BACnet MS/TP

Check the following to troubleshoot your WSHP Open:
Verify that the BAS and controller are both set to speak the BACnet MS/TP protocol on the Comm Selector
1
DIP switches DS3 - DS6.
Verify that the BAS and the controller are both set for the same baud rate:
2
•
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.
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 controller has a unique MAC address on the MS/TP bus. The controller's MS/TP MAC address
4
is set by its rotary address switches.
Verify that the BAS is reading or writing to the proper BACnet objects in the controller. Refer to Appendix A for
5
the points list for the controller.
BAS must be reading or writing to the proper addresses on the controller. Refer to Appendix A (page 28) for
6
the points list of the controller.
Verify that the BAS is sending his requests to the proper MS/TP MAC address of our controller.
7
Present the BAS company with a copy of the controller's BACnet PICS so that they know which BACnet
8
commands are supported. Refer to Appendix B for the BACnet PICS. In certain situations, it may be necessary
to adjust the MS/TP Protocol timing settings through the BACview
It may be necessary to adjust the following two MS/TP Protocol timing settings through the BAC
device:
Max Masters - defines the highest MS/TP Master MAC address on the MS/TP network.
For example, if there are 3 master nodes on an MS/TP network, and their MAC addresses are 1, 8, and 16, then
Max Masters would be set to 16 (since this is the highest MS/TP MAC address on the network).
This property optimizes MS/TP network communications by preventing token passes and "poll for master"
requests to non-existent Master nodes.
