Figure 27).

Send Config. Data - Sends the previous device’s configuration parameters (CPs) from the LNS
database to the device. This ensures the new node will perform exactly as the old one did.
Exclude Mfg CPs - When selected, this excludes 3rd party manufacturer’s configuration parameters
from being sent from the LNS database to the new node. The Send Config. Data box above must be
checked for this box to be available.
Send Trend - Sends Trend setup data from the LNS database to the device.

LOAD FIRMWARE
Loading firmware is used when you want a different software revision on a controller.
WARNING: Use extreme caution when copying firmware to a controller. Sending the wrong
firmware can have disastrous system effects.
WARNING: Before updating the firmware revision on an FSC or FLC, place any critical points in
Fixed mode from the NWS or place the controller in Hand mode from the field. The process of updating the FSC/FLC firmware from the workstation is lengthy, and during the
update time, the NWS will not receive point statuses or alarms, or issue commands. Take
the necessary measures to ensure the safety and comfort of building occupants and protect
equipment. The panel will reset after the update firmware is complete.

CONNECTION DESCRIPTION TEMPLATE (CDT)
The Connection Description Template (CDT) is the template used to define the parameters of a binding. The
CDT determines the type of addressing and message service to be used, timing parameters, use of authentication
and priority slots, etc. The User can create a new template, or modify existing templates.
The CDT uses five different types of Addressing:
Broadcast - Addresses all the nodes in a subnet or domain.
Neuron ID - Refers to a single node by its unique 48-bit ID
Group -
Refers to numbered group of nodes in the system.
Subnet/Node - Refers to a single node by its domain, subnet, or node (DSN) address (assigned when the
network image is sent to the node for the first time).
Turnaround - Used for connections that take place only within a node.
The CDTs created on the NexSys Network Interface node are displayed in the Connection Description Template
List (Figure 58 ). They will also appear in a scrollable Connection Template list in the Bind To Editor for the
User to select when adding a new bind (please see Section for more information on Binding).

Enter values for the following parameters:
Addressing:
Force Unicast - Forces LNS to use DSN (domain/subnet/node) or NID (Neuron ID) addressing
where it would normally use group (or broadcast) addressing.
No broadcast - Tells LNS to fail if there is no other way to address the message besides broadcast.
Fail group to broadcast - Tells LNS to use broadcast addressing if it has trouble using group
addressing.
Always broadcast - Tells LNS to always use broadcast addressing.
Service Types:
Service Type Override - Tells LNS that you will choose the service type explicitly rather than
allowing LNS to determine it.
Acknowledged - The message is sent out and acknowledged by the receiver (not to be used for large
group bindings causing failure to received Acknowledge messages.
Unacknowledged repeated - The message is sent out many times to ensure the probability of it
reaching its destination.
Unacknowledged - The message is sent out once.
Request Response - Used only for out-and-back messages (e.g.,. NV polls), not used for binds.
Timing Parameters:
Repeat Count Override - Enter a value for the number of times LNS should repeat an unacknowledged-repeated message.
Retry Count Override - Enter a value for the number of times LNS should retry an acknowledged
message if it does not receive an acknowledgment in time.
Transmit Timer Override - Enter a value for the interval rate LNS waits between retries of
acknowledged and request/response messages.
Receive Timer Override - Select a value that tells LNS the time period within which receiving
devices will treat messages from the same source with the same reference ID as
duplicate messages. Repeats of messages using the above service types all use the
same reference ID as the original to identify them as duplicates.
Repeat Timer Override - Select a value for the interval LNS waits between repeats for unacknowledged-repeated messages.
Other:
Authentication Override - Manually overrides control of the LNS message Authentication option.
Use Authentication - Turns the message Authentication option on, telling NexSys to begin sending
and receiving
authentication packets for messages on the network.
Priority Override - Manually overrides control of the LNS message Priority Override option.
Use Priority - Tells LNS that the binding should use a reserved time slot on the network,
helping the message to arrive more quickly to its destination.

OVERVIEW
This guide is intended for someone familiar with routers, TCP/IP and LONWORKS networks. If you are unfamiliar
with any of these please refer to the:
1. Network Basics book for information on TCP/IP, Router Specifications, and NexSys Networks.
2. Installation and Startup section of this manual for information on setting up TCP/IP.
3. Network Wiring Specifications book for information on LONWORKS network wiring.
Before you begin you should know:
1. Router classification type - How will this router be used?
2. Transceiver type of the router you want to install.
3. A descriptive name for the router that designates a specific location.
4. The Neuron ID of the router should you choose not to use the service pin method.
5. Do you need a “plug-in”? A plug-in is a software configuration file that may be required for some routers.
NexSys provides plug-ins for several common routers. Confirm that the plug-in for the router you are installing
is provided by NexSys. If not you must have the plug-in file provided by the router manufacturer.
The steps to add a router are listed below:
1. Add the router to the physical tree. This is known as Defining.
2. Setup the router. This is known as Commissioning.
3. Add nodes to the router.
4. Setup the nodes on the router.
ROUTER CLASSIFICATION TYPES
NexSys supports six different router classification types using one of four LONWORKS routing algorithms. During
the router installation process you must choose a classification type from the list shown below:
1. Configured Router - A configured router forwards only messages received on either of the router’s
domains. A forwarding table at each end is used for each domain.
2. Learning Router - A learning router forwards only messages that have met specific forwarding rules.
The messages are received on either of the router’s domains. Installation is simplified since network
topology information is not required to configure the learning router.
3. Repeater Router - A repeater router forwards all valid messages, in both directions, regardless of the
destination or domain of the message.
Permanent Repeater Router - A permanent repeater router is a repeater router that, once configured,
cannot be readily reconfigured as a standard repeater. It must be deleted, along with all its associated
nodes, and then reinstalled as a standard repeater router.
4. Bridge Router - A bridge router forwards all messages received on either of the router’s domains
regardless of the message’s domain. Bridges are typically used to span one or two domains.
Permanent Bridge Router - A permanent bridge router is a bridge router that, once configured, cannot
be readily reconfigured as a standard bridge router. It must be deleted, along with all its associated
nodes, and then reinstalled as a standard bridge router.
You will need to know the classification type when you install a router.

Routers supported by NexSys include the standard, Coactive, NCB (Network Combiner Module), ENCB
(Ethernet Network Combiner Module), and the Raytheon FTR (Fiber Optic/Twisted Pair) router. In addition, 3rd
party routers, if they are LonMark compliant and have all necessary plug-ins should work with NexSys.
ADDING A ROUTER TO THE PHYSICAL TREE
Adding a router to the Physical Tree requires two steps to be carried out in order: defining and commissioning.
Defining - The Add Router Menu is used to define the router’s name, classification type and farside transceiver
type. The router being defined can be either offline or online and does not have to be physically attached to the
network until the commissioning stage.
Commissioning - The Node Setup Menu is used to commission the defined router. Commissioning writes the
network image, Neuron ID, and two network addresses (one for each side) to a database. The defined router
must be online and physically attached to the network.
To add a router to the Physical Tree:
1.
Click on the Physical Tree to highlight where the router will be added. Right click on an open area
of the tree to bring up the Node Menu (Figure 1). Click Add to display the secondary menu, then
click Router, then click either Before or After to set the router placement on the Physical Tree.
After you select Before or After, the Add Router Menu list of available router types is displayed
(Figure 2).

Rev 2.0
Figure 2. Add Router Menu.
Note 1: If you select the Global Node as the location to add the router, the Router will be placed
on the Physical Tree directly AFTER the Global Node. If you select any other place to add
the router your choices are either BEFORE or AFTER the selected entry point.
Note 2: Routers are classified by type as either, Configured, Learning, Repeater, Bridge, Permanent Repeater, or Permanent Bridge. See the Router Guide for more information.
2.
Click on the Classification type of the router you want to install. Then select the Far Side Transceiver type from the list. NexSys already knows the Near Side Transceiver type based on the
network backbone channel type.
WARNING: CHOOSE THE CORRECT ROUTER TYPE. YOU CAN NOT CHANGE THE
ROUTER HARDWARE TYPE ONCE THE MENU ITEM HAS BEEN SELECTED. IF THE
WRONG TYPE IS CHOSEN, ALL THE NODES UNDER THE ROUTER WILL HAVE TO
BE DELETED, THE ROUTER WILL HAVE TO BE DELETED, AND THE CORRECT
ROUTER WILL HAVE TO BE ADDED.
3.
Enter a Name for the router. This should be as descriptive as possible and indicate the purpose and/
or location of the router. For example, this could be 1st Floor - Zone #1.
NOTE: This field can have a total of 31 characters.
4.
Click
. This will add the router node to the physical tree. However, it is not yet configured.
You must run the Node Setup menu selection to configure the router.
Delay(ms) Box This value represents the average number of milliseconds required for a packet to get onto
the channel once queued. Certain routers have predefined delay values that are automatically chosen
for the specific router. Many routers have a default value of 0, with valid numbers ranging from 0 to
65535. A delay value of 0 uses the default of two packet cycles based on the average packet size.
NOTE: Coactive, NCB, fiber-optic, and ENCB routers must be added in pairs. The local router
will be added first. When you add the remote router, right click on the local router and
choose Add. The option will be Router (for Coactive), Remote NCB, or Remote ENCB.
So, the remote router will be added to the local router.
NOTE: EVERY time a Coactive router is configured from NWS, you must run RTR_CNF.EXE.
Refer to the Coactive router documentation that came with the router.

SETTING UP AN FSC/FLC
FSC OVERVIEW
The Flexible System Controllers (FSC) are microprocessor based controllers that work in conjunction with other
FSCs and all Application Specific Controllers (ASCs) in the NexSys family product line. The FSCs provide
complete flexibility and are user defined. The FSCs can be set up for many purposes. For example, they can be
used to:
· Control an HVAC unit that requires more inputs and outputs than are available on an ASC
· Provide the time for an entire system
· Run custom programs
· To determine occupancy for an ASC
The FSC Editor allows you to add 17 point types to the FSC and then program the FSC for your needs. The
programing is done through CPL (Control Programing Language) and gives you the flexibility to program the
FSC to perform the tasks that are specific to your system.
The FSC-01 allows up to eight I/O modules. The FSC-02 allows four I/O modules. The setup of both FSCs will
be discussed in this chapter.
FLC OVERVIEW
The Flexible Lighting Controller (FLC) is a microprocessor based controller that works in conjunction with
other FLCs, FSCs, and all Application Specific Controllers (ASCs) in the NexSys family product line. The FLC
uses the same CPU and programming as the FSC, but has a specific expansion module designed for lighting
control. The Lighting Control Module (LCM), formerly known as the 8 Triac/4 Digital Input expansion module,
is designed for use with 4 G.E. RR7 or RR9 lighting relays. The other expansion modules (8 UI, 4 DO/4 AO, and
8 DO) can be used in conjunction with the lighting expansion module for additional HVAC and lighting control
sequences. The FLC provides complete flexibility and is user defined. The FLC supports lighting control
applications such as:
· Time of day scheduling
· Remote tenant override
· Wink notification before lighting turn-off
· Zoning of lighting relays
· Use of motion detectors or photocells
The FLC is setup through the FSC Editor which allows you to add 17 point types to the FLC and then program
the FLC for your needs. The programing is done through CPL (Control Programing Language) and gives you the
flexibility to program the FLC to perform the tasks which are specific to your system.
ADDING AN FSC OR FLC TO THE PHYSICAL TREE
Adding an FSC/FLC to the Physical Tree requires three steps to be carried out in order. These three steps are
Defining, Commissioning, and Configuring.
Defining - The Add Node Menu is used to install the FSC/FLC on the tree, define the FSC/FLC’s name and
Program ID. The FSC/FLC being defined can be either off-line or on-line and does not have to be physically
attached to the network until the commissioning stage. You can define multiple devices and then commission
them all at once.
Commissioning - The Node Setup Menu is used to commission the defined FSC/FLC. Commissioning writes
the network image, Neuron ID, and Program ID to a database. The defined FSC/FLC must be on-line and
physically attached to the network for the commissioning process to work.
Configuring - The FSC/FLC Wizard is the editor used to configure a commissioned FSC/FLC. The wizard
works at the panel level to assign basic configuration settings and customize the FSC/FLC to your requirements.

FSC/FLC WIZARD PAGE 1 - CONFIGURE FSC TIME VALUES
The first page to display in the FSC/FLC Wizard is the Configure FSC Time Values page. On this page you set
three time parameters. The first is Status Send Interval which is the time the FSC/FLC will send Status updates. .
The Configure FSC Time Values page is displayed below (Figure 10).
Figure 10. Configure FSC Time Values Page
1.
Set the Status Send Interval by typing in a new value, or using the spin boxes. This is the maximum
amount of time that elapses before the FSC or FLC sends a point status to the NexSys Workstation.
This is done by walking through the list of points and sending one point each time, regardless of the
maximum and minimum send times or the send on delta. This keeps the NexSys Workstation aware
that the FSC is communicating.
Default: 30 seconds Range: 0 to 1 Hour 49 Minutes and 13 seconds
NOTE: The Maximum time you can enter is 1 Hour 49 Minutes and 13 seconds. If you enter a
time greater than 1 Hour 49 Minutes and 13 seconds and click
, the time de-
faults to 1 Hour 49 Minutes and 13 seconds.
2.
Set the Time Broadcast Interval by typing in a new value, or using the spin boxes. This is only
used if this FSC or FLC is the time provider. This interval is the length of time that elapses before the
FSC or FLC synchronizes other controllers to the time.
Default: 15 minutes Range: 0 to 1 Hour 49 Minutes and 13 seconds
NOTE: The Maximum time you can enter is 1 Hour 49 Minutes and 13 seconds. If you enter a
time greater than 1 Hour 49 Minutes and 13 seconds and click

Setting Up a VAV
NexSys Workstation User’s Guide
Rev 2.0
SETTING UP A VAV
The NXA-VAV-01 and NXA-VAV-02 are Application Specific Controllers (ASC) in the NexSys product line.
Their primary purpose is pressure independent Variable Air Volume (VAV) control. These ASCs communicate
on the same LONWORKS network with all of the other NexSys controllers. The VAV-01 is designed for stand-off
or snap track installation on projects which require an external damper actuator. The NXA-VAV-02 is designed
with an integrated actuator for most standard VAV applications.
ADDING A VAV TO THE PHYSICAL TREE
Adding a VAV to the Physical Tree requires three steps to be carried out in order. These three steps are Defining,
Commissioning, and Configuring.
Defining - The Add Node Menu is used to install the VAV on the tree, define the VAV’s name and Program ID.
The VAV being defined can be either off-line or on-line and does not have to be physically attached to the
network until the commissioning stage. You can define multiple devices and then commission them all at once.
Commissioning - The Node Setup Menu is used to commission the defined router. Commissioning writes the
network image, Neuron ID, and Program ID to a database. The defined VAV must be on-line and physically
attached to the network for the commissioning process to work.
Configuring - The VAV Wizard is the editor used to configure a commissioned VAV. The wizard works at the
panel level to assign basic configuration settings and customize the VAV to your requirements.
Advanced editing at the point level is described in the Advanced Point Editing section of this manual.
DEFINING A VAV
The first step to adding a VAV is the defining process.
To add a VAV to the Physical Tree:
1.
Right click on the Global Node or Router where the VAV will be located. The Node pop-up menu
(Figure 1) appears. Click Add to display the secondary menu, then choose Node, then either Before
or After to set the VAV’s placement on the tree. The Add Node menu (Figure 2) appears.
Figure 1. Node Menu.
2.
Figure 2. Add Node Menu.
Click on the VAV in the list of devices and then enter a name for the VAV in the New Node Name:
area. This should be as descriptive as possible and indicate the purpose and/or location of the VAV.
For example, this could be VAV 2nd Floor West Wing.
NOTE: This field can have a total of 31 characters.

COMMISSIONING THE VAV
The second step is to commission the VAV. Any VAV that has not yet been commissioned will have (Never
Commissioned) after the VAV’s name on the tree.
1.
Right click on the uncommissioned VAV to bring up the Node Menu (Figure 4). Select Setup Node
to bring up the Node Setup Menu (Figure 5).
Figure 4. Node Menu
Figure 5. Node Setup Menu
2.
If you know the exact Neuron ID for the VAV, type it in the Neuron ID field. The Neuron ID is
specific to the VAV controller you are setting up and is given to the NexSys Workstation when the
service pin is pressed on the controller. If you do not know the exact Neuron ID number, do not type
anything in this field. Go to Step 3.
3.
If you don’t know the Neuron ID then click the Service Pin button on the Node Setup menu. Next
press the Service Pin on the VAV you are commissioning. This registers the Neuron ID, Program ID
and associated device specific information. Once you press the service pin on the VAV the Setup
Node Menu displays the VAV’s Neuron ID and Program ID information (Figure 6).

CHECK BOX EXPLANATIONS
The node setup pages contain a number of checkboxes that are used in the configuration process. Their settings
determine the information sent and whether it is sent from the LNS database to the device, or vice-versa.
Choose carefully how you use these commands. If used incorrectly, it is possible to overwrite default values that
are not recoverable.
NOTE: SEND moves data from the LNS database to the device.
GET moves data from the device to the LNS database.
Send Network Image - Sends the device’s network address and bindings to the LNS database.
Send Config. Data - Sends the device’s configuration parameters (CPs) from the LNS database to the device.
Force Defaults - Sends the default CPs from the LNS database to the device.

Send Trend - Sends Trend setup data from the LNS database to the device.
Get Config. Data - Gets the device’s CPs from the device and sends them to the LNS database. This is used as a
backup in the event the device requires reconfiguration.
Use as defaults - Checking this box gets the device’s current configuration settings and makes them the
default CP settings for all similar devices. These settings are stored in the LNS database.
Note: Use this command when you have a number of devices that will be configured the same.
Configure the first device the way you want the rest to resemble. Then
Get unknown only - Gets any “unknown” CP data, from the device currently being setup, and sends it to
the LNS database. Typically, unknown CP information is associated with 3rd party devices.
Get Trend - Gets Trend setup data from the device and sends it to the LNS database.
Close window when configuring node done - Closes the configuration window and displays the tree as soon as
the configuration process is done.
5.
Click
to save your changes to the Node Setup Menu, close the wizard and display the
tree. This will complete the commissioning process and remove the Never Commissioned label from
the VAV on the tree. Click
to abandon your changes to the Node Setup Menu. If you
cancel you will be prompted to confirm your cancellation. Confirming the cancellation closes the
wizard and returns to the tree display. Abandoning the cancellation returns you to the wizard.
VAV CONFIGURATION WIZARD
The VAV Wizard is used to configure a newly commissioned VAV. It steps you through a series of editor pages
and allows you to accept the default settings or enter your own settings. As you move through the VAV Wizard
the editor pages presented will vary, based on your preceding choices. For example, if you select Thermistor
instead of Intelligent/TSO, you will automatically skip past the pages for thermostat configuration, since the
thermistor requires no configuration. The VAV flowchart on the next page (Figure 9) shows each of the pages in
the Wizard. The Wizard pages have been numbered to simplify following the configuration process.
Note: Configuration Wizards for other devices have different point types and configuration pages.

This page’s settings are used to calculate thermal load for the controller. The actual space temperature from the
Space Temp Controller and the desired space temperature from the Setpoint Controller and outputs a thermal
load value. This values is then fed to the Economizer Controller, the Fan Controller, and the Heating/Cooling
Controller. The output of the Emergency Command Controller and the output of the Application Mode Controller are also used at in the determination of thermal load. The PID Parameters for Thermal Load page is displayed below (Figure 16).

1.
Enter the Heating and Cooling PID Prop. Integ. Derv. gains. A PID loop always requires two
values (actual and desired) that have the same engineering units, such as two °F temperatures, two
CFM air flow readings, etc., and generates a command to correct the error between them. Typically,
this command is then used with some other point for a final action. In this case, the point takes the
actual space temperature and the desired space temperature and outputs a thermal load value that is
fed to the Economizer, Fan Controller, and the Heating/Cooling Controller.
The Proportional (Prop.) gain is how much error between the two values you want for 100% control.
Proportional gain is always in the engineering units of the input variables, in this case °F. Decreasing
the proportional gain increases the control.
Default: 4° F
The Integral (Integ.) gain is how much time elapses before 100% of the error is added back into the
control. Integral gain is always in seconds. Decreasing the integral gain increases the control.
Default: 2000 Seconds

Enter the K Factor. K Factor is the actual CFM at a measured Velocity pressure of 1 inch water
column. K Factor = CFM / SqRt of Inches of water column. There are 3 different methods to
determine K Factor:
• From the Dual Duct VAV box manufacturer’s field calibration chart, find the curve for the box
size in your system and whatever CFM value exists at exactly 1” w.c. is the K Factor. For
example, on a particular box manufacturer’s field calibration chart, a 10” box supplies 1450
CFM at 1” w.c. Therefore, you would enter 1450 for the K Factor.

Setting Up a VAV
NexSys Workstation User’s Guide
Rev 2.0
• From the Dual Duct VAV box manufacturer’s field calibration chart, find a point where the
inches of water column and a curve intersect with a CFM vertical line. Then to determine K
Factor use the following equation: K Factor = CFM / SqRt of Inches of water column. For
example, on a particular box manufacturer’s field calibration chart, a 10” box supplies 250
CFM at .03” w.c. Using the above equation, K Factor = 250 / Ö .03. You would enter 1443 for
the K Factor.
• Obtain an exact CFM reading at 1” w.c. from the box manufacturer.
Default: 300
2.
Enter the K Factor Calibration. K Factor Calibration is calibration, or verification, of K Factor to
actual field conditions. To determine K Factor Calibration:
1. Set the VAV box to Maximum CFM position and measure all diffusers for CFM (Measured
CFM).
2. Record the actual CFM reading at the Intelligent Stat or NexSys Workstation at the
maximum position (Read CFM).
3. Calculate the difference in CFM (Measured CFM - Read CFM).
4. Use the following equation to calculate K Factor Calibration:
K Factor Calibration = ( Measured CFM - Read CFM) / SqRt of Inches of water column
For example, on a particular box manufacturer’s field calibration chart, a 6” box supplies 500
CFM at 1” w.c. When you command the box to maximum, you get a reading of 490 CFM on
the Intelligent Stat. The Balance Commissioner gets a reading of 505 CFM. Using a manometer, you determine .98” w.c. at 640 CFM.
Now plugging in the numbers to determine K Factor Calibration:
K Factor Calibration = ( Measured CFM - Read CFM) / SqRt of Inches of water column
K Factor Calibration = (505-490)/Ö.98
K Factor Calibration = (15)/.9899494
K Factor Calibration = 15.15
Default: 0
NOTE: For more information regarding K Factor and K Factor Calibration, see the VAV Engineering Guide.
3.
Enter the Flow Offset. Flow Offset is a true offset used to make small adjustments at low CFM
reading. The Flow Offset is limited to no more than 5% of the maximum CFM value. This offset can
be used for inadequate laminar air flow entering the VAV box, installation variances, etc.

This point is the desired position of the damper. This point takes the actual air flow from the Flow Sensor and
the desired air flow from the Air Flow Reset Controller and outputs a value to either the Damper Actuator Inc. or
Damper Actuator Dec. This point also looks at the output of the Emergency Command Controller before
determining the output to the damper. The Flow PID Parameters Page is displayed below (Figure 20).

System Setup
Enter the Air Flow Prop. Integ. Derv. gains. A PID loop always requires two values (actual and
desired) that have the same engineering units, such as two °F temperatures, two CFM air flow
readings, etc. and generates a command to correct the error between them. Typically, this command is
then used as with some other point for a final action. In this case, the point takes the actual air flow
and the desired air flow and outputs a value to the Damper Actuator Incr. or Damper Actuator Decr.

The Proportional (Prop.) gain is how much error between the two values you want for 100% control.
Proportional gain is always in the engineering units of the input variables, in this case CFM. Decreasing
the proportional gain increases the control.
Default: 500 CFM
The Integral (Integ.) gain is how much time elapses before 100% of the error is added back into the
control. Integral gain is always in seconds. Decreasing the integral gain increases the control.
Default: 120
The Derivative (Deriv.) gain controls based on how fast the temperature is changing, and attempts to
sense rapid changes. The derivative gain is always in seconds. Increasing the derivative gain, decreases
control.
Default: 0
NOTE: It is recommended that the derivative gain always be 0.
NOTE: If your control is too sensitive and your system is oscillating, you need to increase the
proportional and/or integral gains. If your control is too insensitive and it is taking too long
to reach the active setpoint, then you need to decrease the proportional and/or integral
gains.

specifications if you are unsure of your damper actuator’s drive time.
4.
Select whether the damper Direction is Clockwise or Counter-Clockwise. This sets the damper to
move in a Clockwise or Counter-Clockwise direction. This is useful if the damper has been wired
wrong in the field.
Default: Clockwise
NOTE: Due to the integrated actuator, a VAV-02 controller should always be Direct. Proportional
gain is always in the engineering units of the input variables, in this case ° F. Decreasing
the proportional gain increases the control.

length correlates directly with the value under regulation. For example, a pulse width might be 5 seconds and
the output value may range from 0-100%. If the pulse sent were 2.5 seconds, the controller would regulate the
device to 50%. A 2.5 second signal would be sent by the controller each time the modulator cycles. The PWM
Reheat page (Figure 25) is displayed below.

The Pulse Width is the maximum length of a pulse. If a maximum pulse is sent, the output value will
be 100%. If the pulse sent minus the minimum on time is zero seconds, then the output value will be
0%. When the Minimum On Time, Pulse Width, and Minimum Off Time are added together, you
find the length of the pulse modulation cycle. If you wish to have a cycle length of 60 seconds, the
minimum on time is set to 0, and a maximum pulse length is set to 5 seconds, then the minimum off
time would be set to 55 seconds. See Figure 31. Refer to the note under step 6.

SETTING UP A HEAT PUMP
The NXA-HPU-01 is an Application Specific Controller (ASC) in the NexSys product line. Its primary purpose
is to provide control for one individual heat pump; either a stand alone unit or one of the units in a closed loop
system. This ASC communicates on the same LONWORKS network with all of the other NexSys controllers. The
NXA-HPU-01 is designed for standoff or snap-track installation.
ADDING A HEAT PUMP TO THE PHYSICAL TREE
Adding a Heat Pump to the Physical Tree requires three steps to be carried out in order. These three steps are
Defining, Commissioning, and Configuring.
Defining - The Add Node Menu is used to install the Heat Pump on the tree, define the Heat Pump’s name and
Program ID. The Heat Pump being defined can be either off-line or on-line and does not have to be physically
attached to the network until the commissioning stage. You can define multiple devices and then commission
them all at once.
Commissioning - The Node Setup Menu is used to commission the defined Heat Pump. Commissioning writes
the network image, Neuron ID, and Program ID to a database. The defined Heat Pump must be on-line and
physically attached to the network for the commissioning process to work.
Configuring - The Heat Pump Wizard is the editor used to configure a commissioned Heat Pump. The wizard
works at the panel level to assign basic configuration settings and customize the Heat Pump to your requirements.
Advanced editing at the point level is described in the Advanced Point Editing section of this manual.
DEFINING A HEAT PUMP
To add a Heat Pump to the Physical Tree:
1.
Right click on the Global Node or Router where the Heat Pump will be located. The Node pop-up
menu (Figure 1) appears. Click Add to display the secondary menu, then choose Node, then either
Before or After to set the Heat Pump’s placement on the tree. The Add Node menu (Figure 2)
appears.
Figure 1. Node Menu.
2.
Figure 2. Add Node Menu.
Click on the Heat Pump in the list of devices and then enter a name for the Heat Pump in the New
Node Name: area. This should be as descriptive as possible and indicate the purpose and/or location
of the Heat Pump. For example, this could be Heat Pump 2nd Floor West Wing.
NOTE: This field can have a total of 31 characters.

If you know the exact Neuron ID for the Heat Pump, type it in the Neuron ID field. The Neuron ID
is specific to the Heat Pump controller you are setting up and is given to the NexSys Workstation
when the service pin is pressed on the controller. If you do not know the exact Neuron ID number, do
not type anything in this field. Go to Step 3.
3.
If you don’t know the Neuron ID then click the Service Pin button on the Node Setup menu. Next
press the Service Pin on the Heat Pump you are commissioning. This registers the Neuron ID,
Program ID and associated device specific information. Once you press the service pin on the Heat
Pump the Setup Node Menu displays the Heat Pump’s Neuron ID and Program ID information
(Figure 6).

CHECK BOX EXPLANATIONS
The node setup pages contain a number of checkboxes that are used in the configuration process. Their settings
determine the information sent and whether it is sent from the LNS database to the device, or vice-versa.
Choose carefully how you use these commands. If used incorrectly, it is possible to overwrite default values that
are not recoverable.
NOTE: SEND moves data from the LNS database to the device.
GET moves data from the device to the LNS database.
• Send Network Image - Sends the device’s network address and bindings to the LNS database.
• Send Config. Data - Sends the device’s configuration parameters (CPs) from the LNS database to the device.
• F o rce Defaults - Sends the default CPs from the LNS database to the device.
• Send Trend - Sends Trend setup data from the LNS database to the device.
• Get Config. Data - Gets the device’s CPs from the device and sends them to the LNS database. This is used
as a backup in the event the device requires reconfiguration.
• Use as defaults - Checking this box gets the device’s current configuration settings and makes them the
default CP settings for all similar devices. These settings are stored in the LNS database.
Note: Use this command when you have a number of devices that will be configured the same.
Configure the first device the way you want the rest to resemble. Then
• Get unknown only - Gets any “unknown” CP data, from the device currently being setup, and sends it to
the LNS database. Typically, unknown CP information is associated with 3rd party devices.
• Get Trend - Gets Trend setup data from the device and sends it to the LNS database.
• Close window when configuring node done - Closes the configuration window and displays the tree as soon
as the configuration process is done.

Click
to save your changes to the Node Setup Menu, close the wizard and display the
tree. This will complete the commissioning process and remove the Never Commissioned label from
the Heat Pump on the tree. Click
to abandon your changes to the Node Setup Menu. If
you cancel you will be prompted to confirm your cancellation. Confirming the cancellation closes the
wizard and returns to the tree display. Abandoning the cancellation returns you to the wizard.

move through the Configuration Wizard the editor pages presented will vary, based on your preceding choices.
For example, if you select Thermistor instead of Intelligent/TSO, you will automatically skip past the pages for
thermostat configuration, since the thermistor requires no configuration. The Heat Pump flowchart (Figure 9)
shows each of the pages in the Wizard. The Wizard pages have been numbered to simplify following the

HEAT PUMP WIZARD PAGE 5 - PID PARAMETERS FOR THERMAL LOAD
This page’s settings are used to calculate thermal load for the controller. The actual space temperature from the
Space Temp Controller and the desired space temperature from the Setpoint Controller and outputs a thermal
load value. This values is then fed to the Economizer Controller, the Fan Controller, and the Heating/Cooling
Controller. The output of the Emergency Command Controller and the output of the Application Mode Controller are also used at in the determination of thermal load. The PID Parameters for Thermal Load page is displayed below (Figure 14).
Figure 14. PID Parameters for Thermal Load Page
1.
Enter the Heating and Cooling PID Prop. Integ. Derv. gains. A PID loop always requires two
values (actual and desired) that have the same engineering units, such as two °F temperatures, two
CFM air flow readings, etc., and generates a command to correct the error between them. Typically,
this command is then used with some other point for a final action. In this case, the point takes the
actual space temperature and the desired space temperature and outputs a thermal load value that is
fed to the Economizer, Fan Controller, and the Heating/Cooling Controller.
The Proportional (Prop.) gain is how much error between the two values you want for 100% control.
Proportional gain is always in the engineering units of the input variables, in this case °F. Decreasing
the proportional gain increases the control.
Default: 4° F
The Integral (Integ.) gain is how much time elapses before 100% of the error is added back into the
control. Integral gain is always in seconds. Decreasing the integral gain increases the control.
Default: 2000 Seconds
The Derivative (Deriv.) gain controls based on how fast the temperature is changing, and attempts to
sense rapid changes. The derivative gain is always in seconds. Increasing the derivative gain, decreases
control.
Default: 0
NOTE 1: It is recommended that the Derivative gain always be 0.
NOTE 2: If your control is too sensitive and your system is oscillating, you need to increase the
Proportional and/or Integral gains. If your control is too insensitive and it is taking too long
to reach the Active Setpoint, then you need to decrease the Proportional and/or Integral
gains.
2.
Enter the Heating and Cooling Scan Rates. This is how often the Heating and Cooling Temperature PID loops are recalculated.
Default:
Cooling = 6 Seconds
Heating = 7 Seconds
3.
Enter the Default Output. This is a thermal load that is forced to the system in the event of a
controller failure or an invalid space temperature, such as a short or open connection to a sensor or
stat.
Default: 50%

Setting Up a PEC
NexSys Workstation User’s Guide
Rev 2.0
SETTING UP A PEC
The NXA-PEC-01 is an Application Specific Controller (ASC) in the NexSys product line. The Packaged
Equipment Controller (PEC) is designed to support four types of packaged equipment systems: Fan Coil Units
(FCUs) and Roof Top Units (RTUs), Unit Ventilators (UVs), and Air Handling Units (AHUs). This ASC
communicates on the same LONWORKS network with all of the other NexSys controllers. The NXA-PEC-01 is
designed for standoff or snap-track installation.
ADDING A PEC TO THE PHYSICAL TREE
Adding a PEC to the Physical Tree requires three steps to be carried out in order. These three steps are Defining,
Commissioning, and Configuring.
Defining - The Add Node Menu is used to install the PEC on the tree, define the PEC’s name and Program ID.
The PEC being defined can be either off-line or on-line and does not have to be physically attached to the
network until the commissioning stage. You can define multiple devices and then commission them all at once.
Commissioning - The Node Setup Menu is used to commission the defined router. Commissioning writes the
network image, Neuron ID, and Program ID to a database. The defined PEC must be on-line and physically
attached to the network for the commissioning process to work.
Configuring - The PEC Configuration Wizard is the editor used to configure a commissioned PEC. The PEC
Wizard works at the panel level to assign basic configuration settings and customize the PEC to your requirements.
DEFINING A PEC
The first step to adding a PEC is the defining process.
To add a PEC to the Physical Tree:
1.
Right click on the Node or Router where the PEC will be located. The Node pop-up menu (Figure 1)
appears. Click Add to display the secondary menu, then choose Node, then either Before or After to
set the PEC’s placement on the tree. The Add Node menu (Figure 2) appears.
Figure 1. Node Menu.
2.
Figure 2. Add Node Menu.
Click on the PEC in the list of devices and then enter a name for the PEC in the New Node Name:
area. This should be as descriptive as possible and indicate the purpose and/or location of the PEC.
For example, this could be PEC 2nd Floor West Wing.
NOTE: This field can have a total of 31 characters.

Figure 3. Physical Tree with Newly Added Uncommissioned PEC
COMMISSIONING THE PEC
The second step is to commission the PEC. Any PEC that has not yet been commissioned will have (Never
Commissioned) after the PEC’s name on the tree.
1.
Right click on the uncommissioned PEC to bring up the Node Menu (Figure 4). Select Setup Node
to bring up the Node Setup Menu (Figure 5).
Figure 4. Node Menu

2.
If you know the exact Neuron ID for the PEC, type it in the Neuron ID field. The Neuron ID is
specific to the PEC controller you are setting up and is given to the NexSys Workstation when the
service pin is pressed on the controller. If you do not know the exact Neuron ID number, do not type
anything in this field. Go to Step 3.
3.
If you don’t know the Neuron ID then click the Service Pin button on the Node Setup menu. Next
press the Service Pin on the PEC you are commissioning. This registers the Neuron ID, Program ID
and associated device specific information. Once you press the service pin on the PEC the Setup
Node Menu displays the PEC’s Neuron ID and Program ID information (Figure 6).

CHECK BOX EXPLANATIONS
The node setup pages contain a number of checkboxes that are used in the configuration process. Their settings
determine the information sent and whether it is sent from the LNS database to the device, or vice-versa.
Choose carefully how you use these commands. If used incorrectly, it is possible to overwrite default values
that are not recoverable.
NOTE:
SEND moves data from the LNS database to the device.
GET moves data from the device to the LNS database.
Send Network Image - Sends the device’s network address and bindings to the LNS database.
Send Config. Data - Sends the device’s configuration parameters (CPs) from the LNS database to the device.
Force Defaults - Sends the default CPs from the LNS database to the device.
Send Trend - Sends Trend setup data from the LNS database to the device.
Get Config. Data - Gets the device’s CPs from the device and sends them to the LNS database. This is used as
a backup in the event the device requires reconfiguration.
Use as defaults - Checking this box gets the device’s current configuration settings and makes them the
default CP settings for all similar devices. These settings are stored in the LNS database.
Note: Use this command when you have a number of devices that will be configured the same.
Configure the first device the way you want the rest to resemble. Then
Get unknown only - Gets any “unknown” CP data, from the device currently being setup, and sends it to
the LNS database. Typically, unknown CP information is associated with 3rd party devices.
Get Trend - Gets Trend setup data from the device and sends it to the LNS database.
Close window when configuring node done - Closes the configuration window and displays the tree as soon
as the configuration process is done.

CONFIGURATION WIZARD (PEC)
The PEC Configuration Wizard is used to configure a newly commissioned PEC. It steps you through a series
of editor pages and allows you to accept the default settings or enter your own settings. As you move through the
Configuration Wizard the editor pages presented will vary, based on your preceding choices. For example, if you
select Thermistor instead of Intelligent/TSO, you will automatically skip past the pages for thermostat configuration, since the thermistor requires no configuration. The PEC flowchart (Figure 9) shows each of the pages in the
Wizard. The Wizard pages have been numbered to simplify following the configuration process.
Note: Configuration Wizards for other devices have different point types and configuration pages.

This page’s settings are used to calculate thermal load for the controller. The actual space temperature from the
Space Temp Controller and the desired space temperature from the Setpoint Controller and outputs a thermal
load value. This values is then fed to the Economizer Controller, the Fan Controller, and the Heating/Cooling
Controller. The output of the Emergency Command Controller and the output of the Application Mode Controller are also used at in the determination of thermal load. The PID Parameters for Thermal Load page is displayed below (Figure 16).

Enter the Heating and Cooling PID Prop. Integ. Derv. gains. A PID loop always requires two
values (actual and desired) that have the same engineering units, such as two °F temperatures, two
CFM air flow readings, etc., and generates a command to correct the error between them. Typically,
this command is then used with some other point for a final action. In this case, the point takes the
actual space temperature and the desired space temperature and outputs a thermal load value that is
fed to the Economizer, Fan Controller, and the Heating/Cooling Controller.
The Proportional (Prop.) gain is how much error between the two values you want for 100% control.
Proportional gain is always in the engineering units of the input variables, in this case °F. Decreasing
the proportional gain increases the control.
Default: 4° F

The Integral (Integ.) gain is how much time elapses before 100% of the error is added back into the
control. Integral gain is always in seconds. Decreasing the integral gain increases the control.
Default: 2000 Seconds
The Derivative (Deriv.) gain controls based on how fast the temperature is changing, and attempts to
sense rapid changes. The derivative gain is always in seconds. Increasing the derivative gain, decreases
control.
Default: 0
NOTE 1: It is recommended that the Derivative gain always be 0.
NOTE 2: If your control is too sensitive and your system is oscillating, you need to increase the

ADVANCED PEC EDITING
EDITING POINTS
All 31 points on the PEC controller are editable and you edit the points to tune your PEC system. Each point has
a predefined point number and point type which are not editable. To edit a point on the PEC controller:
1.
Click on the PEC you want to edit, then click on the Points (Figure 7).
Figure 7. PEC Points Page with Point #11 - User Setpoint Highlighted.
2.
Double click on the point you want to edit. The Point Editor for the selected point displays.
3.
Edit the point, as necessary. Specific procedures for editing points are discussed on the following
pages:
EDITING POINT #1 - DISCHARGE AIR TEMP (ANALOG INPUT)
Point #1 measures the temperature of the discharge air from a thermistor input. This point is used by the Mixed
Air PID (Point #19) in determining the desired damper position.
EDITING POINT #2 - MIXED AIR TEMP (ANALOG INPUT)
Point #2 measures the temperature of the mixed air from a thermistor input. This point is used by the Mixed Air
PID (Point #19) in determining the desired damper position.

EDITING POINT #3 - SPACE TEMP (ANALOG INPUT)
Point #3 is a temperature input. Depending on the exact configuration, this could be either Space Temperature or
an auxiliary temperature, Return Air Temperature. If you are using an ESUSA sensor, this point is Space
Temperature and measures the temperature of the zone under control. If you are using an ESUSA thermostat,
then this point can be used as return air temperature.
EDITING POINT #4 - OUTSIDE AIR/SUPPLY WATER TEMP (ANALOG INPUT)
Point #4 measures the temperature of the outside air or the supply water from a thermistor input. Depending on
the system configuration, this point could be used by the Winter/Summer Controller (Point 21) in determining
the summer or winter mode of control for a two pipe system. If this point measures outside air temperature, this
point provides the OAT for display on the Intelligent STAT.
EDITING POINT #5 - FAN STATUS INPUT (DIGITAL INPUT)
Point #5 is a discrete input and is used for fan status feedback. The main purpose of this point is to add safety to
the system by allowing verification of the state of the fan for equipment protection.
EDITING POINT #6 - EMERGENCY SHUTDOWN (DIGITAL INPUT)
Point #6 is for the Emergency Shutdown. This input is wired to an external sensor in an area that should be able
to cause an Emergency Shutdown for the local controller.
EDITING POINT #7 - SPACE TEMP CONTROLLER
This point holds the Space Temperature and generates alarms. If you selected Intelligent on the Thermostat Page
for the PEC, then this value comes from an ESUSA STAT. If Thermistor was selected, then this value comes
from the Space Temp (Point #3) or an external LON device.
EDITING POINT #8 - INDOOR AIR QUALITY CONTROLLER
Indoor Air Quality (IAQ) is the quality of the air expressed in a percentage with 0% being the best and 100%
being the worst. This point is used to tell the controller to increase the Minimum Flow Setpoint to compensate
for poor IAQ. The intention is to increase air flow to provide additional fresh air to displace air currently in the
controlled space.
EDITING POINT #9 - OUTSIDE AIR TEMP
This point receives the outside air temperature from another point or another controller. This point is used by the
Analog Output (Point 26) in determining the desired damper position. This point differs from the Outside Air/
Supply Water Temp (Point #4) because Point #4 is an actual hardware point, while Point #9 is a software point.
Point #9 allows you to bind an Outside Air Temperature from another controller.
EDITING POINT #10 - MANUAL OCCUPANCY CONTROLLER
This point determines the state of occupancy for the controller (Occupied, Unoccupied, Economy). The state of
occupancy determines which setpoints are currently in use by the controller. The possible states of occupancy
the controller can be placed in are shown on the Point Command window (Figure 13). Although the list contains
4 states, the PEC controller only responds to 3 different states. The states are:
OCCUPIED - Uses the Occupied Heating and Cooling Setpoints.
UNOCCUPIED - Uses the Unoccupied Heating and Cooling Setpoints.
BYPASS - Not used in the PEC controller.
STANDBY - Uses the Economy Heating and Cooling Setpoints.

EDITING POINT #11 - USER SETPOINT CONTROLLER
This is the user desired setpoint. This point is given to the controller by the user through the Intelligent or TSO
STAT. This point is used in conjunction with the Setpoint Controller (Point # 18) to determine an offset (by
comparing the Occupied Cooling Setpoint to the User Setpoint) and then apply that offset to the current setpoints to determine the Active Setpoint.
EDITING POINT #12 - OVERRIDE CONTROLLER
This point provides the override function and timing for the controller. Override is used to cause the system to
control to the occupied setpoints when the building is not normally occupied. Override places the controller back
into occupied mode for a specified time (set in the Override Time field). When this time expires, the previous
control (setpoints) resumes.
EDITING POINT #13 - APPLICATION MODE CONTROLLER
This point sets the overall operation mode of the PEC controller. The possible modes the controller can be
placed in are listed below. Although the list contains ten modes, the PEC controller only responds to six different
modes.
The modes are:
AUTO - This is the normal mode for the PEC. The controller cools and heats over the whole range of possible
setpoints. Control is provided between -100% to 100% thermal load.
HEAT - The controller is in heat mode only. Control is provided between -100% and 0% thermal load.
MORNING WARMUP - The economizer damper is fully closed, and then the controller functions as usual.
See the PEC Engineering Guide for more information.
COOL - The controller is in cool mode only. Control is provided between 0% and 100% thermal load.
NIGHT PURGE - The economizer damper is driven to maximum.
PRECOOL - Not used in the PEC controller.
OFF - The controller is not providing control and is fixed at 0% thermal load.
TEST - Not used in the PEC controller.
EMERGENCY HEAT - Not used in the PEC controller.
FAN ONLY - Not used in the PEC controller.
EDITING POINT #14 - MANUAL RESET
This point allows the network to send a manual reset command to the Low Limit Shutdown controller in order to
facilitate a reset.
EDITING POINT #15 - LOW LIMIT SHUTDOWN
This point determines if conditions are met to perform a low limit shutdown. This is determined by comparing
the Mixed Air Temp (Point #2) and the Low Limit Setpoint. If the Mixed Air Temp is below the Low Limit
Setpoint, then a low limit shutdown is performed and the unit undergoes an Emergency Shutdown. Low Limit
Shutdown is used for equipment protection mainly to prevent coil freeze-up.
EDITING POINT #16 - LOCAL EMERGENCY SHUTDOWN
This point determines if conditions are met to perform a local emergency shutdown. This is determined by the
Emergency Shutdown (Point #6) and is used to tell the controller when to assume emergency operation mode
operations and only effects the local unit.
EDITING POINT #17 - LON EMERGENCY SHUTDOWN
216
System Setup
© 2000 Johnson Controls, Inc.
Rev 2.0
NexSys Workstation User’s Guide
Setting Up a PEC
This point determines if conditions are met to perform a LON emergency shutdown. This is determined by a
point that is bound from another controller to the PEC-01 controller and is used to tell the controller when to
assume emergency operation mode operations. This point is used for smoke control. The possible states of
emergency the controller can be placed in are shown below:
NORMAL - No emergency operations - the controller is controlling to application mode.
PRESSURIZE - The controller drives the economizer damper to maximum, the fan is turned ON, and the
thermal load is forced to 0%.
DEPRESSURIZE - The controller drives the economizer damper to full closed, the fan is turned OFF, and
the thermal load is forced to 0%.
PURGE - The controller drives the economizer damper to maximum, the fan is turned ON, and the thermal
load is forced to 0%.
SHUTDOWN - The controller drives the economizer damper to full closed, the fan is turned OFF, and the
thermal load is forced to 0%.
EDITING POINT #18 - SETPOINT CONTROLLER
This point determines the setpoint the controller is currently using. This point takes the User Setpoint Controller
(Point #11), compares it to the occupied cooling setpoint entered on this point editor, and determines an offset.
This offset is then added to the occupied heating and cooling and economy heating and cooling setpoints and the
active setpoint is determined. The output of the Manual Occupancy Controller (Point #10), the output of the
Override Controller (Point #12), and the output of the Space Temp Controller (Point #7) are also looked at in the
determination of setpoint.
NOTE 1: The offset is never applied to the unoccupied setpoints.
NOTE 2: The values entered on this screen set up a basic relationship between the setpoints.
Even though an offset is determined and added to the setpoints, the numbers entered on
this screen do not change. For more information, see the PEC Engineering Guide.
EDITING POINT #19 - MIXED AIR PID CONTROLLER
This point is used to determine the mixed air PID damper position. This point takes the Discharge Air Temp
(Point #1) and the Mixed Air Setpoint (entered in this editor) and outputs a Mixed Air PID damper position in
percent. This is not the absolute damper position because this position is based only on the Discharge Air Temp
and the Mixed Air Setpoint. This output is then fed to the Economizer Controller (Point #23) and the exact
damper position is determined.
NOTE 1: It is recommended that the derivative gain always be 0.
NOTE 2: If your control is too sensitive and your system is oscillating, you need to increase the
proportional and/or integral gains. If your control is too insensitive and it is taking too long
to reach the active setpoint, then you need to decrease the proportional and/or integral
gains.
EDITING POINT #20 - EMERGENCY COMMAND CONTROLLER
This point is used to tell the controller when to assume emergency operation mode operations. This point looks
at the Low Limit Shutdown (Point #15), the Local Emergency Shutdown (Point #16), and the LON Emergency
(Point #17) and determines the emergency mode of operations. The possible states of emergency the controller
can be placed in are shown on the Point Command window (Figure 26). The emergency states are:
NORMAL - No emergency operations - the controller is controlling to application mode.
PRESSURIZE - The controller drives the economizer damper to maximum, the fan is turned ON, and the
thermal load is forced to 0%.

PURGE - The controller drives the economizer damper to maximum, the fan is turned ON, and the thermal load
is forced to 0%.
SHUTDOWN - The controller drives the economizer damper to full closed, the fan is turned OFF, and the
thermal load is forced to 0%.
EDITING POINT #21 - WINTER/SUMMER CONTROLLER
This point determines the summer or winter mode for a two-pipe system. This mode is determined by looking at
the Outside Air/Supply Water Temp (Point #4). The output of the Winter/Summer Controller (Point #21) is fed
to the Heating/Cooling Controller (Point #25).
EDITING POINT #22 - TEMP PID CONTROLLER
This point calculates thermal load for the controller. It takes the actual space temperature from the Space Temp
Controller (Point #7) and the desired space temperature from the Setpoint Controller (Point #18) and outputs a
thermal load value that is fed to the Economizer Controller (Point #23), the Fan Controller (Point #24), and the
Heating/Cooling Controller (Point #25). The output of the Emergency Command Controller (Point #20) and the
output of the Application Mode Controller (Point #13) are also used at in the determination of thermal load.
EDITING POINT #23 - ECONOMIZER CONTROLLER
This point determines the economizer damper position. The damper position is determined by looking at the
Indoor Air Quality Controller (Point #8), the Outside Air/Supply Water Temp (Point #4), the Mixed Air PID
Controller (Point #19), the Manual Occupancy Controller (Point #10), the Emergency Command Controller
(Point #20), and the Temp PID Controller (Point #22).
EDITING POINT #24 - FAN CONTROLLER
This point determines when the fan should be ON or OFF. This point looks at the output the Manual Occupancy
Controller (Point #10) and the output of the Emergency Command Controller (Point #20) to determine if the fan
should be ON or OFF. The output of this point is sent to the Fan Output (Point #27) which is the control point
for the fan.
NOTE: This point is only the state of the fan as the sequence of operation determines it to be.
Fan Status (Point #5) can be used as a feedback to determine the actual status of the fan.
EDITING POINT #25 - HEATING/COOLING CONTROLLER
This point determines whether the system is heating or cooling. Many factors are looked at in this determination.
Depending on what is entered in this point editor, this can determine heating or cooling, discrete or floating
control, 2 or 4 pipe system, etc.
NOTE: The fields on this screen change depending on the Cooling Type and Heating Type
selected.
EDITING POINT #26 - ANALOG OUTPUT
NOTE:
This point is used to control the Economizer Damper.
This point is the hardware output of the Economizer Controller (Point #23). This point receives the economizer
damper position as a percent (0 to 100) from the Economizer Controller and supplies an output signal of 0 to 10
VDC to control the economizer damper actuator.
EDITING POINT #27 - DIGITAL OUTPUT #1 FAN ACTUATOR OUTPUT
218
Point #27 controls the state of the fan (ON or OFF). This point is the hardware output of the Fan Controller
(Point #24) and applies the control.

Binding
NexSys Workstation User’s Guide
Rev 2.0
OVERVIEW
Binding is the process that defines connections between LONWORKS Devices . These connections define the data
that devices on the network share with one another. To share this data, NexSys connects (or “binds”) a point on a
device to another point that needs that same data. This point can either be on the same device or it can be a
different device on the network.
NOTE: The words bind and connection can be used interchangeably.
Binding is accomplished by connecting Network Variables (NVs). NWS uses the Bind Editor to bind Network
Variable Outputs (NVOs) to Network Variable Inputs (NVIs). As stated above, Network Variables can be bound
from one node to another node, or bound internally on the same node. For more information on Points and
Network Variables, please see Section Five, Operations - Chapter One.
Binding gives the User the ability to use Network Variables over the LON instead of physical wiring between the
FSC and the VAV. In Figure 1, a temperature NVO on one node (a VAV controller) is bound to a temperature
NVI on another node (in this example an FSC). When the temperature from the VAV is broadcast on the LON, it
is received by the FSC. Thus, the VAV controller shares the temperature reading from its temperature sensor with
the FSC without the need for any physical connection between the two devices.

EDITING AND VIEWING BINDINGS
All Bindings for a node are accessed through the Binding Editor (Figure 2). The Binding Editor Window
consists of three smaller windows:
•
NV - The NV window (Figure 3) displays a scrollable list of all NVs available on the node.
•
Connects To - When an NV is selected from the NV Window, the Connects To Window (Figure 4)
displays the NV it is connected to, if the connection (binding) exists.
•
Binding Summary - The Binding Summary Window (Figure 5) displays a scrollable list of all the
bindings for the selected node.

OVERVIEW
NexSys CPL (Control Programming Language) provides the User with the means to create and edit
graphical programs. CPL programming allows the User to build a ‘picture’ of their desired control
strategy. These programs, called CPL Pages, can then be stored on the FSC (Flexible System Controller)
or in the CPL Library. The CPL Library is available for storing common programs for exporting or
importing.
Using the NexSys CPL Editor, the User builds a ‘picture’ of their control strategy using graphical objects
called ‘CPL Blocks’. The User places these objects on a CPL Page, and then enters specific values and
settings for that block. The User defines the proper control flow by using lines to represent connections. The resulting ‘picture’ becomes a working program. A sample control block (Figure 1) is shown
below in Edit mode. In the Monitor mode, the program is enabled, and values would be display at the
inputs/outputs of each block.

CPL PAGES SUBTREE
The CPL Pages subtree (Figure 2) is located within the FSC controller node. All CPL functions (except
CPL Library functions) are accessed through this subtree. When you select CPL Pages from the Physical Tree, the CPL Page List panel opens to the right.
The CPL Page List panel (Figure 3) shows the status and index numbers of all CPL Pages residing on
the node. The Status indicates whether the page is enabled (currently running) or disabled. The Index
number is the internal number assigned to the page by NWS.

The Functions drop-down menu (Figure 13) is shown as it will appear on the CPL Block Menu. Use the arrows
at the top and bottom of the menu to view all available functions. A Function is a predefined mathematical
operation used to perform higher level calculations for control systems.
Many of the Function blocks use identical settings windows. Two of the most commonly used windows are the
Timing Window (Figure 14) and the Descriptor Window (Figure 15).
The Timing Window prompts for two values:
1.
The desired interval in hours, minutes, and seconds.
2.
The desired offset of the interval in hours, minutes, and seconds.
Note: All CPL Function Blocks are referenced to 2400 hours 00 seconds of the current day.
The Descriptor Window requires a descriptive name for the block that allows the User to easily
identify it. A maximum of 32 characters is allowed. This descriptor will display above the block, and
also moves with it around the CPL Page.

ACCUMULATOR
The Accumulator block (Figure 18) samples the input for the designated interval and outputs the value of that
sampling. Each time the interval is repeated, the value of the current sample is added to the previous values for
an accumulative output (Output = Previous sample +current sample).
The optional Reset input resets the output to zero, and the accumulation process begins again at the next
interval.

CALCULATION
The Calculation block (Figure 19) allows the User to define and carry out complex mathematical or logical
operations in a single block, reducing the size of the CPL Page. Up to 15 universal inputs are allowed as
variables, and the output may be selected as analog or digital.
Note:
Once the output is chosen and the block is connected, however, the type of output
may NOT be changed unless the connection is first broken.
The Calculation Block has two settings windows, the CPLCalcBlockEditor (Figure 20) is used to create
formulas, and the Descriptor Window is used to name the block.

The CPLCalcBlockEditor Window consists of four text fields. The large field at the top of the page is used to
enter the desired formulas for the block. The three fields at the bottom are Variables, Constants, and Operations:
•
Variables - Variables include V1-V15, and Output. V1-V15 correspond to inputs 1-15.
•
Values are used in comparison equations. Values include Year, Month, Day, Hour, Minute, True,
False, and other common control system considerations.
•
Operations are the mathematical and logical to be made on the variables and constants. Operations
include a comprehensive list of Boolean (AND, OR, NOT, etc.), comparative (Greater Than, Less
Than, Equal, etc.), and mathematical operations (Addition, Subtraction, Square Root, etc.).
To enter values in the CPLCalcBlockEditor:
1.
Use the Output radio button (Figure 21) located above the text fields to select the output type.
2.
The text field in the upper portion of the page is used for entering the equation information. Three

LEAD/LAG
The Lead/Lag Block (Figure 32) uses runtimes of similar HVAC equipment to equalize runtimes on each
machine. This prevents excessive wear and tear on any one machine. It also allows you to set an Interstage
Delay time to prevent multiple pieces of equipment from powering up at the same time and causing excessive
power drain.
The Lead/Lag Blocks supports up to 12 outputs. It accepts up to 12 Runtime inputs. The Lead/Lag block
requires 3 inputs in additional to the Runtime inputs of the equipment. These are:
Control - This value is compared to the setpoints of the Control Points, and activates the outputs
according to the Setpoint and Deadband values selected on the Setting Window.
Enable - When high, allows the Block to begin operating.
Set Sequence - This input is used to lock in the current control time for a specified interval. The
control sequence remains locked in while the Set Sequence input remains high, and then
resets.

The Lead/Lag Block contains both the Settings Window (Figure 33) and the Descriptor Window. On the Settings
Window text fields, you can type in the values requested, or use the spin boxes to select a value.
1.
Enter a number in the Number of Control Points field. This value determines the number of
setpoints the block recognizes, and also the number of outputs available.
2.
Enter a Deadband value. If the value of the control signal reaches the setpoint + or - the half the
deadband, the associated output point will change state. The state of the output depends on:
•
If the block has been defined as direct (default value) or reverse acting (see Step 4 below)
•
Whether the control signal value is rising or falling.
The output state does not change while the value of the control signal remains in the deadband zone.
272
3.
The Interstage Delay interval is the time after a output is initialized that the Block waits before
initializing the next output, preventing excessive power drainage.
4.
The Reverse Acting option causes the output points to energize as the control signal decreases
below the setpoint value. The outputs will deactivate as the control signal rises about the setpoint
value. This is the opposite action of the Direct Acting default setting.
5.
The Control Lowest First option causes the output with the lowest runtime to run first. The default
value is that the output with the highest runtime starts first.

The Ignore Runtime Errors option allows the block to use the last valid runtime inputs if a runtime
input is in error, preventing the entire operation from being halted because of one input error.
7.
The Off Condition menu allows you to select the criteria for how the equipment will be turned off
once the control point value crosses the setpoint:
Runtime - The output with the longest runtime will turn off first.
First On/First Off - The first output to be turned on will be the first output to be turned off.
Last On/First Off - The last output to be turned on will be the first output to be turned off.
8.
Enter the Setpoint value for each output. The Setpoint number corresponds to both the Runtime input
and the output numbers. The number of Setpoints is equal to the number of Control Points.

ENTERING BLOCK INFORMATION - GLOBAL VARIABLES
A Global Variable is a CPL block value from a single control panel that will be accessed frequently on the CPL
Pages for that panel. Global Variables reduce the number of software points needed, and serve as a timesaving
device for creating CPL Pages. They allow the User to save the specified value to a global variable block, and
the global variable block is used thenceforth to represent that value. The value could be data from a single
control point, the result of complex CPL calculations, or any other situation where using a global variable is
faster and easier than using the original CPL block programming.
The Global Variables drop-down menu (Figure 88) has four CPL blocks available to the User:
•
•
GAI (Global Analog Input)
GAO (Global Analog Output)
•
GDI (Global Digital Input)
•
GDO (Global Digital Output)
NexSys allows 100 analog variables and 100 digital variables. As you create each variable, you will assign it an
Index number (1-100). This index number is displayed on each block below the title for easy reference. This
way, a GAO in one location can become a GAI at other locations, provided both analog variables are assigned
the same index number.

SCHEDULING
NexSys provides the User with the capability to create, edit, and reuse energy management schedules. All
scheduling is handled through the FSC (Flexible System Controller) node. Scheduling can also be implemented
using a LonWorks compatible third-party scheduling node. All schedules reside on the node where they were
created. NexSys allows the User to copy schedules from one FSC controller node to another.
Although the completed schedules are stored on the FSC, they must be incorporated into a CPL Page in order to
begin operating. NexSys uses the Schedule CPL Block to implement the schedules. For more information on the
Schedule CPL Block, please see Section Four, Programming - Chapter Three.
THE SCHEDULE SUBTREE
Scheduling allows you to design and implement a customized on/off control program, designed for use on
specific days, seasons, or other criteria. There are two types of data concerning the Schedule information:
•
The Summary Schedule List contains the listing of all the individual schedules on a given panel.
The Schedule list provides a systematic control over the schedules. From the list of schedules, new
schedules can be added and old schedules deleted.
•
The second source of data is the actual schedule(s). The individual schedules have day/time entries.
There are NWS data sources defined to handle this information.
VIEWING INDIVIDUAL SCHEDULES
Schedules are found on the Physical Tree beneath the FSC controller node on which they reside (Figure 1). To
view the available schedules on the Schedules subtree:
1.
Click
to expand the FSC controller node you are working with.
2.
Click

PHYSICAL TREE
The Physical Tree is a representation of the nodes connected on the LON (LONWORKS control networking
technology). Each node contains all the points for the designated hardware device (if available), and also the
LMOs (LONMARK Objects) if the device is LONMARK-compliant. The entire Physical Tree can be collapsed into
the NexSys Network Interface Node, or expanded from this same point.
•
To expand the tree, click
at the node you wish to view. To collapse, click
at the node
you wish to close.
The Physical Tree consists of the system node represented as NexSys Network Interface (Figure 14), controller
nodes, and routers. Figure 15 shows the VAV-01 node on the Physical Tree expanded to display its points, and
corresponding NVs (Network Variables) and CPs (Configuration Parameters) for, in this example, the Node
Object point on the node.
Figure 14. NexSys Network Interface Node
Figure 15. Expanded VAV-01 Node
NEXSYS NETWORK INTERFACE
The NexSys Network Interface node (Figure 14) is the system, or root node for your control system. It represents
the physical interface card to the LONWORKS network (the PCLTA 10/20 or PCC-10 interface card installed on
your PC or laptop). It will always be the first node on the Physical Tree, and is also known as the Global Node.

EDITING THE NEXSYS NETWORK INTERFACE
The NexSys Network Interface uses the Editing: NexSys Network Interface dialog box (Figure 16) to
configure operating properties for your control system. The dialog box displays general information on your
system, as well as text fields for with default values that define interval rates.
Figure 16. Editing NexSys Network Interface Dialog Box
Figure 17. NexSys Network Interface Pop-up Menu
TO ACCESS THE NEXSYS NETWORK INTERFACE EDITOR:
1.
Right click on the NexSys Network Interface node, and select Edit from the pop-up menu (Figure
17).
NEXSYS NETWORK INTERFACE EDITOR OPTIONS:
NSI Timeout (sec) - Indicates how long the system waits for remote LNS clients to respond to a ping.
Discovery Interval (sec) - Contains the new device discovery interval (in seconds) in which LCA Object
Server scans the network for newly attached, unconfigured devices. An interval value of 0 (the
default value) turns off the background discovery process. A value of 65535 means “Do Not
Change”. All other values indicate the minimum interval between discoveries.
Update Interval (sec) - Indicates the interval (in seconds) in which NSS retries updating (in the background) any changes made to devices in the field. A value of 0 indicates that the background process
is turned off. Setting this property to 0 will turn off the background process.
Transmit Timer (sec) - The interval (in seconds) that the LON retries to send Request and Acknowledged
messages.
Register Nodes on Receipt of Service Pin - Tells NexSys to register the node in the database when it
receives a service pin.
Ignore Pending Update - Tells NexSys to ignore any pending updates when receiving the remote client

request to go OnNet, avoiding potential delays due to a large backlog of updates.
OnNet - When this box is checked, you are in OnNet Mode, and are now communicating with the LNS
database and the devices in the field. OnNet Mode is a management mode in which the NSS updates
both its on-board database and the configuration of devices in the network. When the NSS is first
placed in the OnNet mode it also updates any changes made while it was in the OffNet management
mode.
Licensing - Displays the licensing information for your system:
• If you have purchased a Standard LNS License
• The amount of Credits In License equals the amount of devices that can be installed on the
system.
• The Licensed Credits Used is the amount of devices installed in the system.
• Deficit Credits are devices installed that exceed the legal number of credits allowed.
• The Maximum Deficit Credits is the maximum number of devices that you can install during
the Deficit Days Remaining grace period.
• Deficit Days Remaining is the amount of time given by LNS to resolve your licensing deficits
before LNS shuts down completely. LNS will notify you by message screens when you are in
deficit condition.
Channel Delay (Backbone) - The average number of milliseconds required for a packet to get onto the
channel once it has been queued.
CONNECTION DESCRIPTION TEMPLATE (CDT)
The Connection Description Template (CDT) is the template used to define the parameters of a binding. The
CDT determines the type of addressing and message service to be used, timing parameters, use of authentication
and priority slots, etc. The User can create a new template, or modify existing templates.
The CDT uses five different types of Addressing:
Broadcast - Addresses all the nodes in a subnet or domain.
Neuron ID - Refers to a single node by its unique 48-bit ID
Group -
Refers to numbered group of nodes in the system.
Subnet/Node - Refers to a single node by its domain, subnet, or node (DSN) address (assigned when the
network image is sent to the node for the first time).
Turnaround - Used for connections that take place only within a node.
The CDTs created on the NexSys Network Interface node are displayed in the Connection Description Template
List (Figure ). They will also appear in a scrollable Connection Template list in the Bind To Editor for the User
to select when adding a new bind (please see Section XXX for more information on Binding).
To access the CDTs:

Enter values for the following parameters:
Addressing:
Force Unicast - Forces LNS to use DSN (domain/subnet/node) or NID (Neuron ID) addressing
where it would normally use group (or broadcast) addressing.
No broadcast - Tells LNS to fail if there is no other way to address the message besides broadcast.
Fail group to broadcast - Tells LNS to use broadcast addressing if it has trouble using group
addressing.
Always broadcast - Tells LNS to always use broadcast addressing.
Service Types
Service Type Override - Tells LNS that you will choose the service type explicitly rather than
allowing LNS to determine it.
Acknowledged - The message is sent out and acknowledged by the receiver (not to be used for large
group bindings causing failure to received Acknowledge messages.
Unacknowledged repeated - The message is sent out many times to ensure the probability of it
reaching its destination.
Unacknowledged - The message is sent out once.
Request Response - Used only for out-and-back messages (e.g.,. NV polls), not used for binds.
Timing Parameters
Repeat Count Override - Enter a value for the number of times LNS should repeat an unacknowledged-repeated message.
Retry Count Override - Enter a value for the number of times LNS should retry an acknowledged
message if it does not receive an acknowledgment in time.
Transmit Timer Override - Enter a value for the interval rate LNS waits between retries of
acknowledged and request/response messages.
Receive Timer Override - Select a value that tells LNS the time period within which receiving
devices will treat messages from the same source with the same reference ID as
duplicate messages. Repeats of messages using the above service types all use the
same reference ID as the original to identify them as duplicates.
Repeat Timer Override - Select a value for the interval LNS waits between repeats for unacknowledged-repeated messages.
Other
Authentication Override - Manually overrides control of the LNS message Authentification option.
Use Authentication - Turns the message Authentication option on, telling NexSys to begin sending
and receiving
authentification packets for messages on the network.
Priority Override - Manually overrides control of the LNS message Priority Override option.
Use Priority - Tells LNS that the binding should use a reserved time slot on the network,
helping the message to arrive more quickly to its destination.

333
Workstation Basics
NexSys Workstation User’s Guide
Rev 2.0
A router (Figure 32) is a device that forwards information from one network/subnetwork to another using an
established protocol. Routers do not normally store messages that they are routing. Routers receive a message
and make a decision as to whether the message needs to be forwarded, and if so, to whom. You can also use
routers for network traffic control and for partitioning sections of the network traffic from traffic in other
sections, increasing the efficiency of your network.
A router may be one of four general types: bridge; repeater; configured; and a learning router.
•
A bridge router filters by domain ID only.
•
A repeater router forwards all messages, without any filter at all. It makes no decisions at all, it
simply receives a signal at one end, and broadcasts it out the other. It has limited capability to restore
weak signals to their former power level.
•
A configured router filters messages by domain, subnet, node, or group using configured tables
supplied by the network management tool.
•
A learning router also filters by domain subnet, node or group. The router starts out initially as a
bridge router, and increases the level of filtering as it learns the topology. Learning routers can fail if
configured devices are incorrectly moved within the network.
CONTROLLER NODES
Controller nodes (Figure 32) are hardware devices that actually perform a control or support function. These
devices are intelligent devices that can communicate with other devices on the LONWORKS network, using
LonTalk protocol over one or more communication channels (the path between devices). Each device has a
microprocessor that provides the intelligence, and implements the protocol. The device publishes information
specific to its application, and the protocol defines the format of the messages being sent and received. The
device uses a transceiver installed in the circuitry to electrically interface to the communication channel. All
devices connected to a specific channel must have compatible transceivers with compatible configuration.
Each controller node is configured with a Configuration Data Set (CDS). A CDS is a set of configuration
parameter values associated a particular device template. Third-party devices require a manufacturer plug-in
providing the CDS for the device. Each node pop-up menu has two different commands available for selecting
the CDS:
•
The user can select the default CDS or use any other CDSs that are available for that device with the
Setup Node command.
•
The Config. Data Set command allows the user to add a new CDS, or to apply an existing one.

POINTS
A node is a controller in the field, and the Physical Tree displays an element representing that device. Each
controller node on the Physical Tree, when expanded, displays a list of its points and LMOs (Figure 61).
A Point is a single element of data in the system. Points can be:
•
Hardware (a physical point with an actual value)
•
Software (data bound in by software, often by a CPL program).
•
Analog or digital
•
Inputs (network variable inputs, or NVIs) or outputs (network variable outputs, or NVOs).
•
Points can be predefined on the device, as for ASCs, or can be set up by the User, as with FSCs and
FLCs.

LMOS (LONMARK OBJECTS)
LMOs ( LONMARK Objects) are a collection of network variables, configuration properties, and associated
behaviors defined by Echelon’s LONMARK functional profiles. These functional profiles, as well as the interface
to application programs, are implemented as LONMARK objects on individual devices (Figure 67).
LONMARK objects define standard formats and semantics for how information is exchanged between devices on a
network. Object definitions contain both mandatory and optional network variables and configuration properties,
and may also contain manufacturer-specific network variables and configuration properties.
Figure 67. Expanded LMOs Subtree
Figure 68. NVs List of NVOs And NVIs
NETWORK VARIABLES
Points consist of network variables (NVs). A network variable (NV) is a data item that a device uses to communicate with other devices on the network. Network variables are used in networked control systems because they
eliminate all of the low-level and tedious work of building and sending downlink messages, and receiving and
responding to uplink messages.
•
An NVI (network variable input) is a data item (NV) that the device expects to get from other
devices on the network.
•
An NVO (network variable output) is a data item (NV) that the device expects to provide to other
devices on the network. Use to communicate with one another.
The application specific to that device determines the types, functions, and number of network variables in each
node. Expand the NV to view its NVOs and NVIs (Figure 68)

BINDING: CONNECTING NVOs TO NVIs
Binding is a process that configures the device firmware to know the logical address of the other devices that it
will be sending NVO data to and receiving NVI data from. A bind, also referred to as a connection, creates
logical connections between the NVO of the selected device to the NVI of the other device(s) on the network it
is communicating with. Binding is handled through the Binding Editor (Figure 69). For more information on
Binding, please see Section Four, Programming - Chapter One.
NexSys uses the Connection Description Template (CDT) to define the parameters of a bind. The CDT will
include information on what sort of addressing and message service type it should use, timing parameters, use of
authentication and priority slots, etc. Please see NexSys Network Interface - Connection Description Templates in this chapter for more information on CDTs.
CONFIGURATION PROPERTIES
When a network variable (NV) is expanded (Figure 70), it displays the list of its configuration properties (CPs).
Configuration properties are data values used to modify the operation of a device or LONMARK object. They
may belong to a device, a LONMARK object, or an NV (Network Variable). Configuration properties may be
implemented using configuration network variables, a configuration file, or in a direct memory access data
block.
There are two types of configuration property types: Standard Configuration Property Types (SCPTs, called
“skip-its), and User-defined Configured Property Types (UCPTs, called “you-keep-its). UCPTs are generally
given a descriptive name by the User.

354
Operations

Workstation Basics
allows you to set up your trend to perform a variety of functions. When a trend has been configured, NexSys
initiates the trending function as soon as the selected controller begins running. The results of the Trend Setup
are displayed in the Trend Harvest Panel section immediately following.
NOTE: Trending data for ASCs is stored in their internal volatile memory, and is not preserved
across a power loss or other conditions. If the data is critical, then it should be transferred
to the FSC or other means of permanent storage.
Figure 99. Trend Setup Panel
You can select from three types of trending: Interval, Delta, or a Hybrid of these two.
Interval Trending: Interval Trending has its primary emphasis in logging data on a time interval basis, and is
very useful for determining system timing. NWS logs the data you have requested at the configured time interval
whether or not the data has changed, and results in a very equally spaced graph of data points (see Trend Harvest
Panel).
Delta Trending: Delta Trending has its emphasis in the change of an analog point. Use Delta Trending when
you wish to trend a temperature for an extended period of time, but are interested only in a certain increment of
change. Stable data can be stored for long periods of time. Delta Trending is often used for tracking space
temperature changes during both occupied and unoccupied modes. It results in a Trend Harvest Panel graph of
unequally spaced data, with little detail of what happened between changes (see Trend Harvest Panel following
this section ).
Hybrid Trending: You can use a mix of both Interval and Delta Trending in any way desired. A trend can be
declared that gathers data at a specified interval, and at a specified delta. Hybrid Trending provides a middle
ground between the two strategies, and is used when you want periodic data gathered, but also want to note
changes.
TREND DURING OCCUPANCY
This mechanism is based on the status of a digital point. The Trend During Occupancy option (Figure 100)
allows the controller to disable trending when activity is not of interest to the controller.
•
The ASCs will allow Occupancy to be the only digital value for trending enable/disable. When this
option is selected, the ASC will trend when the controller is Occupied, and not trend when the
controller is Unoccupied.
•
The FSC will allow trending to occur on any digital point value that exists locally on the controller
(Figure 101). The status of this digital point can be determined on a different controller, but that point
must be mapped to the FSC selected and bound between the controllers. The FSC will trend when the
selected state is True. If Trend during occupancy is selected, the controller trends only when the
selected State is true and the mode is Occupied.

SAMPLING
A sample is the data gathered on a point at the specified interval/delta. A finite amount of samples is available in
the buffer for each node. Each point to be sampled is assigned a trend channel. The number of trend channel
available is device dependent. You can designate how many samples you want allocated to each trend channel if
you are sampling multiple points. If you are only sampling one point per node, the entire sample amount will
default to that point. The memory allocation is as follows:

•
Number of Trend Channels = 6
•
Total Number of Samples = 880

•
Number of Trend Channels = 100
•
Total Number of Samples = 5000

TREND SETUP FOR FSCS
NexSys provides several features for trending on FSCs that are not available on ASCs:
•
The FSC will allow trending to occur on any digital point value that exists locally on the controller.
The status of this digital point can be determined on a different controller, but that point must be
mapped to the FSC selected and bound between the controllers (see Enable on Digital, above).
•
A start and stop time interval can be provided in the configuration data for the trend channel. This
time interval determines when the trending is enabled (greater than or equal to the first time) and
disabled (greater than or equal to the second time). The time can wrap around midnight (for example,
it can be enabled at 7:00 PM and disabled at 7:30 am).
The Trend Setup Panel for the FSC is configured in the manner as for ASCs, with the addition of the Time Based
Start and Stop fields, and Enable Point State field.
To configure a Time Based trend:
1.
Left click on the Time Based check box (Figure 106). A check will appear, and the Start and Stop
fields will become active.

SNVTS
Standard Network Variable Types (SNVTs) provide inter-operability between devices made by different
manufacturers by providing a well-defined interface for communication .
Standard Network Variable Types (SNVTs) allow these devices to inter-operate using networks variables (NVs)
by structuring the NV data so that all data is interpreted in the same way.
DIGITAL POINTS AND SNVTS
The User can select SNVT types (Figure 1) when adding a point to the FSC. The types of SNVTs available
depends on the type of digital point being added. When adding digital points:
•
Digital points are:
Input or output
hardware or software.
Output hardware points are:
Momentary
Maintained.
•
Hardware points must be assigned to an I/O module and point on the module.
•
The same SNVTs are available to all the digital points.

GLOSSARY
A
Acknowledged Messaging - Provides end-to-end acknowledgment, where a message is sent to each designated
receiver, and the sender expects to receive an acknowledgment message from each. If the send does not receive
an acknowledgment, it times out and retries the transaction at the end of the Transaction Timer interval.
Action: Reverse/Direct. - See Direction Reverse.
Active Alarm Window - Displays only the current or unacknowledged alarms in the NexSys system.
Active X Control - A 32-bit, language-independent programmable objects that can be used in a variety of
software development tools.
Address Table Entry - Used with point binding, the address table entry tells the NV sending the data the
address to send to, and sometimes also telling the receiver where the data is being sent.
AI - Analog Input.
AHU - Air Handling Unit.
Alarm History window - Gives the history of all alarms from all nodes as they are sent to the NWS.
Alarm Hysteresis - The range an item in alarm must pass in order to generate a return to normal.
Alarm Inhibit Time - The length of time - in hours, minutes, and seconds- that must elapse, after the controller
is activated, before an alarm is generated for a particular point. This prevents unwanted alarms on start-up or
when the controller is powered up.
Alarm Set Time - The length of time - in hours, minutes, and seconds- a point must be in alarm state before it is
broadcast.
Alarm Type - You may define an alarm for certain points. Only one alarm type may be defined for each point,
but that type may apply to as many of that point’s states as you wish. You also have the option of selecting one
of several Alarm Types to make the alarm more descriptive.
Alias - An alternative name for an object, such as a variable, file, or device. The alias increases binding flexibility by allowing an NV (Network Variable) to use more than one selector and/or address table entry.
Analog - Point data which has a numerical value. (e.g. 35°F, 10 minutes, 1000 CFM)
AO - Analog Output.
ASC - Application Specific Controller.

Glossary
Configuration Data Set (CDS) - A set of configuration parameter values associated with a particular device
template. The user can choose to use the default values, or use a different set of values available for the template.
CDSs allow a user to save a set of values for a particular setup of a type of device, and apply it to other similar
devices of the same type.
Configuration Properties (CPs) - Configuration properties are data values used to configure the operation of a
device or LONMARK object. Configuration properties may be implemented using configuration network variables, or they may be implemented as configuration parameters stored in a data block.
Connection Description Template (CDT) - Defines the parameters of a bind (also referred to as a connection).
The CDT will include information on what sort of addressing and message service type it should use, timing
parameters, use of authentication and priority slots, etc.
Continuous Fan - An HVAC fan which runs continually during Occupied Mode.
CPL - NexSys’s Control Programming Language.
D
DA - Discharge Air.
DAT - Discharge Air Temperature.
Data Server - An engine for system monitoring and control, it interfaces with the LNS Server to automatically
monitor network data points. It also converts network data in binary data or formatted strings for direct display.
Deadband - Range an input variable may pass through without initiating any change in the output variable.
Default Gateway - A network card (router) at the end of a local trunk allowing access to a remote host.
Default Value - A value in SNVT units of the point used in such specific instances as Send Default on Error and
Override Behavior. This is also used as the initial value at start-up if the point is not fixed.
Delta Send - Increment by which an AI must change before sending its status to the LON.
DHCP - Dynamic Host Configuration Protocol. A method of assigning IP addresses to client PCs on a network
which doesn’t use static IP addresses.
DI - Digital Input or Discrete Input.
Dial Provider - The FSC at a remote side, connected via NCB, which has the responsibility for monitoring that
site and dialing the main system if an alarm occurs.
Digital - Traditionally, point data which can have one of two states. (e.g. off/on, open/closed, true/false.) On
occasion, a digital point with a feedback will have three states. (e.g. on/off/auto). In the NWS, however, a
digital point can have several “integer” states. For example, the HVAC mode SNVT has eight modes or states.
Digital Lockout - Prevents unwanted alarms by locking out alarms from a point. Once you select a Digital
Lockout point, you must specify the lockout state and time (if desired). This is commonly done with temperature sensors in conditioned spaces so that they do not generate nuisance alarms when the conditioning equipment
is not active.
Digital Lockout Point - DO points whose status dictates whether alarms should be generated for a particular AI.
Digital Lockout State - States of DO Lockout Point for which AI alarms are to be locked out.
Digital Lockout Time - The time - in hours, minutes, and seconds- that must elapse after a DO switches from a
digital lockout state to a non-digital lockout state before alarms can be generated on a particular AI. This
prevents unwanted alarms from being generated on the AI the first few moments after a DO changes out of a
Digital Lockout State.
Direction Reverse - If you select YES, this parameter reverses increment/decrement points. (Note: On an I/O
Module page, the increment/decrement points are reversed when you select YES. Therefore, instead of using
this function to correct an error, you may want to switch the increment/decrement I/O Module point preferences.) For DO hardware points and discrete hardware points, this is called Action: Reverse/Direct.
Discovery Interval - Indicates the minimum interval rate (in seconds) at which the LCA Object Server scans
the network for newly attached, unconfigured devices.
DNS - Domain Name System. A method for resolving host names and IP addresses used in the Internet.

M
MA - Mixed Air. The combined outside air and recirculated air.
MAC Address - Media Access Control Address. A unique alphanumeric code found on a Network Interface
Card, also known as the hardware address.
MAI - Multiple Analog Input. A point type allowing the user to get information from a number of analog points
in the system without using a large number of points on the FSC when the user is not concerned about which
specific controller the value comes from. MAI points have no point status. They are reported in CPL only.
MAIs may be used for such things as finding the average space temperature from a group of sensors, or finding
the minimum/maximum thermal load from a group of VAV controllers in order to control an AHU’s output.
Maintenance Time - The time - in hours, minutes, and seconds- in which the actuator will be driven an extra
amount at its endpoints to ensure that it reaches the endpoint. Since a floating actuator has no feedback, this is
the primary way it can be automatically re-zeroed, whenever it is sent to one extreme or the other. This applies
to the FSC only. Normally, this will be set at 1.5 times the drive time.
Max Receive Time - See NV Update Time.
Max Send Time - The maximum time - in hours, minutes, and seconds- that will elapse between status broadcasts of a particular point, regardless of whether or not it has changed value. This ensures occasional updates in
case the change of state broadcast was missed. NV updates are broadcast to bound connections only, not to the
front end.
Max Value - Maximum value the point’s status can be. If the point is commanded above the Max Value, its
status will be equal to the Max Value. For hardware analog points, this is the value that matches the field max
value in engineering units.
MDI - Multiple Discrete Input. A point type allowing the user to get information from a number of discrete
points in the system without using a large number of discrete points on the FSC when the user is not concerned
about which specific controller the value comes from. MDI points have no point status. They are reported in
the CPL only. MDIs may be used for such things as monitoring the number of AHU requests from a set of VAV
controllers so that the FSC can decide whether to turn on.
Min Delta - The minimum change that must occur in a particular analog point for it to be broadcast. Used to
limit network traffic. The Min Delta must be valid for a broadcast to occur.
Minimum Move - The time - in hours, minutes, and seconds- that constitutes the minimum move that will be
imposed on the floating actuator. This prevents minor back-and-forth hunting or tiny moves which causes wear
and tear on an actuator without improving control.
Min Send Time - The minimum time - in hours, minutes, and seconds- that must elapse between status broadcasts of a particular point, regardless of how often its value changes. This is used to limit network traffic,
especially on a point that may change frequently. The send time must be valid for a broadcast to occur. Analog
points do not broadcast to the front end for any reason but alarms.
Min Value - The minimum value a point’s status can be. If a point is commanded below the minimum value, its
status will be equal to the Min Value. For hardware analog points, this is the values that matches the field Min
Value. The value is in the engineering units of the appropriate SNVT.
MIP - Microprocessor Interface Program.

OVERVIEW OF NEXSYS AND LNS ARCHITECTURE
NexSys 2.0 contains two ESUSA software programs that interact directly with LNS. These are the NexSys
Workstation (NWS), and LNServer. LNS architecture consists of Network Services Server (NSS), Network
Services Interface (NSI), and LONWORKS Component Architecture (LCA) Object Server Active X Control.
NWS is the user interface, and LNServer processes information for the NWS. LNS relays field information to
and from LNServer, and stores information in the database. LNS can be configured as a server with both NSS
and NSI installed, or as a client, which has neither. The LCA Object Server Active X Control enables communication between NWS and LNS.
While NexSys 2.0 has all the functionality of previous NexSys versions, it is fundamentally different because it
uses LONWORKS® Network Services (LNS) 3.0 Architecture as a network management tool. LNS allows software
tools from different vendors to work together on a network. Users see the NexSys Workstation (NWS) graphical
user interface, but LNS core services are transparent to the user. The LNS architecture exists as an underlying
framework, providing installation, configuration, and maintenance services, as well as node monitoring and
control. Figure 1 illustrates the relationship between NexSys and the LNS architecture on both main and remote
PCs.

NEXSYS SOFTWARE
NexSys 2.0 contains two ESUSA software programs; the NexSys Workstation (NWS), and LNServer. NWS
provides the capability to configure, edit, and program your building control system. LNServer provides access
to the LNS architecture, and gives NexSys the ability to interact with Active X component-based software.
NEXSYS WORKSTATION (NWS)
NexSys Workstation (NWS) is the graphical component of NexSys. This is the NexSys User Interface (UI), and
allows the user to view and work with information regarding the nodes on the system, set up Control Programming Language (CPL) programs, use schedules, set up graphical representations of the building system, etc.

NexSys Architecture
LNSERVER
LNServer connects NWS to LNS. When a request is made, the LNServer communicates with the LONWORKS
Component Architecture (LCA) Object Server Active X Control, which in turn passes the request to LNS. The
LNServer runs concurrent with the NexSys Workstation.
The LNServer performs the functions of the Echsub and the Netman in previous versions of NexSys, and uses
LNS instead of LonManager™ API for DOS. Unlike previous versions of the EchSub and the NetMan, a copy
of LNServer must be installed on every PC; both main and remote.
LNS 3.0 ARCHITECTURE
LNS architecture has two main components: Network Services Server (NSS) and Network Services Interface
(NSI). NSS provides network management services. It communicates with the field via the LONWORKS interface
card (NSI). NSS and NSI operations are transparent to the user. The LONWORKS Component Architecture (LCA)
Object Server Active X Control provides a programming language-independent interface to LNS.
LNS uses a client/server model. With LNS, the user can setup, configure, or manage the network from any point,
using a variety of tools. LNS automatically performs many networking tasks, including detection of new nodes
and automatic notification of address changes. LNS continually updates all user interfaces that monitor and
control nodes.
All Echelon LNS software is automatically installed during the NexSys installation. The main system will have
the Network Services Server (NSS), the network databases, and the LonTalk interface card. Remote systems will
only an LNS client.
LCA OBJECT SERVER ACTIVEX CONTROL
The LONWORKS Component Architecture (LCA) Object Server is an ActiveX control that converts LNS objects
(e.g., devices, routers, channels) managed by the NSS for Windows engine into standard OLE objects. The
object server also provides a network tool kernel that enables sharing of information and objects between
multiple tools and components.
Echelon’s LONWORKS Component Architecture (LCA) Object Server is installed on each NexSys PC to communicate with the Network Services Server (NSS).
NETWORK SERVICES SERVER (NSS)
The Network Services Server (NSS) is the LNS network management service. It processes the data, maintains
the network database, and executes the services requested by the clients from the various points of system
access. Each NexSys system will have ONLY one NSS, and it will be located in the main NexSys PC. All IP
remote PCs and network tools communicate with the main PC’s NSS via TCP/IP. Individual clients on the
network may monitor the network, but all changes must be made through the single NSS.
The NSS communicates with LNServer (and ultimately, NWS) through the LCA Object Server Active X
Control. NSS communicates with devices in the field through the NSI ( see below).
NETWORK SERVICES INTERFACE (NSI)
Information is passed to the field network from the NSS through the Network Services Interface (NSI) card. The
Network Services Interface (NSI) is the hardware interface card in the main NexSys PC. This interface card is
either the PCLTA-10, the PCLTA-20, or the PCC-10. The only NSI is located in the main NexSys PC. Remote
PCs communicate via TCP/IP with the NSS on the main NexSys PC.
EXAMPLE OF NEXSYS SOFTWARE INTERACTION
ESUSA’s NexSys Workstation (NWS), ESUSA’s LNServer, and the Echelon LNS components work together to
make up NexSys 2.0. The NWS allows the user to visually interface with their environmental control system.

They can view, enter, or update information on their nodes and points, CPL programs, schedules, and binding
information. LNServer and LNS manage services carried out by the user requests.
In this example, the user creates a new node. LNServer then communicates this request to LNS through the LCA
Object Server. The NSS creates or accesses the network database for the information entered in the NWS. The
NSS is also communicating with the device in the field through the NSI card.
When a VAV-01 node is added to the Physical Tree through the NWS, All the information regarding that VAV
must be downloaded to the actual controller in the field. The interactions listed below take place in the order as
defined. :
1.
User adds VAV-01 node to the Physical Tree in NWS.
2.
NWS requests service pin from LNServer. User send service pin from the device in the field,
bypassing the LNS database.
3.
NWS sends Neuron ID from LNServer, which passes the data to the LNS database.
4.
NWS commands that the Network Image and Configuration Data be downloaded to the VAV-01 in
the field. The data is routed through LNServer to LNS, and then downloaded to the device. A
“Finished” message is sent back from the device to NWS.
Figure 2 below illustrates the software interactions described above:

OVERVIEW OF LNSERVER
LNServer connects NWS to LNS. When a request is made, the LNServer communicates with the LONWORKS
Component Architecture (LCA) Object Server Active X Control, which in turn passes the request to LNS. The
LNServer runs concurrent with the NexSys Workstation.
The LNServer performs the functions of the Echsub and the Netman in previous versions of NexSys, and uses
LNS instead of LonManager™ API for DOS. Unlike previous versions of the EchSub and the NetMan, a copy
of LNServer must be installed on every PC; both main and remote.
STARTING LNSERVER
1.
Double Click on
LNServer icon OR:
2.
Click
> Programs >NexSys 2.0 Main System > LNServer OR:
3.
Click
> Programs > NexSys2 Start. This option will open both LNServer and NWS.
The LNServer Main Window (Figure 1) consists of four windows; a large window on the left, and three smaller
windows on the right.
•
When LNServer first opens, only the LNServer Messages and the UI Activity windows appear.
•
When the Tree Poll Thread window opens, the LNServer is now operational, and you can now start
NWS. The User Connection Window will remain blank until NWS is running.
