You have the following configuration options:
•
Configuration 1: without value status

Evaluating the value status
An additional byte is occupied in the input address space if you enable the value status for
the analog output module. Bits 0 to 3 in this byte are assigned to a channel and return
information about the validity of the analog values or the channel status.
Bit = 1: No error on channel.
Bit = 0: Error on channel.
