The following table describes the temporarily variables of
the diagnostic interrupt OB 82:
Variable Data type Description
OB82_EV_Class byte Event class and identifier:
• B#16#39: incoming event
OB82_FLT_ID byte Fault identification code (B#16#42)
OB82_PRIORITY byte Priority class (priority of OB execution)
OB82_OB_Numbr byte OB No. (82)
OB82_RESERVED_1 byte Reserved
OB82_IO_FLAG byte Input module: B#16#54
OB82_MDL_ADDR word Logical base address of module with fault.
OB82_MDL_DEFECT bool not relevant (0)
OB82_INT_FAULT bool not relevant (0)
OB82_EXT_FAULT bool not relevant (0)
OB82_PNT_INFO bool not relevant (0)
OB82_EXT_VOLTAGE bool not relevant (0)
OB82_FLD_CONNCTR bool not relevant (0)
OB82_NO_CONFIG bool not relevant (0)
OB82_CONFIG_ERR bool No configuration: Shows that the checksum of
the actual configuration is wrong.
OB82_MDL_TYPE byte not relevant (0)
OB82_SUB_MDL_ERR bool User module is wrong or missing
OB82_COMM_FAULT bool Communication fault
OB82_MDL_STOP bool not relevant (0)
OB82_WTCH_DOG_FLT bool not relevant (0)
OB82_INT_PS_FLT bool not relevant (0)
OB82_PRIM_BATT_FLT bool not relevant (0)
OB82_BCKUP_BATT_FLT bool not relevant (0)
OB82_RESERVED_2 bool not relevant (0)
OB82_RACK_FLT bool not relevant (0)
OB82_PROC_FLT bool not relevant (0)
OB82_EPROM_FLT bool not relevant (0)
OB82_RAM_FLT bool not relevant (0)
OB82_ADU_FLT bool No compensation: Shows that the checksum of
the actual compensation data is wrong.
OB82_FUSE_FLT bool not relevant (0)
OB82_HW_INTR_FLT bool not relevant (0)
OB82_RESERVED_3 bool not relevant (0)
OB82_DATE_TIME date and time Date and time the OB started.
If you do not program OB82, the CPU changes to stop mode when a diagnostic inter -
rupt is triggered.

The following address information are meant as offsets in each input or output win -
dow. E.g. if the input range definition starts at PEB 300 (German Mnemonics) an ac -
cess to offset 1 means L PEx 301 where x can be B or W. All further absolute access
within the xx7 programming relate to the above definition.
