I can reconstruct your message with my code, even got response from PLC. But in a response packet I'm always getting two Headers and Footers with some data that cannot understand what they represent.
In your example what actually represent length C4 ?

Still can't get it to work. What kind is that binary request without message details ?
I have datatable with just one part of project column LONG size, and want to read just one value in request (one cell). -
Hi, Saragani. Did you manage to look into source code for more information about operation 75 ?

I can't get it to work. "Part of the project" column is 4 bytes long. I'm using Flash address as seen in Visilogic as start adress for request, is that correct ?

I'm not. I'm using binary mesage format (as described in your PDF manual) within my own c++ code.
