The menu item "blocking function" appears only for the settings for the switch function
channel if selected "Use blocking functions: Yes".
The output channel can be blocked by a block telegram. What happens during the
blocking, for bus voltage return and after the blocking is set here. The manual
operation is then not possible for an active block.
The function can be used for example for a light, which is turned on when pressing a
"panic button" (=trigger for blocking function) and cannot be turned off any longer.
6.2.5.4.Button input (switch functions)
Depending on the model, there are no inputs, two or four inputs.
The inputs can be used as actuator button or bus button. If a temperature sensor (eg.
T-NTC) is connected, the input is configured as a push button with function
„temperature sensor (NTC)“.
