I have a problem in terms of inputs and outputs, when I create a tag for a variable% MW1 and I run it . i had a BAD display for my tag. So my problem is the fact that I can not implement the correct configuration in vijeo citect of my API TSX MICRO knowing that I use a serial cable (RS485)for communication between the PLC and a PC and software PL7 pro as PLC. is there any system requirements for this kind of problems.
