Soft redundancy using cp343-1 lean

Dear Ismu,

Could you please advise how did you make the soft redundancy using cp343-1 lean .

I have the same hardware configuration : cpu315-2dp +cp343-1 and another cpu315-2d+cp343-1 and wich are connected to IM155 (ET200MP) .

I need some manual showing how to do the programming and if you can send me your program between two cpu s7-300 doing the redundancy .

Also if anynone can help me from the technical support .

Thanks in advance,

Could you please advise how did you make the soft redundancy using cp343-1 lean .

1- The CP343-1 lean is used only for communication with HMI/SCADA. It can't be used to establish a redundant link.

2- The software redundancy isn't possible with IM155 (ET200MP) or in other words, the IM155(ET200MP) doesn't support redundant connection (i.e. both CPUs can't access the same IO rack).

Please, check Which modules can you use when implementing software redundancy?

3- Here's a link for software redundancy manual.

4- If you have the software redundancy CD (necessary to have the redundancy blocks), you will find some software examples.

5- You might need this FAQ collection when you start debugging your software.
