BACnet MSTP
Check the following to troubleshoot your RTU-MP:
1
Verify that the BAS and controller are both set to speak the BACnet MS/TP protocol on the Comm
Selector DIP switches DS3 - DS6 .
2
Verify that the BAS and the controller are both set for the same baud rate:
○
Comm Selector DIP switches DS2 and DS1
○
By getting a Modstat of the controller through the BACview. Click and hold the FN key and then click
the . key at the same time. Scroll to the bottom of the page to the section entitled Network
Communications to view the active protocol and baud rate.
3
Verify that the BAS is configured to speak 2-wire EIA-485 to the controller. The BAS may have to
configure jumper or DIP switches on their end.
4
Verify that the BAS and the controller have the same communication settings (8 data bits, No Parity, and
1 stop bit).
5
Verify proper connection wiring between the BAS and the controller.
6
Verify that the controller has a unique MAC address on the MS/TP bus. The controller’s MS/TP MAC
address is set by its rotary address switches.
7
Verify that the BAS is reading or writing to the proper BACnet objects in the controller. Refer to Appendix
A for the points list for the controller.
8
Verify that the BAS is sending his requests to the proper MS/TP MAC address of our controller.
9
Present the BAS company with a copy of the controller’s BACnet PICS so that they know which BACnet
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 BACview6.
It may be necessary to adjust the following two MS/TP Protocol timing settings through the
BACview:
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.
