Note:
With loaded EtherCAT Master firmware only the M12 channel 0 can
be used, channel 1 is deactivated. Beginning with the EtherCAT Master
firmware version 3 channel 1 can be reactivated if redundancy is
activated. For the Open Modbus/TCP firmware with V2.3.4.0 and higher
both M12 channels can be used.
