RSTP Switches and com loops
Seems like a great idea, run your IP communication in a big loop to an RSTP switch, then the RSTP switch decides which way communicaitons goes, and if ever a com cable is compromised, you can't tell because the RSTP switch just sends the data through whatever path is available for that controller.
But how does the system operator know that there has been an issue? Are there any RSTP switches that will send an alarm via BACnet, or something we can integrate to, informing us that there has been a communication shift due to a broken com line?
