I would like to establish a communication between 3, S7-300 315-2DP PLC, using the internal DP port.
PLC 1 has to read 20 words out of PLC 2 and 20 words out of PLC3.
And PLC 1 has to write 5 words to PLC 2 and 5 words to PLC3
I was thinking to make a master/slave communication (PLC1=master, PLC2 and PLC3=slave) and to use the functions PUT en GET (FB14/FB15)
I looked on the Siemens support site but could not found a useful example. Only some information on some manuals, but unfortunately, not sufficient for me….
Could somebody help me?
