Hi all,
We have discovered a really interesting phenomenon with our MicroLogix 1500 and our ENI module. It seems to be working fine, but out of the blue, the DF1 link between the ML1500 and the ENI module "disaapears". We have no way of remotely getting the link back online.. although we can connect to the remote ENI interface to see some info. The only way to restablish the link is to reset the breakers to both the ML1500 and the ENI module and reset them basically... then everything works.
ANybody know why this might be happening? Is there anything I can do automagically so that this doesn't keep happening?
We are considering using the CompactLogix series instead of the ML1500 because of the inability to do online edits, as well as the slow bus speed between the ENI and the ML1500.
Basically, if you can answer my two questions, or if we should just consider upgrading to the CompactLogix series of processor? There is a $2,000 price tag difference I think for our application.
Thanks a lot!
