Logo changes the I1 mode after download

Hello everyone.

Thanks in advance for any help you guys can give me.

I am new to Logo! and found a strange behavior after download the diagram to the logo.

In the simulation function, the diagram works just fine, but after the download the LOGO changes the mode of the input 1.

In the diagram it is configured to work as a break, (momentary switch) and after the download, the logo changes to switch.

Any help is apreciated.

The diagram is attached.

Thank you guys.

Thank you Ixo65 for the help.

So, how do I monitor an Normally Closed input?

As you can see in the diagram, if the input stay opened for more the X seconds, Q1 closes the relay, activanting an alarm in the building.

Again, thanks for help.

What is actually connected to the input?

A window contact for an alarm system?

Which status has the input when it is in good condition? Open? Or closed?

 A magnetic sensor.

For a door actually, in an alarm system.

In good condition the contact must stay closed.

I tested again and it worked fine. The problem was in my conection to the sensor actually.

Thank you very much Ixo, for the help.
