*The monitoring must be activated separately or deactivated
The limiting values for detecting an underrange / overrange, a wire break or an
overload 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 of the error statuses named in this section occur. If there are any of the
diagnostics for range violation, overload or wire break, the bit for general error is
always set.
