Guys, I have a Premium CPU (TSX957) with a SCY21601 Modbus Card and I need to talk to a Valve drive over modbus. I can set up the comms parameters (9600,8,1 etc) on the card but cant find out how to define my data (I want to read (function 3) 2 words (2) starting from adress 1234). Is there a function block that I am missing that handles this? I am using Unity pro V5.
Thanks in advance.
