  • Steady flashing: Ethernet link awaiting configuration or configuration in process.
  • 2 flashes: no MAC address.
  • 3 flashes: Ethernet cable not connected on the module or Hub side
  • 4 flashes: the IP address is duplicated by another IP address on the network. Module is set to its default IP address. Conflicting remote device flashing in the same way.
  • 5 flashes: the Ethernet channel is configured as a BOOTP client and is waiting for a BOOTP server response.
  • 6 flashes: Invalid IP address. Module is set to its default IP address.
  • 7 flashes: the version of the Ethernet firmware is incompatible with the PLC processor firmware version (in cases where there are updates and user downloads).
