using clipper pmac, when working it shown the below fault message.


The vital circuit was reset by the remote side. Close all connections to PMAC including PMACServer then replug.

what's the problem and how to solve this ?
This message appears when serious communication error occurs due to following reasons
1. Unplug or other wire breaks
Sol: Make sure that all wires are good and connections are tidy. Also, you can eliminate any switch or hub issue by replacing the extra hardware by a single crossover cable.
2. Pmac is non-responsive due to watchdog tripping or excessive servo load
Sol: Check the status of watchdog LED (red) when problem occurs. Normal mode is OFF. Also, try to turn off PLCs and run your test again. You can achieve it by simply setting I5=0

I hope it helps
