DearImport-User-1, Have a look into thisthread.TheHMI & Redundant-System .pdfwill help you to configure redundant CPU with Flexible. Revert Back for any clarification. |

DearImport-User-1, To the best i know, you can use Wincc Flex with the redundant S7300 CPU's.Now important is configuring the same on S7 end and Flexend. I had done a similar thingwith S7400 Redundant CPU's. You need to write an FC where in you detectwhichCPU is master(Ref DB5DW8 - Status Word) from the status word. Now based upon which CPU is master SET an bit and reset another bit and usethem in WinCC Flex. Now for Flex you need to make 3 connections 1st - CPUA 2nd - CPUB 3rd - Dummy Make all the tags on the Dummy connection initially. Then for the CPU A when you set a Bit Just write an action to change the connections of Dummy to CPU A and similarlyscript on anotherbit setting forCPU B. This will provide the change connection in flex. Using this bits you can also show Which CPU is master. We have the change connection as a standard function available in the Flex. Hope this info is fruitful in configuring the System. Thanks... |
