alexgarlo Posted May 8 Report Share Posted May 8 Hi there, I have a problem with one connector. Two (NO)contacts working in parallel as an OR should activate the MB 1203 coil but this does not happen. I have these types of connections throughout the program and it has never given me problems. Additionally, there is no other conflict condition that disables MB1203 as seen in the image. It only lets me change the coil if I set it to ON through an online test. I have had the same problem on several PLCs. I don't know what I did but a plc magically fixed itself. Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted May 8 MVP 2023 Report Share Posted May 8 Is it subroutine with this net active? So is there a call to this subroutine in the main program? Link to comment Share on other sites More sharing options...
alexgarlo Posted May 8 Author Report Share Posted May 8 Yeah...my bad, it's a subroutine call in the main program😅I caught the error. This subroutine is only called with a condition that is not met, I didn't realize. Thanks for opening my eyes. Link to comment Share on other sites More sharing options...
