When I change the inputs to be normally closed, my outputs then go High. Inputs work fine all the time. Outputs work only as normally closed. I checked the addresses, they are all correct. Please help. Regards,

Regards, hi Idir, It is not really clear what you are doing/programming. Maybe you can share your code or a screenshot of your configuration and the code. regards,
