Hello guys. I have a challenge with my S7 200 PLC system that I would love to get help with. I have a CPU 224, EM223, EM231, EM277, EM231 in that order. The first EM231 (AI4x12Bit) has analog addresses AIW0, AIW2, AIW4 and AIW6. I would want to imagine that the second EM231 (AI4x12Bit) has addresses AIW8, AIW10, AWI12 and AIW14 but when I connect signals to these addresses, I don't read any values. Could I be looking at wrong addresses? Or do I need to locate the second EM231 before the EM277 (Profibus Slave Module)? Thanks in advance. ------------------------------------------------------------------------------------------ |
