Hello, Hello, It's allowed to wire 2 1BL00 modules in paralel for redundant load connections, this module has no diagnostics. See SIMATIC S7-400 S7-400 Automation System Module Data for more details of both cards. Regards, Marcjan |
Problem solved? |

Hello, In the following FAQ you can find the whole list of modules (central/decentral) that support I/O redundancy for an H configuration: Redundant I/Os with S7-400H systems Best regards, Hamid Hosseini |

Thank you Hamid. That settled the issue if the entry is still valid (note that it is from 2004) 422-1BL00 does not support redundant DO, only 422-7BL00 does, as the entry stated.

You are welcome AMAZINGAHMED , It is not difficult to check if the list is valid now.In section 13.14.1 of the manual for the Fault-tolerant CPUs( V6 -->2013-10-22) ,you can find a similar list.You can check both or even a newer reralease of H CPU manuals.
Best regards, Hamid Hosseini |
