DWORD between two AC500 PLCs
I have two ABB AC500 PLC's (A&B) in my Application and i need to send double word From PLC A to PLC B. I tried with just a word and it works but since i am grabbing data in PLC A which exceeds the word limit so i need to put a double word but while i send the data, it gives an erroneous value. The Plc is talking Modbus TCP/IP. How can i send straight double words between two ABB plc's. Are there any calculations needed? How do i get this thing working?
I would appreciate it!
