Hello,

I am having some problems with DO module. As you can see in the attached screenshot, when the input I8.7 is ON (input of the DI/DO module 6ES7 374-2XH01-0AA0) the output Q5.0 turns ON after 3 seconds. But the light of the DO module Q5.0 doesn't light on. The same happens when I try to force some input of the DI module to 1, neither the software nor hardware input turns on. Could you helo me with this?

Thank you

Have you rechecked the hardware addresses in your HWConfig?

Regards

Daniel.

Hi,

Have you checked the status of Q5.0 in watch table? Is it ON in Watch table?

Use Cross Reference to make sure the Q5.0 is not used more than once in the logic as output. 

 Yes, I checked the hardware addresses. Find attached picture.

 Do you mean in this watch table? I see nothing in that.

It's a very simple program, so I only used this output once.
