27350 F_DP: %1 communication, connection %2 signals error %3
Parameter %1 = communication type
%2 = name or DP_DP_ID of the communication relationship
%3 = error detection
Explanation There is an F_DP communication error with the external communication partners and the programmed error
response is $A_FSDP_/FRDP_ERR_REAC = 0 or 1.
The following displays are possible for communication type (%1).
- F_SENDDP
- F_RECVDP
As connection (%2), the name of the DP_DP_ID (ID) or the SPL connection is displayed.
One of the following error causes is possible (see fault ID %3):
● SN: An error was detected in the telegram sequence.
● CRC: A CRC error was detected.
