Powerflex 70 Comm issues

I have a Powerflex 70 that periodically returns an Error 85 - Port 5 DPI Loss. I have looked through the AB Knowledgebase and they mainly talk about connections. Specifically, the HIM connection. I have removed the HIM and it appeared as though the problem was solved. I recently started seeing the fault again and I am planning on swapping out the drive to see if the problem goes away. Any other ideas?

Well Port 5 is the comm card that you have installed. What comm card are you using? If the comm card is the issue, it can be replaced without replacing the whole drive.

Is this the same PF70 VFD you refer to in your post about DH+?
