Special Register List
• This register stores the error code of an error detected by
diagnostics.
• Contents identical to latest error history information.
• This register stores the year (last two digits) and the month when the
SD0 data is updated in 2-digit BCD.
B15 to B8 B7
Year (0 to 99) Month (1 to 12)
• This register stores the day and the hour when the SD0 data is
updated in 2-digit BCD.

Individual information
category codes
• The common information category codes store the following codes:
0 : No error
1 : Module No. (Slot No./CPU No./Base No.)
2 : File name/Drive name
3 : Time (value set)
4 : Program error location
5: Reason(s) for system switching (for the Q4AR and Redundant
CPU)
6: Reason(s) for tracking size excess error (for the Redundant CPU)
7: Base No./power supply No. (Universal model QCPU: This applies
to modules with a serial number (first five digits) of "10042" or
later.)
8: Tracking transmission data classification (for the Redundant
CPU)
1: For the multiple CPU system using the Basic model QCPU,
High Performance model QCPU, Process CPU, and Universal
model QCPU, the module No. or CPU No. is stored according
to an error.
(For details, refer to each error code.)
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 (F)number
7 : CHK instruction malfunction number (except for Basic model
QCPU and Universal model QCPU)
8 : Reason(s) for system switching failure (for the Redundant CPU)
12: File diagnostic information (for the Universal model QCPU)
13: Parameter No./CPU No. (for the Universal model QCPU)
