Report partner status
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.
