官方故障排除步骤
Parameters: %1 = PROFIsafe address %2 = Incorrect F parameter Definitions: An error was detected during the evaluation of the F parameters. %2 = CRC1: CRC specified by F parameters faulty. %2 = F_WD_Timeout: The monitoring time parameterized in Step 7 is too small for the PROFIsafe cycle time defined by the MD $MN_PROFISAFE_IPO_TIME_RATIO. %2 = CRC2_Len: CRC message length faulty. %2 = F_Data_Len: the telegram length defi ned for the specified module is incorrect. Reaction: Mode group not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: %2 = CRC1: PLC overall reset, reload the S7 F configuration. %2 = F_WD_Timeout: reparameterize the PROFIsafe cycle time or F monitoring time. %2 = CRC2_Len: PLC overall reset, reload the S7 F configuration. %2 = F_Data_Len: PLC overall reset, reload the S7 F configuration. Program Continuation: Switch control OFF - ON.
