Input variables constitute the link to sensors, to output variables from other function modules, or to
other sources.
Selecting the icon will display all the input variables of the function.
Selecting an input variable will display all available sources to choose from.
• User
• Inputs
• Outputs
• Functions
• Fixed values
• System values
• DL bus
• CAN bus analogue
• CAN bus digital
After selecting the source, you can make the additional selection within the required source.
Important: For every input variable, it is important to note the input signal type:
Analogue (numeric value) or Digital (OFF/ON).
The descriptions of the function modules state the signal type for every input variable. Digital input
signals (ON/OFF) can be applied as standard or inverse.
Every function module has the Enable input variable, which represents the fundamental activation of
the entire function. It permits simple blocking or enabling of the entire module by means of a digital
signal (ON/OFF).
Certain input variables are always required for the functioning of the module and cannot be set to
unused. They appear with a dark background on the screen and are highlighted in the function
description. Other input variables can be used optionally.
