8.3.2 Reading if limit exceeded or undershot
If a limit event occurs during operation, it has the fol-
lowing effects on measuring operation:

Threshold value display indicates an unusual
state.

If an output for the corresponding limit channel
is programmed, it is switched.
If the message Limit appears, the color of the status
display changes to white and the numbers of the
limit channels are listed with their channel numbers
in
red if limits have been exceeded or undershot.
Inactive limits are indicated with " _ ".
