CNU summer student Rob Ryan will be looking into this. Mike Johnson has an EPICS way of doing this, Vardan can do this in AFECS. Current thinking is that the AFECS mechanism is the way to go.

From Mark Stevens:

I recall that you are perhaps having a student look at the software/internet monitoring of the Libert UPS in the counting room. Are you aware that the RDC has the capability of communicating too, with optional equipment? And are you aware that the RDC may have a built-in monitoring system that self-protects and sends out alarms for overcurrent, and that it is factory-programmed for single-phase 20 Amp circuits? Will we need to reprogram this system to avoid erroneous faults, because we are installing larger circuits? I read about all of this in the Liebert RDC manual, while I was looking for information about circuit breakers. Perhaps your student could check this out.
