efansa Posts: 3 Rating: (0)	I am configuring an S7-400FH system with two CP441-2 for redundant Modbus communications with DCS system ( the PLC being slave in the communication ). The communication appears to work fine, including the redundancy, but I am worried because the FB180 funcion shows some error codes in the CP_ERROR_NR and CP_ERROR_INFO parametersthat I have not been able to locate in any manual ( something like 3031 and 4B02 respectivaly for the FB180 of the main CPU, and 1110 and 0001 for the backup ). Is there any manual where I can find what these error codes mean? thanks in advance
