Analogue Input (AI)

The “OUT” contains the actual position signal from the Val Controls Device. Values 0.00 to
100.00%
Configuration
If you want to change the sensor input just change the CHANNEL register in the AI Block.

If the IHP24 status is “Error”, FF-Fieldbus status on the AI channel goes to “Bad”
