L12 S11 Cannot find / copy block IW L12 S11 Function not defined FUNCTION FC42 : VOID VAR_INPUT MemAddr: INT; // Input to read END_VAR VAR_OUTPUT Val: INT; // value at MemAddr Location END_VAR Val := %IW(MemAddr) ; END_FUNCTION

So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
