I have not build a system yet but are in the design stage.

Want to use multiple Logo's in my house all connected to LAN.

What happens if you use a network input from another Logo and this one is not accessible as for example Logo defect/off or LAN down .. would this trigger an error ?

This way we can create a dummy circuit just to detect if there is a problem.
