Programming example

First, a Loxone Intercom is paired.

The block is automatically created when the Loxone Intercom is dragged from the periphery tree to the programming page:

The doorbell button input of the Intercom must be connected to the block's Ib input.

A separate doorbell can be connected to output Qb. Outputs Q1 - Q3 are used to control user-defined functions, such as door strikes and lighting. These can be named in the properties of the function block and are then available in the user interface to control the corresponding output.

A double-clicking on the block allows you to select Audio Player blocks. These will then play the doorbell sound when the doorbell is rung.
