What causes fault code 60005 (Communication Timeout â€” DeviceNet)?

DeviceNet cable trunk or drop cable disconnected or damaged. Node power supply failed â€” DeviceNet requires 24VDC on the bus. Termination resistor missing from end of DeviceNet trunk â€” must have 121 ohm at each end. Node MAC address changed or conflicts with another node. DeviceNet scanner module needs parameter re-download or power cycle

How do I fix fault code 60005?

Check DeviceNet cable connections at the faulted node â€” push connectors fully in. Measure 24VDC at the faulted node DeviceNet port â€” should be between 11V and 25V. Verify 121 ohm termination resistors are installed at both physical ends of the trunk. Check node MAC address DIP switches â€” compare to scanner configuration. Power cycle the faulted node and watch for it to come back online in scanner diagnostics. If node does not return, try replacing with spare and setting same MAC address

Communication Timeout â€” DeviceNet

60005

DeviceNet node has stopped communicating. Scanner reports node offline and associated I/O data is invalid.
