3.3.5 Digital inputs and outputs
3.3.5.1 Function
The function of the digital inputs and outputs listed here can be parameterised. The signals at the
digital inputs trigger the parameterised function (e.g. “Release holding brake”). The signals at the
digital outputs map the parameterised signal (e.g. “Objective reached”).
Parameters and diagnostic messages
ID Px. Parameters Description
Defines the switching logic of the digital inputs and outputs.
Here 0 means: NPN logic (ground is switched) and 1 means: PNP
logic (a potential is switched).
Specifies the switching logic of the digital inputs and outputs.
This means:
–
0: NPN logic (earth is switched)
– 1: PNP logic (a potential is switched)
