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 S7 stations with which the current station will use inter-station
communication. Connections for inter-station communication run via the telecontrol server.
The partner number is assigned by the system. It is required during data point configuration
to assign data points to their communications partners.
For inter-station communication, the partner is addressed with the parameters "Project",
"Station" and "Slot".
Here, enter the project number of the CP in the partner station. (Parameter group "Security >
CP identification" on the partner)
Here, enter the station number of the CP in the partner station. (Parameter group "Security >
CP identification" on the partner)
