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.
