There is a fault on the 20-COMM-D Card.

Page 4-6 of PF70 Manual:

Port 1-5 Adapter 71-75
The communications card has a fault.
Check DPI device event queue and corresponding fault information for the device.

20-COMM-D Manual:

You will have to log onto the 20-COMM-D with the PF70 HIM, find out what the error is, and rectify it.

Hello again!

I have a quick question, so I'm just going to continue in this semi-related thread.

There is a Micrologix 1500 and PowerFlex400 connected vie DeviceNet. Is it possible to program parameters of PowerFlex via DeviceNet?
