Offizielle Schritte zur Fehlerbehebung
Parameters: %1 = Type of communication %2 = Name or DP_DP_ID of the SPL connection %3 = Error code %4 = Component Definitions: A system error has been detected during F_DP comm unication. Depending on the error, the relevant PROFIsafe driver or the entire F_DP communication will be stopped. The communication type is displayed in %1 %1 = F_SENDDP %1 = F_RECVDP %1 = SPL %2 = Name or DP_DP_ID (identifier) of the SPL connection ( with %1 = F_SENDDP or F_RECVDP) %2 = - (with %1 = SPL) The detected error cause is displayed in %3: %3 = SF: asynchronous error state (StateFault) %3 = LS: sign-of-life monitoring (LifeSign) %3 = TD: discrepancies in the F telegram data (TelegramDiscrepancy) %3 = OD: discrepancies in the output data (OutputdateDiscrepancy) - with %1 = F_SENDDP: $A_FSDP_ERR_REAC - DB18.DBW190,200,210) - with %1 = F_RECVDP: $A_FRDP_SUBS - DB18.DBW220,232,244) $A_FRDP_ERR_REAC - DB18.DBW222,234,246) %3 = SP: no update of the SPL input/output data (SPL I/O-communication) The mentioned values for %3 can be displa yed also combined depending on the fault profile. The affected component is displayed in %4: %4 = NCK %4 = PLC %4 = system variable (with %3 = OD) Reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Stopped SPL connections of type F_RECVDP out put failsafe values (0) as F user data. Remedy: Power OFF/ON of the control. If the error occurs again, inform the service department. Program Continuation: Switch control OFF - ON.
