Parameterize signal ranges
Note
An incorrect signal range can cause damage to devices. Parameterize the signal ranges
according to the specifications of connected devices.
The signal range can be individually parameterized 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
