Evaluate value status
There is a bit value status for each digital input in the input address space.
Irrespective of the diagnostics enables, each value status (each QI bit) provides information on
the validity of the corresponding process value.
• Value status = 1: Process value okay, "good"
• Value status = 0: Process value not okay, "bad"
Basically, the value status is set to "good" if the digital value can be detected without error. The
value status is set to "bad" in the following cases:
• The digital value cannot be output due to an error.
• The digital channel is deactivated.
Note
The value status is not set to "bad" when there is a wire break on the channel and the wire break
test is disabled.
