Dear friends,

Can anyone help me to understand, what is the reason that all inputs are energized but output is not energized? Screen shot is attached. RSLogix 5000

Do a cross reference for that output. Is there another instance of it in your program? Is this routing being scanned by the main routine. Basic questions, but that is the first thing to check.

Steve got it first ! The rung conditions arent true!
