What does xxxx 0110 mean?

An invalid FSoE address was detected during communication. This means a device is either configured with an incorrect address or is attempting to communicate with an unassigned or out-of-range address. It prevents proper safety device identification and communication, rendering safety functions inoperable.

Complete Troubleshooting Guide

  1. 1

    Verify that each FSoE slave device has a unique and correctly configured FSoE address within the safety domain.

  2. 2

    Ensure the FSoE master configuration matches the addresses of all connected FSoE slaves.

  3. 3

    Recheck the address assignment process in the engineering software, especially after device replacements.

  4. 4

    Confirm there are no IP address conflicts if the FSoE addresses are linked to specific network configurations.
