  • Steady Green: Indicates that the module is communicating with the CPU over the backplane.
ERR
Red
  • Off: Indicates one of the following states:
    • Power is not being supplied to the module.
    • The module is running a self test.
    • The module is operating normally.
  • Steady Red: Indicates one of the following states:
    • The module is not operational.
    • The module has detected at least one event.
  • Flashing Red: The module is in one of the following states:
    • The module is not configured, or is being configured.
    • The module is not receiving an X-Bus variable that should come periodically or cyclically from the PLC.

  • Steady Amber: The module is configured and operational.
  • Two flashes: The module does not have valid IP parameters.
  • Three flashes: The Ethernet link is not connected.
  • Four flashes: The module has detected a duplicate IP address.
  • Five flashes: The module is configured as a BOOTP client and is waiting for a BOOTP server response.
  • Six flashes: The module is using its default IP configuration.
  • Seven flashes: The module has detected a configuration error.
Note: If more than one of the above conditions is detected, the module will display the condition identified by the sequence of fewest flashes.
