TIA Portal 15.1 Issues

Cannot remember on S7, but on some PLC's if the PLC is in stop mode, you can monitor but no outputs will be physically turned on check the PLC is not in stop mode (just a thought). Also, some PLC's require a supply to the card to energise the LED's as these may be after the opto isolator.

His 1200 has relay outputs, so it DEFINITELY needs power to the outputs before they will do anything.

Does the small LED on the PLC outputs go green when the output is activated? And have you used the correct output adresses (Q) that is linked to the outputs in thw hardware config?

Good Source for S7-1200

Now the PLC code issue is 'fixed' what about a safety device being tripped removing the power to the relay outputs

Did you remove the key from the ignition first? Please take a screenshot and post it. Thanks

Dont understand your comment

No power to the relay is typically a safety relay type issue

Don't mind my poor sense of humor, it was supposed to be self depricating as I always ask for pictures or screenshots no matter the issue.
