27355 F_DP: %1 communication, connection %2 signals system error %3 (%4)
Parameter %1 = communication type
%2 = name or DP_DP_ID of the SPL connection
%3 = error detection
%4 = component
Explanation A system error was detected within the scope of the F_DP communication. Depending on the error, the
particular SPL connection or the complete F_DP communication is stopped.
The following displays are possible for communication type (%1):
- F_SENDDP
- F_RECVDP
- SPL
As connection (%2) the following displays are possible:
● Name or DP_DP_ID (ID) of the SPL connection (for communication type = F_SENDDP or F_RECVDP)
● "-" (for communication type = SPL)
One of the following error causes is possible (see fault ID %3):
● SF: Asynchronous fault state (StateFault)
● LS: Sign-of-life monitoring (LifeSign)
● TD: Discrepancies in the F-telegram data (TelegramDiscrepancy)
● OD: Deviations in the output data (OutputdataDiscrepancy)
● for communication type = F_SENDDP:
– $A_FSDP_ERR_REAC - <FSDP_ERR_REAC/>
● For communication type = F_RECVDP:
– $A_FRDP_SUBS -- <FRDP_SUBS/> $A_FRDP_ERR_REAC -- <FRDP_ERR_REAC/>
● SP: The SPL input/output data are not updated (SPL I/O-communication)
The specified error IDs, depending on the error profile, can also be displayed in a combination.
Further, the component involved (%4) is displayed in the alarm text:
- NCK
- PLC
- system variables (for error identifier = OD)
Response Alarm display
NC start disable in this channel
Mode group not ready
Channel not ready
NC stop for alarm
Interface signals are set
A STOP D/E is initiated (this can be set using MD10097 $MN_SAFE_SPL_STOP_MODE) on all axes with
safety functionality.
Stopped SPL connections - type F_RECVDP - output failsafe values (0) in the direction of the SPL as F-net
data.
Remedy Power-down/power-up the control (power on). If this fault occurs again, contact the service department.
Program con‐ Switch control system OFF and ON again.
