The limiting values for detecting an underrange / overrange, a wire break 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 status named in this section occur or other internal error
statuses for the I/O module are present.
Note how long diagnostics are displayed!
A diagnosed error status is displayed at least 100 ms even if the detected error
status is no longer present in this period. If a higher-priority error status occurs in
this period, the higher-priority error status is displayed for 100 ms and the lower-
priority error status is lost.
