Commissioning The Controller For Lonworks Communication; Troubleshooting Lonworks - Carrier WSHP Open v3 Integration Manual

Communications wiring
Connect the LonWorks network to the LonWorks Option Card's 2-pin Net port.

NOTE The 2-pin Net port provides TP/FT-10 channel compatibility. The TP/FT-10 or "Free Topology" network
type is polarity insensitive. Use 24 to 16 AWG twisted pair wire.
Turn on the WSHP Open's power.

Commissioning the controller for LonWorks communication

Before a device can communicate on a LonWorks network, it must be commissioned. Commissioning allows the
system integrator to associate the device hardware with the LonWorks system's network layout diagram. This is
done using the device's unique Neuron ID.
A network management tool such as Echelon's LonMaker is used to commission each device, as well as, to assign
addressing. Specific instructions regarding the commissioning of LonWorks devices should be obtained from
documentation supplied with the LonWorks Network Management Tool.
When a new device is first commissioned onto the LonWorks network, the system integrator must upload the
device's External Interface File (XIF) information. LonWorks uses the XIF to determine the points (network
variables) that are available from a device. The WSHP Open has a set of predefined network variables. These
variables can be bound or accessed by the Network Management Tool.
The Browse feature of the Network Management Tool allows you to read real-time values from the WSHP Open.
The Network Management Tool allows you to test integration prior to binding the controller's network variables to
other LonWorks nodes.

Troubleshooting LonWorks

Check the following to troubleshoot your WSHP Open:
Verify that the BAS and controller are both set to speak the LonWorks protocol by theComm Selector DIP
1
switches DS3 - DS6.
The BAS and the controller are both set for the same baud rate:
2
38.4k for LonWorks
○
Baud rate DIP switches DS2 and DS1
○
Obtain a Modstat of the controller. Scroll to the bottom of the page to Network Communications to view
○
the active protocol and baud rate.
BAS must be reading or writing to the proper point addresses on the controller.
3
Verify that the Comm Option Port is enabled on the controller. The Comm Option Port setting must be set via
4
SW3 (switch DS7). It should be in the ON position to enable LonWorks communication.
Verify that controller has been properly commissioned onto the LonWorks network. See Commissioning the
5
controller for LonWorks communication (page 20).
