官方故障排除步驟
Parameters: %1 = PROFIsafe address %2 = Channel type, channel number %3 = System variable array index extension Definitions: The F module signals that an error occurred in the interface of the specified channel. This alarm is only triggered for ET200S F modules. The type of channel (input or output channel) is indicated by the abbreviations IN and OUT in %2. A specific alarm message can be programmed for each of the system variables on the HMI via parameter %3: - %3 = 1....64: Error in system variables $A_INSE[1...64] - %3 = 65...128: Error in system variables $A_OUTSE[1...64] - %3 = -1: Error in an input or output channel for which ther e is no SPL assignment Reaction: Mode group not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Trigger a STOP D/E (settable via MD $MN_SPL_STO P_MODE) on all axes with safety functionality.
