Issue
Upgraded a UNC-510 to Niagara version 522 and when trying to run the station, the following error appears: "Cannot load BACnet MSTP Driver"
Environment
- Niagara version 522
- UNC-510
Cause
The upgrade process does NOT change the drivers.properties file.
Resolution
The error indicates the line: driver.mstp=tridium.nre.vxworks.mstp.VxWorksMstpDriver is missing from the driver.properties file.
Copy the drivers.properties file from a UNC-520 running version 522 or higher or manually add this line into the drivers.properties file.
Note that the UNC-510-2 has a maximum baud rate of 19.2 k for a BACnet MS/TP network.
