Error
information
category code
• Error information is stored in Error common information (SD5
to SD15) and Error individual information (SD16 to SD26).
• This register stores a category code indicating an error
information type.
• The common information category codes store the following
codes:
•0: No error
•1: Module No. (Slot No./CPU No./base No.)
*1*2
•2: File name/drive name
•3: Time (value set)
•4: Program error location
•5: Reason(s) for system switching (for Redundant CPU)
•6: Reason(s) for tracking size excess error (for
Redundant CPU)
•7: Base No./power supply No. (Except for the Universal
model QCPU and LCPU having the serial No. (first
five digits) of "10041" or earlier)
•8: Tracking transmission data classification (for
Redundant CPU)
*1 For a multiple CPU system, the module No. or CPU No. is
stored according to an error. (To determine whether a
storage value is a module No. or CPU No., refer to each
error code.)
CPU No. 1: 1, CPU No. 2: 2, CPU No. 3: 3, CPU No. 4: 4
*2 For the LCPU, only a slot No. is stored.
• 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
Redundant CPU)
•9: Failure information (for LCPU)
•12: File diagnostic information (for Universal model
QCPU and LCPU)
•13: Parameter No./CPU No. (for Universal model
QCPU)
