I want to make a simple warning system of technical alarms. For this I use a dry contact module of HDL.
The system works correctly, when I'm inside it, but when I´m running in the background is not working. What can be wrong?
Attach the project to be better understood.
Note: To make the system work I had to use the "Security Dry Contact Read Status" option and also had to make ask the state of this variable at some time period, otherwise not give me the information about the state of the dry contact.
