Overview
Quick Start
When OneSix is run for the first time it displays this help screen. You may view this
help screen again by selecting "Help" from OneSix's main window.
OneSix is designed to gather data from sensors. OneSix makes available the data it
receives from each sensor through OPC tags.
The Main OneSix™ Server window will show the total number of devices in the
startup list and how many of those that are online. The offline devices will be shown
in the list box at the bottom of the window.
OneSix™ can be a stand-alone data logger. When data logging is enabled, OneSix™
will store collected data in an ASCII file at a programmable interval. See section
"OneSix Server Data Logging".
This Help and all other Help topics may be accessed from the main window by
selecting Help or pressing F1.

OneSix Server Help
Start OneSix.
When the "Add Wireless Device" screen appears, press the service
mode button on your transmitter to transmit a packet that OneSix can
see.
When a device appears in the window, you may click to select it and
then press the 'Edit' button to change its label name and transmit time.
Press OK to add these sensors to the OneSix list
OneSixOPC will create OPC tag objects for each device and start
polling and gathering data from each device.
Overview x 1
Description
If there is not an OneSixOPC.ini file or if [Server]NumberDevices=0 and when
OneSix™ starts, it will automatically prompt for devices on the network and add them
to its list of devices to process.
OneSix™ is a data acquisition OLE for Process Control (OPC) server that acquires
data from devices and passes this data using OPC to a client application. OneSix
waits for the device to transmit and then processes the transmission.
Any Windows® application that can use OPC can obtain this data from the
OneSix™Server. Examples of such applications include Wonderware® Intouch,
National Instruments® LookOut, and general development applications like
Microsoft® Visual Basic and Borland® Delphi.
OneSix™can be a stand-alone data logger. When data logging is enabled,
OneSix™will also store collected data in an ASCII file at a programmable interval.
Another program such as a spreadsheet or a database manager can import the data.
See section "OneSix Server Data Logging".
OneSix Server can receive transmissions from wireless devices such as the wireless
temperature transmitter. Other devices include the wireless humidity sensor and
wireless analog input. OneSix uses a wireless receiver such as the Point Repeater,
the Point Host or the PointView Receiver to receive transmissions from wireless
sensors. OneSix can also use multiple TCP/IP Receivers (Point Managers in PassThru mode) to receive data through TCP/IP connection.
When setting up a wireless network, OneSix passively waits for transmissions instead
of actively polling for devices. This can make the acquisition of sensors take a
longer time than for a wired network as OneSix must wait for the device to transmit.
You can speed up this process by pressing the service button on the device so that it
transmits while you are in the “Add Sensors” screen.
Each device has an entry in the device's INI file section. Each device has a
"repeateraddress" attribute. When running OneSix with a Point Repeater, the
Repeater ID is stored in the "repeateraddress" entry. The value in the
"repeateraddress" indicates which Point Repeater sent the sensor information With
all other wireless receivers, the "repeateraddress" is set to 0. Finally, the INI entry
and OPC tag "Polltime" for each device has a different meaning when working with
wireless transmitters. OneSix cannot poll the wireless sensors. It must wait for a
transmission. Therefore, OneSix uses polltime to estimate how frequently a
transmission should come from a device. It also uses a multipler of this time to
determine if a device is offline. This multipler is configurable by the user.
Setup Described
OneSix will display the “Add Sensors” screen when it starts for the first time. The
setup screen is the method by which OneSix acquires wireless devices. The default
on the setup screen is to accept only packets that are sent in service mode from the
device (the packet is sent by pressing the service button on the device.) To change
this default, uncheck the "Service Mode Only" checkbox. OneSix will then display
all the packets it receives. When OneSix receives a packet from a device new to it, it
names the device following the naming conventions detailed below, and it displays
the device's name and serial number in the window.
You have several options after the device has been displayed. The "Clear New"
button will clear all the devices that have just been received. The "Delete" button
2 x Overview
OneSix Server Help
will delete a single device. Click on a device to select it and click on "Delete" to
delete it. To edit a device click on the device to select it and click on "Edit" to edit
the device. There is also a "Stop" button. If you click that button, OneSix will stop
listing devices in the window. When you click on the "Stop" button it becomes a
"Receive" button. If you click on that, OneSix will start receiving packets and listing
devices again.
When you are ready, hit "OK", or "Cancel" to exit.
Edit Device
The Edit screen for a new wireless device shows the device's serial number, which
the user cannot change, the device's current Label, which can be changed by the
user, and the Transmit Rate for the device. The Label cannot be the same as the label
used by any current device. The Transmit Rate is in seconds. The default value is
60. OneSix uses the Transmit Rate to determine if a device has gone offline.
Receivers
The following is a list of the receivers that OneSix can use:

Device List
OneSix™ Server interfaces to a large number of devices. New devices are
continually being created for the Wireless network. Check with your distributor for
the latest.
The following is a list of devices supported by OneSix™ Server:
Point Sensor Temperat ure
Point Sensor Temp/Humidity
Point Sensor Analog 5V
Point Sensor Analog 10V
Point Sensor Analog 20mA
Point Probe
Point Sensor Pressure
Point Sensor DSCI
Point Sensor IR Counter
Point Sensor Thermistor
Point Sensor Counter Temperature
Point Sensor Fast Counter Temperature
Point Sensor Alarm Temperature
Point Access/Control Reader
Point Directional Counter
Point Dual Discrete Output
Point Analog Output
Polling
The polltime has a slightly different meaning for wireless sensors. OneSix does not
actively poll wireless devices. Rather, it waits to receive a packet from the devices.
Therefore, the polltime is how often OneSix expects to receive a packet from the
wireless devices.
The polltime for a wireless device is configurable during device setup. OneSix will
use this time to determine when to mark a device offline. OneSix has a INI file
parameter called "Tries" that sets how long a device has to transmit before it is
considered offline. For example, if the device has a polltime of 1 minute, and
OneSix has "tries" set to 3, then OneSix will consider the device offline if it does not
receive a packet from that device in 3 minutes ("tries" times "polltime").
Identification
4 x Overview
OneSix™ identifies each device with a unique label name. A client application uses
this label (an OPC topic) to obtain data from the server.
OneSix Server Help
Filtering
For both analog and temperature devices, OneSix™ allows the user to define a
deadband to control the amount of change that must occur before the server updates a
Client with new data. Deadband is useful to control the amount of information that is
passed through OPC to the client application. For analog devices, the deadband is
entered as the percentage of full scale of Engineering units. For temperature devices,
the deadband is entered in degrees C.
Also for both analog and temperature devices, One Six™ provides the means to filter
the data with either an Average, Median or combination Median Average filter
before either logging data or delivering data through OPC. In the One Six INI file,
you specify the filter type and the number of samples to filter.
What is OPC?
Data Logging
OLE for Process Control (OPC) is a specific specification of Microsoft’s Object
Linking and Embeddeding (OLE) and Component Object Model (COM) that is
administered by the OPC Foundation (150 member companies including Microsoft
Corporation). OPC provides a common interface for devices and applications to
communicate. Devices that gather or originate data become OPC servers, providing
data to OPC client applications in a consistent fashion. At the heart of OPC is the
client/server model in which the OPC server provides and interface to the OPC
object, allowing client applications to control devices and manage device data in a
generic fashion. OPC servers can be accessed through most HMI software and
through a variety of languages, including C++, Visual Basic, and Delphi. The OPC
server collects data from physical devices for distribution to OPC client applications
and also has the responsibility for updating device data when an OPC client issues a
write.
An OPC client connects to and communicates with an OPC server through one of two
interfaces defined in the OPC specification. The OLE automation interface allows
users to access data through the use of a common, easily understood scripting
language. The COM interface is more complex, but provides finer levels of control
and flexibility for developers and users proficient in languages such as C or C++.
OPC client applications can access OPC servers locally within a computer or from a
networked server.
OneSix™ Server can log data to an ASCII file at a programmable interval. The
default name of the file is ONESIX.LOG.
A client application can control logging through OPC variables. The client can
start/stop logging or just log a single record.
For diagnostic purposes, OneSix™ can log errors that have occurred while waiting
or process device data.
For more information see the section OneSix Server Data Logging.

Main Window
Setup
OneSix™ displays the number of devices online and offline. It also lists the devices
that are currently offline displaying the name and serial number of the device. If
OneSix™ is running with TCP/IP receivers, then for each offline device it will
display the node address, name and serial number of the device.
OneSix™ simplifies setup by automatically finding, identifying and beginning to poll
devices in a network. OneSix™ assumes default initial values. You can easily change
these values by editing the ONESIXOPC.INI file with an ASCII text editor. (The
installation program for OneSix™ Server created a short cut to the ONESIXOPC.INI
file. Double clicking will automatically start WordPad or Notepad.) See the section
"OneSix Server .INI File Format".
Change Port
The Change Port submenu allows you to switch to another wireless receiver port.
When the Change Port submenu is selected, OneSix™ displays the Select
Communication Port window. Choose one of the following:
AUTO - instructs OneSix™ to search Port Numbers 1 to 4 for the
PointView Receiver.
PointView Receiver
Point Host
TZR Transceiver – (Point Transceiver) – make sure the TZR baud rate is
set to 19200.
TCP/IP Receiver – uses a receiver that uses the TCP/IP protocol to receive
sensor packet data. (Point Manager in “pass-thru” mode).
When OK is clicked, OneSix™ tries to initialize the port. For the PointView and
TCP/IP Receivers, OneSix confirms that the receiver is present. For the Point Host
and the TZR Transceiver, OneSix assumes the receiver is present. If OneSix™ fails,
OneSix™ displays the OneSix Initializing Error Window allowing you to retry, select
another port or exit OneSix™. If OneSix™ succeeds, OneSix™ starts listening and
processing sensor packets.

Outputs
OneSix can send output packets to output devices. (Normally sensors do not receive
packets) Output devices must be setup manually. Some Outputs need to be “trained”
to the packets that it will receive for from the Server.
New and Edit
Create or edit an Output object to manage an Output sensor. The following
describe the parameters necessary to set up an Output sensor.
Type – “Dual Discrete Outputs” or “12 bit Analog Output”. Select the type
of Output sensor. Note changeable only for the Edit Output window.
Serial Number – Some Outputs sensors can “learn” a serial number. Others
have the serial number preassigned and must be entered in the field.
These sensors have the serial number labeled. For those sensors that
must learn their serial number, OneSix creates a default serial number.
Press the “Generate New Serial Number” button to generate a new
serial number.
Label – name assigned for this Output sensor. The label name is used for
the OPC topic name. This name must be unique. For the Edit Window,
the Label field contains a list box. Select the Output to modify from the
list. You can also change the label for the current Output.
Node – This field applies only when using the TCP/IP Receiver. The Node
List box contains a list of the TCP/IP Receivers to send the output
packet to. For the “Send All” selection, OneSix will send the packet to
all the TCP/IP Receivers.
Dual Discrete Outputs
Send when output B is written – If checked, OneSix will only send the
output packet only when the “outputB” item is written to. Output A is
first written to and the output B. If unchecked, OneSix will send the
output packet when either the “outputA” or “outputB” items are written
to. The state both outputs are sent in the same packet.
12 bit Analog Output
Scale – the scale to apply to the raw reading (12 bits: 0 to 4095).
Offset – the offset to apply to the reading after the scale is applied.
Engeering Value = Scale * raw + Offset.
Train
Units – units label for the analog output.
The Train dialog is used in the processing of training the Output device to output
packets (as produced by OneSix). Follow these steps to train an Output device:
1. Select the desired Output from the list of Outputs.
2. Press and hold the button on the Output device (label as “train”).
3. Click the button on the Train window. Repeat until the LED on the
Output device is on.

OneSix INI Backup
Any time One Six Server modifies the INI file, One Six will create a copy of the
previous INI file. OneSix Server names this backup file the same file name as the
INI file but names the file extension as “.Bnn” where n is from 01 to 20. One Six
will create up to 20 backups. If One Six needs to create more, it will overwrite the
oldest backup which will be typically starting at “.B01”.
If you need to revert to a backup just rename the original ONESIXOPC.INI file and
then rename the backup to ONESIXOPC.INI.

OneSix™ uses the device name as the first part of the OPC tag name. A device
contains a nodal address. When "Search and Add Devices" is selected from setup,
OneSix™ Server will automatically assign label names that will be used as part of the
OPC tag name for each new device found. The user can then change the name if they
choose.

OneSix Server Data Logging
Features
OneSix™ Server can log data to an ASCII file at a programmable interval. The
default name of the file is ONESIX.LOG. The name can be changed by changing the
INI file. The log rate (programmable interval) can be changed in the INI file
([Logging] LogRate=) or by a client application through OPC (SERVER!LogRate).
By default, all devices listed in the INI file are logged. You can disable logging for
each device ([Devicen] Log=). The number of decimal places logged for each
device can be changed as well ([Devicen] LogDecimalPlaces=). When a device is
offline, OneSix™ uses the last value gathered when online for logging. If the device
has never been online, then -999999.0 is logged. You can have OneSix™ place a
character such as '*' or a string such as 'offline' in the logging string instead of the last
value([Logging] OfflineIndicator=). All these parameters can be changed in the INI
file.
A client application can control logging through OPC variables. The client can
start/stop logging or just log a single record. You can have your client application
synchronize logging by keying off of one of the device's OPC variable changing
values and then have OneSix™ log one record. The client can also control the log
rate. The full path name of the log file is also available to a client application
through OPC. See the section "OPC Server Items" for more information.
For diagnostic purposes, OneSix™ can log errors that have occurred while waiting
and processing data from the sensors. This feature is enabled in the INI file
([Logging] LogErrors=). OneSix™ places the errors in a file called ONESIX.ERR.
See the section "ONESIXOPC.INI: Logging” for more information.
44 x OneSix Server Data Logging
OneSix Server Help
File Management
If the log rate is greater than or equal to 5 seconds, OneSix™ opens and then closes
the log file each time data is logged. If the log rate is less than 5 seconds, OneSix™
leaves the file open and closes the file when OneSix™ is terminated, the log rate is
set to zero, or the log rate is set to 5 or greater.
The log file can be viewed while OneSix™ is logging. The other program must not
write to the file, lock the file, set the file as read only, or set the file's sharing
parameters so that OneSix™ cannot log.
When processing data with another program, the best approach is to either rename
the file if the log rate is 5 or greater (OneSix™ will automatically create a new file on
the next log) or make a copy of the log file. When renaming, you may get an access
error. Just try again.
The Error log file is opened and then closed whenever OneSix™ writes an error
record.

TCP/IP Receivers
Overview of TCP/IP Receivers
OneSix can connect to TCP/IP receivers and receive and process sensors packets. As
of this writing, the Point Manager (operating in “Pass-Thru” mode) is the only
supported TCP/IP receiver. OneSix makes a TCP/IP connection to a receiver and
then waits for sensor packets. OneSix then processes the sensor packet as if it came
from a receiver (like PointView). OneSix can initiate the connection or it can receive
connections from a receiver. OneSix can maintain multiple connections
simultaneously (only limited by the resources of the host computer).
Setting up to use TCP/IP Receivers
The TCP/IP Receiver must be assigned a valid IP address and IP port number. If the
TCP/IP Receiver is going to initiate the connection to OneSix then the TCP/IP
Receiver will need to be set up with the IP address and port number of the computer
that is running OneSix. See the manual for the specific receiver you want to use for
information about setting the IP addresses.
To prepare OneSix to use a TCP/IP Receiver, make sure the Port type is “TCP/IP
Receiver”. If you are using OneSix for the first time, select “TCP/IP Receiver” from
the “Select Communication Port” option when it shows a window displaying “Cannot
find Receiver”. OneSix will then display the “All Current IP Addresses” window.
You can select this window from the Setup menu. Click the “Add New” button to
add a new IP connection. Click the “Test” button to test the selected IP Address.
Click the “Edit” button to change the properties of a connection. When you click the
OK button, OneSix will attempt to the list of specified IP addresses. You can view
the status of the connections by selection the Setup Menu and then select “View IP
Connection Status” to display the “IP Status” window.
48 x TCP/IP Receivers
OneSix Server Help
Notes
If OneSix initiates the connection then OneSix will continually try to establish the
connection when the connection is disrupted or never accepted. If the receiver
initiates the connection, OneSix relies on the receiver to re-establish the connection if
the connection is disrupted.
Each TCP/IP connection is assigned a “node number”. This “node number” gets
associated with a sensor’s data. The “nodaladdress” OPC tag item is updated with
the “node number”.
Information about the individual TCP/IP connection is made available through the
Server OPC parameters (the “Nodex” OPC tag item). See the Server OPC topic for
more information.
OneSix can wait for connections initiated by the receiver. OneSix will automatically
add the TCP/IP connection to its list. OneSix waits on port 1060 by default. You
can change this port number through the OneSix INI file. In the “IP Addresses”
section change the “IPWaitPort=” line.

Corrections
Why Use Corrections
Some devices, like a thermistor, need their data corrected in order to be meaningful.
A thermistor uses resistance to measure temperature. The relation between the
resistance and the temperature is non linear. A thermistor uses a set of correction
parameters to convert resistance to temperature. Other devices may need to correct
data values in a non linear way. OneSixOPC provides a way for the user to correct
the data from a sensor using a set of correction parameters or a lookup table.
Correction IDs
Tell OneSixOPC that you want a device to use a correction by specifying the
Correction ID in the OneSixOPC.INI file. Within the device section add a line
saying "CorrID=" and the number of the correction that you want OneSixOPC to use.
The Corrections are found in the Correction.INI file that you write.
Pre-defined Thermistor
The thermistor made by the vendor Thermometrics has the part number RL05035820-97-MS . This thermistor's parameters are predefined in OneSixOPC and given
the Correction ID 128. (In the device section of the OneSixOPC.INI file, write
"CorrID=128" to use this type.)
The parameters for the predefined thermistor are as follows:
NTC_DIVIDERES = 10000
NTC_NORMALRES = 10000
Fitting constants:
A = 3.3539264E-3
B = 2.5609446E-4
C = 1.9621987E-6
D = 4.6045930E-8
52 x Corrections
OneSix Server Help
How to use Corrections
Correction.INI file
After adding the Correction ID to the device section of the OneSixOPC.INI file, you
must set up the Correction used by that Correction ID. If you're using a correction
that is not predefined, you must write a Correction.INI file. This file should be
stored in the same directory as the OneSixOPC.INI file. Name your file
"Correction.INI" and include all the correction sections you like, from 1 to 127.
Include a CorrType, either 1 (for correction parameters) or 2 (for a lookup table).
Lookup Table
A lookup table is a CorrType of 2. If you do a lookup table, you must observe a
couple of rules. You must specify Elements, which is the number of values in the
list. The RawValues list and the CorrectedValues list must be of the same length.
The RawValues list must go from smallest to largest (numbers must be in increasing
order). When writing your lookup values, do not put a space after the comma. There
is a functional limit to the number of elements in the lists; roughly, 500 integer values
or 300 real values, for the RawValues and CorrectedValues taken individually.
Here is an example of a lookup correction section:
[Correction5]
CorrType=2
Elements=5
RawValues=400,450,500,550,600
CorrectedValues=1400,1450,1500,1550,1600
Thermistor NTC Parameters
You may choose to correct your sensor's data with a group of parameters. Use
CorrType 1. If you decide to use parameters, specify the parameters as in the
following example:
[Correction2]
CorrType=1
DivideRes=10000
NormalRes=10000
A=3.3539264E-3
B=2.5609446E-4
C=1.9621987E-6
D=4.6045930E-8
Predefined Corrections
The device type "Thermistor" will default to a correction ID of 128. To override this
default you can add a CorrID parameter to the device section of the OneSixOPC.INI
file, or you can set a new default for all thermistors in the Server section of the
OneSixOPC.INI file. To change the default CorrectionID for all thermistors add the
OneSix Server Help
Corrections x 53
parameter "DefaultThermistorCorrID=" to the Server section, and set it to whatever
CorrectionID you wish.
Predefined Corrections use the following equations. The first equation normalizes
the passed value, and the second produces the conversion to degrees Celsius.
Parameters:
NTC_DIVIDERES = 10000
NTC_NORMALRES = 10000
