FCU - BACnet Network - Problem with the BACnet Network number in Niagara communication

Issue

On the Niagara station, there are a few BACnet MS/TP networks configured; each has iSMA-B-FCU devices. While adding another device using a discover function and trying to move the discovered device to a specific station, iSMA-B-FCU devices previously added to the station change their numbers.

Possible solution

The solution is to set unique addresses to the FCU devices, according to the BACnet standard. If setting unique addresses is not possible, then it is required to switch off the Routing Enable function in the BACnet communication driver in Niagara.
