Digital Output

The app “digital outputs” provides you with an overview of all digital outputs in your system. This is where you can name them and change the state of the outputs.

The app “digital outputs” is located under “all apps” – “digital outputs”.

You have two possibilities to change the state of a digital output. Either you can click on the power symbol on the left in the object panel or you can click on the button “switch” in the operator panel.


You can give a name to a digital output in the parameter panel and optionally allocate it to a room.

Save output if bus fault
If the output is active when the bus connection to the CPU fails (for example if the 24V power supply to the module fails), this option lets you guarantee that the active remains activated even in a fail state. If this option is not activated, then the output is reset after every bus connection failure.

In safety-critical controllers, it should be carefully examined whether this function should be activated, since this output is kept active if the system fails.

With the mode setting, you can change the behavior of the output once it is active. The following options exist:

  • Standard
    This ist the normal setting for a digital output. With this, the output stays active until the signal ends.

  • Minimum on duration
    With this mode, the output stays active for at least the specified time, even when it is deactivated before.

  • Pulse
    In this mode, the output will automatically be deactivated after the defined timeframe.

Reserve (hide in visualization)
If you have a digital output in your system that you do not use, then you can hide this digital output in the digital output app by activating the option “reserve (hide in visualization)” (located in the parameter panel). (To unhide, the digital output can be found in the hardware app).

Change mode
If you wish to change the mode, i.e. convert a digital output to a socket, then you can do this by changing the mode for the digital output in the parameter panel.


You can also use a digital output for a scene (in as far as it has been named). In the scene’s “if …” simply select the digital output to see the following possibilities:

Switch off
The digital output is switched off.

Switch on
The digital output is switched on.

switch on for
The digital output will be switched on for a defined amount of time.

The state of the digital output is toggled.
