Hello everyone,

We have two CPU models namely IM151-8 PN/DP and 314C-2 PN/DP. In the IM151-8 CPU we program two blocks of  GET(FB14) and PUT(FB15) respectively for communication of read/write data transfer between them. In the program the GET block is working fine(Without errors), but the PUT block is returning error bit as 1 and error code as 1. We saw this error description: "Communications problems",in siemens help document.

But how can there be communication problems when the NetPro shows OK(Active) status in both the local and partner connections. And moreover, the Get block is able to run successfully without errors and the immediate put block not able to..

Any reasons for this ? Can some expert help us find out where we are going wrong ? Some immediate help is needed.

Thanks

Akshay

Hello,

We had solve this issue by establishing new connection in NetPro. 

According to this new connection ID, the GET/PUT block is networked with correct addresses.

Now this solution works fine.

Thank you for your response!!!!
