I have S7 400H PN port and two CP1623 card. But i am not able to select Enable max. redundancy(4 connection). It is always disabled. I can do same setting from WinCC side but when I again open PLC side connection it gives message"old connection is no longer valide" and gain goes to 2 connections. What is the reason? ------------------------------------------------------------------------------------------ |

HI, so it works from a WinCC perspective, but it is a Hardware topic. Seems that you Hardware config in your PLC is wrong. B.R. |
