I've been running into some communication issues with BACnet network (I/A UNC / Tridium )
Dealing with I/A UNC with intermittent blips that show all controller objects as being "down" when looking at them at Work Place Pro, but then all returns to normal after a few seconds. At WPT, everything runs without any problems, and there is no communication timeout (NaN) which would indicate a real loss of communication from the UNC through WPT.
Spoke to a colleague who advised that there is a limit to the number of switches that can be placed on a network "backbone"(?) and that this limit may be exceeded causing these issues.
Anyone run into anything like this? Is my collegues suspicions correct?
