Explanation
• This register stores a category code indicating a type of the
error information which is stored in the common information
(SD5 to SD15) and the individual information (SD16 to
SD26).
b15 to b8 b7
Individual information category codes Common information category codes
• The common information category codes store the
following codes:
0: No error
1: Module No. (QCPU: Slot No./CPU No./base No., LCPU:
*1
Slot No./Block No.)
2: File name/drive name
3: Time (value set)
4: Program error location
5: Reason(s) for system switching (for the Redundant
CPU)
6: Reason(s) for tracking size excess error (for the
Redundant CPU)
7: Base No./power supply No. (This does not apply to the
Universal model QCPU and the LCPU with a serial
number (first five digits) of "10041" or earlier.)
8: Tracking transmission data classification (for the
Redundant CPU)
*1 For a multiple CPU system, the module No. or CPU No.
(CPU No.1: 1, CPU No.2: 2, CPU No.3: 3, CPU No.4: 4)
is stored according to an error. (For details, refer to
each error code.)
• The individual information category codes store the
following codes:
0: No error
1: (Empty)
2: File name/drive name
3: Time (value actually measured)
4: Program error location
5: Parameter number
6: Annunciator (F) No.
7: CHK instruction failure No. (Except for the Basic model
QCPU, Universal model QCPU, and LCPU.)
8: Reason(s) for system switching failure (for the
Redundant CPU)
9: Failure information (for the QnUDVCPU and LCPU)
12: File diagnostic information (for the Universal model
QCPU and the LCPU)
13: Parameter No./CPU No. (for the Universal model
QCPU)
