I'm new user on this site. I would like to ask You for help. I have Simatic S5 (S5-95U)and I have problem whit input card. Sometimes all outputs go to digital "1" and line(winder)works alone. Interest me if anyone know how repair input card, which IC is broken. I know that input cart is broken because I have a lot of PLC's S5 and I changed good card then PLC works normally. With kind regards.
