Offizielle Schritte zur Fehlerbehebung
Parameters: %1 = Cause of the error %2 = Parameter %3 = Number of the affected bus Definitions: The PROFIBUS/PROFINET was not generated in the SDB in accordance with the configuration specifications of the NC in use. Overview: Cause of the error, Par 1: - 01 = SDB contains slave/device withou t diagnostics slot, slave/device address - 02 = SDB contains too many slot entries, identifier - 03 = SDB contains no equidistance data, no function. - 04 = PNIO: SDB contains differe nt Tdp (also TDC) on a device - 05 = PNIO: SDB contains differe nt Tmapc (also CACF) on a device - 06 = PNIO: SDB contains different TI on a device - 07 = PNIO: SDB contains different TO on a device - 08 = PNIO: SDB contains device numbers that are too high (with values higher than 126) - 09 = SDB contents are transferred segmented (too many slots/frames) - 20 = SDB contains too many slaves/devices, quantity. - 21 = SDB missing or contains invalid data, error code. - 22 = SDB configuration data incorrect, slave/device address, error code - 23 = Reserved - 24 = Reserved - 25 = Reserved - 26 = Reserved - 27 = Reserved - 28 = Reserved - 29 = Reserved Reaction: Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: Check that the corresponding SDB - Contains a diagnostic slot for every slave/device, and - Contains only slave/device entr ies relevant to the application. In general, it is possible to incl ude a superset of slaves/device in th e SDB that are partially relevant for different end versions of the product. However, this overloads the NC memory and runtime capacity, and should therefore be avoided in general. If this alarm occurs, it is necessa ry to reduce the SDB to a minimum. If the code for the error cause is 03, check that equi distance is activated in the SDB (e.g. using STEP 7 HW config). If the alarm continues to occur, please send the error text to the control system manufacturer. Program Continuation: Switch control OFF - ON.
