Partner stations: Configuring the inter-station communication
Options for specifying the communications partner
Telecontrol server activated / Enable partner for inter-station communication
If no partner was enabled for inter-station communication, the "Telecontrol server activated"
option is selected automatically. In this case, the telecontrol server is the only
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 "Activate 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.
Partner number for inter-station communication:
Specify the partner CP for inter-station communication for this data point by selecting the
partner number from the drop-down list.
The partners you specified in the table of the "Partner stations" > "Partner for inter-station
communication" can be selected. The access ID of the relevant partner is shown in brackets.
Index of the corresponding data point on the communications partner.
● The data pair of the sending and receiving CP must have an identical data point index. A
receiving data point of CP 2 corresponds to a sending data point of CP 1 with the same
data point index.
● For the opposite communications direction, a second pair of data points must be created:
A sending data point of CP 2 corresponds to the receiving data point of CP 1. Once
again, both have an identical data point index.
