Set signal ranges

Notice

Signal ranges must be set before carrying out the cabling

Defects possible due to incorrectly set signal ranges.

  • Set the signal ranges before connecting the sensors and actuators.
  • Set the signal ranges in accordance with the specifications for the intended sensors and actuators.

The signal range can be individually set for each analog input and output. The parameters that define the signal range are located in the CoE directory:

Interface

CoE Index

Analog input „1“

F800:01

Analog input „2“

F800:02

Analog output „3“

F800:03

Analog output „4“

F800:04
