The error sometimes goes away when i pull out the plc cable and reconnect them (sometimes after 10 times...), and then the OP works normal. After a reset, the same error :-( I programm the op with protool lite, the cable is an original siemens. When i pull the cable, the op gives "plc not connected" so i think the cable is ok ? I also tried on a S100 cpu 102 plc -> the same error. The plc setting are correct (or not..) Dit i do something wrong ? is there another setting, i did forget ? I'm a beginner with OP's... Thanks in advance, Ronny
