15.12.4 Example for the "Analogue output" module
In the example, a device is connected to a mobile controller via the CAN interface . The device scales the
signals to 0 . .1 . The signals are then output via the mobile controller via a physical analogue switching
output .
Description of the modules used in the example:

Description
1
Basic function
The x values are filtered out (distance of ROI group 1) .
2
Fixed value
The fixed value "0" determines the start value for scaling .
3
Fixed value
The fixed value "10" determines the end value for scaling .
4
Scale
The x-values are set to the control range 0 . . .10 m . Example:

Analogue output
The x-values are scaled to 0 . .1 and output via the CAN interface .
To be able to process the analogue output values as current or voltage values via a physical
output, a programmable controller is required .
