Integrated Digital Input

haris_usama Posts: 81 Rating: (2)	Hi! I am having trouble using the integrated digital input on the 314C-2DP cpu V3.3.7. The input is wired, address is set from 124..126. I can see the green LED go on when the input is high, but my simatic manager or tia portal scans no change on this address. The first module, I126 works fine. The led goes on, and so does the logic change but the second integrated module (16DI/16DO) is behaving this way. Anyone with similar problems? Regards, Haris

Other possible cause the inputs are in use by technological functions (counters) Regards, Marcjan Attachment s7300_cpu_314c_pinout.pdf (421 Downloads)
