Hi everyone !
I´ve just begun to develop a ladder program for a SLC 5/03 PLC and I´m facing the folowing problem :
The application I´m developing is indeed a revision of the actual running code, which has some bugs to be fixed, but there´s a portion of it which I don´t need to rewrite since it´s error free. So I decided to copy this code portion and test it alone, but it doesn´t work, i.e, the ouputs are not set or reset according to the code, despite rung continuity. I don´t understand why this happens since the parameters of every instruction used by the code portion are digital inputs and digital outputs.
I know the info given above may sound a bit confused but any help you guys can provide will be deeply appreciated and, if some of you think it´s necessary, I´ll post the code portion here.
Thanks in advance !!
