Hello,
I have an existing application that has a Powerflex 700 with a 20-COMM-E adapter controlled by a Micrologix 1100 via Ethernet. The setup works great sometimes but not other times. The micrologix is sending run, enable and speed commands to the drive using MSG commands. For seemingly no reason the MSG stops commanding the drive and stars generating timeout errors. After 15 minutes to an hour of sitting, it starts communicating again. According to the 20-COMM-E status lights, the Ethernet link is good but the drive is not receiving commands.
The Ethernet link is a direct connection from the micrologix 1100 to the 20-COMM-E.
I've tried a different 20-COMM-E module with the same results.
I've tried a new PLC with the same results.
Any ideas or solutions would be greatly appreciated.
Also, what would be the best method for setting up communications between the micrologix and the powerflex? I've been reading that Ethernet is not a good solution. I prefer get the Ethernet connection working but I'm open to converting to a different communication setup.
Thanks!
