PROFIBUS: diagnostics of S7 connections with STEP 7
What diagnostics options are available for S7 connections in STEP 7?
For the topic of "Communication in Automation" we have created a sample application entitled "S7 Communication between S7-300 and S7-400 via PROFIBUS CPs with BSEND / BRECEIVE and multiple job references (R_IDs)". Based on a practical example we have worked out a solution in the form of a description and executable code. The answer to your question is included in one of the chapters. We have made this solution chapter available for you as an excerpt in the form of a PDF document ready for downloading:

If you wish to benefit from the advantages of the entire sample application, you can download this in the portal for Applications & Tools.
