Transfer data from one s7 1200 to another via ethernet

Morritz Posts: 2 Rating: (0)	Hello, I first acknowledge am a beginner. I need to send data from one s7 1200 plc to another. I have come across the TSEND C and TRCV C instructions and tried going through several explanations to no avail. What are the parameters that should be put in the CONNECT part of the TSEND C? [All explanations show a datablock, but when I point to one, it gives some sort of error, mostly incompatible data type] I am using TIA V11, an unmanaged switch and two s7 1200 cpu 1214C. A documented tutorial on usage would be highly appreciated. Attachment TSEND.jpg (407 Downloads)

Morritz Posts: 2 Rating: (0)	Thanks alot. I had missed the connection part (pairing between PLCs). It now works but I have come across a new issue. When I update a value to be sent within the program, it updates the value in all paired PLCs but when I do the same via a HMI, it doesn't. Am I missing something? Thanks in advance.
