Beckhoff Communication Error Capture

Problem

If one of the cards in a daisy-chained Beckhoff system has problem, the problem can cascade upward and cause whole system to hang up. In order to identify the problem node, we need to log which card causes the problem. The problem card normally shows up as not in operating mode (OP) with lot of communication error.

Steps to identify the renegade card

  1. Access System Manager by clicking on  near the clock area.
