TableApp.19 Special register
• Error codes for errors found by diagnosis are stored as BIN data.
• Contents identical to latest fault history information.
• Year (last two digits) and month that SD0 data was updated is stored as
BCD 2-digit code.

to b7
Year (0 to 99) Month (1 to 12)
• The day and hour that SD0 was updated is stored as BCD 2-digit code.
b15 to b8 b7
Day (1 to 31) Hour (0 to 23)
• The minute and second that SD0 data was updated is stored as BCD 2-
digit code.
b15 to b8 b7
Minutes (0 to 59) Seconds (0 to 59)
Category codes which help indicate what type of information is being
stored in the common information areas (SD5 through SD15) and the
individual information areas (SD16 through SD26) are stored here.
The category code for judging the error information type is stored.

Individual information
category codes
• The common information category codes store the following codes:
0 : No error
1: Unit/module No./ CPU No./Base No.
2: File name/Drive name
3: Time (value set)
4: Program error location
5: System switching cause (for Q4ARCPU, Redundant CPU only)
6: Reason(s) for tracking capacity excess error (specific to Redundant
CPU)
7: Base No./Power supply No. (The first 5 digits of serial number
"10042" or higer are chosen for Universal model QCPU.)
8: Tracking transmission data classification (specific to Redundant CPU)
*: For a multiple CPU system that consists of the Basic model QCPU,
High Performance model QCPU, Process CPU, Universal model
QCPU the module number or CPU number is stored depending on the
error that occurred.
(Refer to the corresponding error code for which number has been
stored.)
CPU No. 1: 1, CPU No. 2: 2, CPU No. 3: 3, CPU No. 4: 4
• 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 number
7: CHK instruction failure No. (except for the Basic model QCPU and the
Universal model QCPU)
8: Reason(s) for system switching failure (specific to Redundant CPU)
12: File diagnostic information (specific to the Universal model QCPU)
13: Parameter No./CPU No. (specific to the Universal model QCPU)
