Table 48: Behavior in the Event of an I/O Module Error Dependent on the Configuration

Configuration
Wire break/
short circuit
monitoring
OFF
OFF
ON
ON
The limiting values for detecting an underrange / overrange, a wire break, short
circuit or a limiting value underrange / overrange and the output process values
are specified in the process image tables (see section "Process Image").
A general error signals a diagnosed error status. A general error is displayed if
one or more of the error statuses named in this section occur or other internal
error statuses for the I/O module are present. If there are any of the diagnostics
for range violation, short circuit or wire break, the bit for general error is always
set.
