Customer Support, Profibus Fault on Case Packing machine

David Tye

Requested to try and diagnose an intermittent Profibus fault on an ETT case packing machine. With only 6 nodes on the Profibus network the machine would stop randomly with a profibus error while in motion. Using some trap code inserted into the PLC OB’s and a screwdriver, the fault was tracked down to a damaged Profibus Connector making some nodes drop off the network due to the vibration. This was replaced and the machine was put back into service.
