官方故障排除步骤
Parameters: %1 = Error %2 = SDB source %3 = Bus number %4 = SDB number Definitions: Error in SDB for configuring PROFIBUS/PROFINET. Causes of the error: - 01 = SDB does not exist in source. - 02 = SDB from source is too large. - 03 = SDB from source cannot be activated. - 04 = Source is empty. - 05 = Source is not present. SDB source: - 99 = Passive file system: _N_SDB_DIR - 100 = CF card: /siemens/sinumerik/sdb/... - 101 = CF card: /addon/sinumerik/sdb/... - 102 = CF card: /oem/sinumerik/sdb/... - 103 = CF card: /user/sinumerik/sdb/... Reaction: PROFIBUS/PROFINET is inacti ve or working with the default SDB. Reaction: Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. Remedy: - Check the setting of MD 11240 $MN_PROFIBUS_SDB_NUMBER. - If source = 100: Check directory _N_S DB_DIR in the passive file system. - If source = 103-106: Check directories on CF card Program Continuation: Switch control OFF - ON.
