With the "Reset partner configuration" button you can delete the imported data again. The
partner-specific configuration data of the CP will then be deleted again.
Parameter groups after importing
The imported data is displayed in the "Subscriber X" directories. Apart from the "Parameter
status" parameter described below, the imported parameters cannot be configured any
further.
For the meaning of the parameters, see section Advanced options (Page 84). You will find
further information on the parameters in the STEP 7 information system.
Report partner status (connection to partner)
With individual partners, the reporting of the partner status can be enabled.
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.
