Hello, The new CP 443-1 (6GK7 443-1EX30-0XE0) can be used as compatible replacement for the CP 443-1 (EX20), irrespective of the firmware version of the employed CPU, provided the software blocks AG_SSEND (FC53), AG_SRECV (FC63), TSEND (FB63), TRCV (FB64), TCON (FB65), TDISCON (FB66) are used. |

I'm not sure this is obligatory. Only CPUs, sync-modules and memory cards must be the same part number and version. You are free to mix any other thing. You can use one 443-1EX20 in a rack and 443-1EX30 in the other rack. You can even use different power supplies (but both CPUs must be in the same slot). Best regards, H-H Hello, It's stated in theSIMATICFault-tolerant SystemsS7-400H manualthat both racks mustbe identical. Please have a look on the extracted picture from this manual. Hope this helps. |

Hello my friend, Maybe you miss the partThis applies in particular to the slots. You may also miss the fact that you can install some one sided modules like FMs and CPs in H system (check appendix D in the same manual). This means both racks may have different hardware but the downloaded HW config. must be identical. Maybe I didn't express it clearly.So, i'll tell you my personal experience. In one of my projects I had H configuration with EX11 in both racks. Sadly, we lost one of the EX11 CPs. We installed the EX20 as a direct replacement to the faulty EX11. We had EX11 in Rack 0 and EX20 in rack 1 and it worked fine. The same case we have here forbaker.ajmal.
Best regards, H-H |
