Post subject:  S7-400 H System


This question has been asked a number of times already across these forums and no one seems to have an answer, so I will ask again in the hope that an expert out there may just have the answer.

How is PLC redundancy handled by the HMI as all attempts so far have resulted in an application that just sits there not talking to the current Master PLC. Basically, the HMI just hangs.

If anyone can shed any light on this can they please let me know as right now, if this problem cannot be solved we will have to drop the Beijer IX project and go with a tried and tested Siemens solution which just works!

Many Thanks

To get the Redundant system to work correctly I had to get beta test software from Beijers which was for the S7 ISO over TCP IP
