Hi there. i am new to this site and know little about plc's. I have a problem with one of our machines. Basically its a large washing maschine. it is overfilling with water. the level works on a pressure switch which is wired into a A/D converter (A1S64D) The switch has been changed and the problem is still there. The A/D converter was then changed for a spare in the stores. after powering the machine back up the converter and data link module light up for a second then the cpu run flashes and the error is lit constanly. The company does not have any information on this, but i managed to get some software downloaded from a plc site. Does anyone have any information they can give me about this. many thanks in advance tom
