Hi Dmitry

Thanks for the answer, but I can´t make it work yet.

It seems that it is completely blind to the Dry Contact.
Please check the attached where I have a sample project where I followed you recommendation and also put a successfull relay control for the same module.

Detail operation:

When I HDL-search, it founds a 4-Ch relay (200/5). It works. But no Dry contact.
Nevertheless I insert manually the dry contact as you suggest, but no response. Maybe I am doing something wrong.

I appreciate if you can check it.

Best Regards,
