If the "Report partner status" function is enabled, the CP signals the status of the
communication to the remote partner.
– Bit 0 of "PLC tag for partner status" (data type WORD) is set to 1 if the partner can be
reached.
– Bit 1 is set to 1 if all the paths to the remote partner are OK (useful with redundant
paths).
– Bits 2-3 indicate the status of the send buffer (frame memory).
The following values are possible:
- 0: send buffer OK
- 1: send buffer threatening to overflow (more than 80 % full).
- 3: send buffer has overflowed (fill level 100 % reached).
As soon as the fill level drops below 50%, bits 2 and 3 are reset to 0.
Bits 4 to 15 of the PLC tags are not used and do not need to be evaluated in the program.
Partner for inter-station communication
Inter-station communication
In this table, you specify the communications partners of the CP for inter-station
communication. The communications partner is a CP in the partner S7 station.
Connections for inter-station communication run via the telecontrol server.
Note the special features when configuring the data points for inter-station communication in
the section Partner stations: Configuring the inter-station communication (Page 85).
The partner number is assigned by the system. It is required during data point configuration
to assign data points to their communications partners.
You specify the partner CP for inter-station communication with the parameters "Project",
"Station" and "Slot".
Here, enter the project number of the CP in the partner station.
You will find the parameter in the parameter group "Security > CP identification" on the
partner CP.
Here, enter the station number of the CP in the partner station.
You will find the parameter in the parameter group "Security > CP identification" on the
partner CP.
