Hi, To decode the hex code printed in the CPU Diagnostic buffer one should relate these codes with respective error OB and its Temp Variables. Ex. Message in CPU Diagnostic Buffer is - 16# 3942 1952 D054 00E0 0D15 0000 then decoding of this Hex code is as below - 16#39 - OB82_EV_CLASS 16#42 - OB82_FLT_ID 16#19 - OB82_PRIORITY 16#52 - OB82_OB_NUMBR 16#D0 - OB82_RESERVED_1 16#54 - OB82_IO_FLAG 16#00E0 - OB82_MDL_ADDR 16#0D - Total 8 Bits - OB82_MDL_DEFECT, OB82_INT_FAULT, OB82_EXT_FAULT, OB82_PNT_INFO, OB82_EXT_VOLTAGE, OB82_FLD_CONNCTR, OB82_NO_CONFIG and OB82_CONFIG_ERR 16#15 - OB82_MDL_TYPE - Bit 0 to Bit 7 16# 0000 - Total 16 Bits - OB82_SUB_MDL_ERR, OB82_COMM_FAULT, OB82_MDL_STOP, OB82_WTCH_DOG_FLT, OB82_INT_PS_FLT, OB82_PRIM_BATT_FLT,, OB82_BCKUP_BATT_FLT, OB82_RESERVED_2, OB82_RACK_FLT, OB82_PROC_FLT, OB82_EPROM_FLT, OB82_RAM_FLT, OB82_ADU_FLT, OB82_FUSE_FLT, OB82_HW_INTR_FLT and OB82_RESERVED_3 Vijay Kulkarni |
