Network Topology

Each L ON W ORKS communication module is equipped with an FTT-10A transceiver for network communications. This transceiver allows for (1) free topology network wiring schemes using twisted pair (unshielded) cable and (2) polarity insensitive connections at each node. These features greatly simplify installation and reduce potential network commissioning issues. Additional nodes may be added with little regard to the existing cable routing.

Free Topology Networks

A L ON W ORKS “free topology network” means that devices (nodes) can be connected to the network in a variety of geometric configurations. For example, devices can be daisy-chained from one device to the next, connected with stub cables branching off from a main cable, connected using a tree or star topology, or any of these configurations can be mixed on the same network (see Figure 4). Free topology segments require termination for proper transmission performance. Only one termination is required. It may be placed anywhere along the segment. Refer to the Echelon L ON W ORKS FTT-10A

Transceiver User’s Guide for details.

Free topology networks may take on the following topologies:

• Bus

• Ring

• Star

• Mixed - Any combination of Bus, Ring, and Star

Note: Limitations to wire lengths apply and must be observed.

Termination

A network segment is any part of the free topology network in which each conductor is electrically continuous. Each of the four diagrams is an illustration of a network segment. Some applications may require two or more segments; see the “Free Topology Restrictions” section on the next page of this manual. If necessary, segments can be joined with FTT-10A-to-FTT-10A physical layer repeaters

(see Figure 5). Refer to the Echelon L ON W ORKS FTT-10A Transceiver User’s Guide for details.

Free Topology Restrictions

Although free topology wiring is very flexible, there are restrictions. A summary follows below.

Refer to the Echelon FTT-10A User’s Guide for details. The maximum number of nodes per segment is 64.

1.

The maximum total bus length depends on the wire size (see Qualified Cables section for details).

2.

One termination is required in each segment. It may be located anywhere along the segment.

Wire Size Maximum Node-to-Node Length Maximum Cable Length

24 AWG 820 ft (250 m) 1476 ft (450 m)

22 AWG

16 AWG

1312 ft (400 m)

1640 ft (500 m)

1640 ft (500 m)

1640 ft (500 m)

The longest cable path between any possible pair of nodes on a segment must not exceed the maximum node-to-node distance. If two or more paths exist between a pair of nodes (e.g., a loop topology), the longest path should be considered. Note that in a bus topology, the longest nodeto-node distance is equal to the total cable length.

Note: The total length of all cable in a segment must not exceed the maximum total cable length.

Doubly Terminated Networks

You can extend the maximum total cable length without using a repeater by using a doubly terminated network topology (see Figure 6). The trade-offs are (1) this network topology must be rigorously followed during the installation and subsequent retrofits and (2) two terminations must be installed at the ends of the bus for proper transmission performance. Refer to Echelon L ON W ORKS FTT-10A

Transceiver User’s Guide for details.

Note: Limitations to wire lengths apply and must be observed.

Figure 6. Doubly Terminated Network Topology

Termination Termination

Doubly Terminated Topology Restrictions

The restrictions on doubly terminated bus topology are as follows:

1.

The maximum number of nodes per segment is 64.

2.

The maximum total bus length depends on the wire size (see the “Qualified Cables” section in this manual for details).

Wire Size Maximum Cable Length

24 AWG

22 AWG

16 AWG

2952 ft (900 m)

4590 ft (1400 m)

8855 ft (2700 m)

3.

The maximum stub length is 9.8 ft (3 m).

A stub is a piece of cable that is wired between the node and the bus.

4.

Two terminations are required in each segment. One must be located at each end of the bus.

IM 927-3

IM 927-3

Note: If the bus is wired directly to the node, there is no stub, and thus the stub length is zero. If you are wiring to a field terminal strip on a unit, you should account for any factory wiring between the terminal strip and the MicroTech III unit controller. This wiring is considered part of the stub.

Physical Network

Qualified Cables

Echelon has qualified three twisted-pair network communications cables that are available from a large number of different sources. Refer to the Echelon L ON W ORKS FTT-10A Free Topology

Transceiver Users Guide for cable specification details. Some local codes or applications may require the use of plenum-rated cable. The following cables meet this specification:

1.

TIA568A Category 5 cable (24AWG/0.51mm)

2.

NEMA Level IV cable (22AWG/0.65mm)

3.

Generic 16AWG (1.3mm) (similar to Belden 85102)

!

CAUTION

Do not install the cable in the same conduit with power wiring. The temperature of the cable must not exceed 131 ºF (55 ºC), which can result in personal injury or equipment damage if not avoided.

Note: Ideally, you should connect two unit controllers with one continuous piece of cable in order to reduce the risk of communications errors. If you must splice the cable, use crimp-type butt connectors (good) or solder (best). Do not use wire nuts.

Network Cable Termination

L ON W ORKS network segments require termination for proper data transmission performance. The type and number of terminations depend on network topology. Refer to the Echelon L ON W ORKS

FTT-10A Transceiver User’s Guide for details.

Addressing and Establishing Communication

L

ON

W

ORKS

Network Addressing

Every Neuron Chip has a unique 48-bit Neuron ID or physical address. This address is generally used only at initial installation or for diagnostic purposes. For normal network operation, a device address is used.

Device addresses are defined at the time of network configuration. All device addresses have three parts. The first part is the Domain ID, designating the domain. Devices must be in the same domain in order to communicate with each other. The second part is the Subnet ID that specifies a collection of up to 127 devices that are on a single channel or a set of channels connected by repeaters. There may be up to 255 subnets in a domain. The third part is the Node ID that identifies an individual device within the subnet.

A group is a logical collection of devices within a domain. Groups are assembled with regard for their physical location in the domain. There may be up to 256 groups in a domain. A group address is the address that identifies all devices of the group. There may be any number of devices in a group when unacknowledged messaging is used. Groups are limited to 64 devices if acknowledged messaging is used.

A broadcast address identifies all devices within a subnet or domain.

Commissioning the Network

Pressing the service pin generates a service-pin message, which contains the Neuron ID and the program code identification of the node. A service-pin message is a network message that is generated by a node and broadcast on the network. It can be used to commission the L ON W ORKS network.

A network configuration tool maps device Neuron IDs to the domain/subnet/node logical addressing scheme when it creates the network image, the logical network addresses and connection information for all devices (nodes) on the network.

External Interface File (XIF) and NXE Files

L ON M ARK guidelines specify exact documentation rules so that proprietary configuration tools are not required to commission and configure L ON W ORKS devices. The L ON W ORKS Communication

Module is self-documenting so that any L ON W ORKS network management tool can obtain all the information needed over the network to connect it into the system and to configure and manage it.

An external interface file (a specially formatted PC text file with the extension .XIF) is required, along with L ON W ORKS network management tool, so that you can design and configure the device prior to installation.

The NXE file contains the application image that is downloaded into the L ON W ORKS Communication

Module. The L ON W ORKS Communication Module uses a separate NXE file specific to the WSHP-

SCC functional profile.

The XIF and NXE files are available at www.

DaikinApplied.com

or www.lonmark.org. Refer to MicroTech III WSHP Unit Controller Protocol Information, ED 15103 for additional details.

14 IM 927-3

Resource Files

Resource files contain definitions of functional profiles, network variables types, configuration property types, and enumerations. Resource files are used during the commissioning process and are

required for displaying user-specific variables that are not included in the standard device profile.

These files must be downloaded to the BAS front end workstation or other commissioning device.

They are available at www.

DaikinApplied.com

or www.lonmark.org. Refer to ED 15103 for additional details.

The Network “Wink” Command

A wink command is initiated by the BAS or through the L ON W ORKS commissioning software. The

“wink” identification function allows verification of an individual unit controller network address without having to physically open the unit’s access panels. The compressor shuts off during this period and the Minimum Compressor Off Timer must expire before the compressor is allowed to run again. The Wink command can be used during all operating and non-operating modes (ex. Alarms) except for Brownout Mode.

Upon receiving a wink command from a network management node, the Unit Controller exhibits the following identification sequence (all occur simultaneously):

•

Room Sensor LED flashes (on 0.5 sec, off 0.5 sec) for 15 seconds.

•

Fan: The fan turns off for 5 seconds, turns on for 5 seconds, then off again for 5 seconds.

•

Compressor: The compressor turns off for a minimum of 15 seconds.

Configuring the Unit Controller

The L ON W ORKS communication module is L ON M ARK 3.4 certified and is configured in accordance with the L ON M ARK Space Comfort Control (SCC) functional profile. The unit controller, along with the

L ON W ORKS communication module, is ready to operate with the default parameter values in the unit controller. Refer to the ED protocol document for descriptions of the available L ON W ORKS variables.

IM 927-3 15
