Please note: The entry of the value 0 (zero) is interpreted as a deactivated limit value.
Note
Evaluation of the value even when the option is disabled
If you enable one or both options and configure a value and then disable the option later, the
grayed out value is nevertheless evaluated.
To disable the two options, delete the previously configured values limit values from the input
boxes and then disable the relevant option.
Recommendation for quickly fluctuating analog values:
If the analog value fluctuates quickly, it may be useful to smooth the analog value first if limit
values are configured.

Options for specifying the communications partner

Telecontrol server enabled / Partners for inter-station communication
Here you specify who will be the communication partner of the data point.
If no CP was enabled as the partner for inter-station communication, the "Telecontrol server
enabled" option is selected automatically. In this case, the telecontrol server is the
communications partner of the data point.
If instead a CP of an S7 station should be the communications partner of the data point,
select the option "Partner for inter-station communication".
The telecontrol server and a CP in an S7 station cannot be selected as the partner at the
same time.
