Lonworks - Carrier WSHP Open v3 Integration Manual

Troubleshooting
Verify that the BAS is configured to speak 2-wire EIA-485 to the controller. The BAS may have to configure
1
jumper or DIP switches on their end.
Verify that the BAS and the controller have the same communication settings (8 data bits, No Parity, and 1
2
stop bit).
Verify proper connection wiring between the BAS and the controller.
3
Verify that the rotary address switches are set for the controller's unique slave address.
4
BAS must be reading or writing to the proper point addresses on the controller.
5
BAS is sending requests to the proper slave address of the controller.
6
NOTE Refer to Appendix D (page 35) for the Protocol Implementation Conformance Statement.

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.
Verify that 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 through the BACview device. Click and hold the FN key and the . key at
○
the same time. 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.
1
Verify that the Comm Option Port is enabled on the controller. The Comm Option Port setting must be set via
2
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. Commissioning is done
3
with a network management tool such as LonMaker and allows the system integrator to associate the
controller with the LonWorks system's network layout diagram. This is done using the controller's unique
Neuron ID. The Network Management Tool is also used to upload the controller's .XIF file to determine the
network variables that reside inside of the controller.
Use the Browse feature of the Network Management Tool to verify that you can communicate and get real-
4
time values from the controller before connecting the BAS.
Once you have confirmed communications with the controller using the Network Management Tool, connect
5
the BAS.
Verify that the BAS is connected properly to the LON-OC's 2-wire TP/FT-10 Net port. The LON-OC's TP/FT-10
6
port is polarity insensitive. The BAS may have to configure jumper or DIP switches on their end to support
TP/FT-10.
