1fn Posted May 31, 2014 Report Posted May 31, 2014 Not a smart one though but am stuck in a silly problem, i am unable to read inputs through opc from cpu 314c 2dp. There is no problem in reading I/Os other than built in. The built input lights up as it should when switch operates but no change in internal bit is observed. Is there is anything am missiing out or these I/Os need some sort of activation or like ?? Quote
