-- F_SENDDP/F_RECVDP: System variable $A_FSDP/FRDP_ER-
ROR = TRUE
-- F_SENDDP/F_RECVDP: System variable $A_FSDP/FRDP_DIAG
<> 0
-- F_RECVDP: System variable $A_FRDP_ACK_REQ = TRUE
-- F_RECVDP: Output of the substitute values specified in the system
variable $A_FRDP_SUBS
-- For programmed error response $A_FSDP_/FRDP_ERR_REAC =
0, in addition an alarm and STOP D/E are initiated
Check the PROFIBUS communication and the communication partner.
Note
Only the F_DP communication is acknowledged for a user acknowledg-
ment via DB18.FRDP_ACK_REI. The alarm is still displayed and must
be separately acknowledged using NC--RESET.
Remove the error and issue a user acknowledgment via a channel_1
reset.
F_DP: %1 communication, connection %2 signals error %3
%1 = communication type
%2 = name or DP_DP_ID of the SPL connection
%3 = error detection
There is an F_DP communication error with the external communica-
tion partners and the programmed error response is
$A_FSDP_/FRDP_ERR_REAC = 2 (alarm, only display).
The following displays are possible for communication type (%1):
-- F_SENDDP
-- F_RECVDP
As connection (%2), the name or the DP_DP_ID (ID) of the F_DP
connection relationship 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.
-- TO: The parameterized communication timeout has been exceeded.
All of the specified error IDs, depending on the error profile, can also be
displayed in a combination.
