Hello, i Believe you would have found the answer by now. if not then try this: I am using PRO-H software (IEC 61131-3) with exact same processor. you just add you input address as %IW#.# eg. %IW6.0 where 6 is the card position and .0 is input number. also be careful that the card i am using, its full resolution is 4095 steps (12 bit). same data structure is used for H-Ladder i believe. hopefully its little bit helpful. Regards.
