Re: [ECS] PLC Interface overflow? Paul Fitch Fri, 30 Jun 2000 19:44:27 -0400

I have recently noticed exactly the same sort of overflow error.  In an attempt
to find out what was being sent, I activated PLC Monitor.  Unfortunately, this
only monitor received commands, not transmitted ones.  I then attempted to query
the status of PLC-Interface-2H...but, it only tracks receiving NOT transmitting
status.

So, is there a method of tracking what commands are being sent by ECS?  I would
think that ECS has a central command transmit processor so the commands that are
being transmitted should be easy to identify and log....
