Hi, I think you will never get the station to RUN mode because in a H-system both sides have to be equal! Regards |

Hi, Doesn't it matter that both sides of H-system aren't equal? Regard Saeid |

Hello Saeid, what matters is that you follow the rules mentioned in the 400H manual. Rules for the assembly of fault-tolerant stations The following rules have to be complied with for a fault-tolerant station, in addition to the rules that generally apply to the arrangement of modules in the S7-400: ● The CPUs have to be inserted in the same slots. ● Redundantly used external DP master interfaces or communication modules must be inserted in the same slots in each case. ● External DP master interfaces for redundant DP master systems must only be inserted in central units rather than in expansion devices. ● Redundantly used modules (e.g. CPU 41x-5H PN/DP, DP slave interface module IM 153-2) must be identical, i.e. they must have the same order number, the same product version or firmware version. So, yes you can have a single CP443-1 but you won't have redundant connection. Best regards, H-H |

Hello Myst, The H-station will run without problems. You can have different modules in each rack (rack 0&1) as long as you don't violate the rules mentioned in the 400H manual. Please, check my post in this thread. Regards, H-H |
