*The pointer value is in word A300, which is in the read-only area (words A256 to A511).
Although each of them contains a different record, the structure of each re-
cord is the same: the first word contains the error code; the second word, the
error contents, and the third, fourth, and fifth words, the time, day, and date.
The error code will be either one generated by the system or by
FAL(006)/FALS(007); the time and date will be the time and date from the
Calendar/Clock Area, words G001 to G004. This structure is shown below.
Word Bit Content
First 00 to 15 Error code
Second 00 to 15 Error contents
Third 00 to 07 Seconds
08 to 15 Minutes
Fourth 00 to 07 Hours
08 to 15 Day of month
Fifth 00 to 07 Month
08 to 15 Year
Operation When the first error code is generated, the relevant data will be placed in the
error record after the one indicated by the Log Record Pointer (initially this
will be record 1) and the Pointer will be incremented. Any other error codes
generated thereafter will be placed in consecutive records until the last one is
used.
If there are words allocated for n errors and n errors occur, the next error will
be written into the last position, n, the contents of previous error will be
moved to record n–1, and so on until the contents of record 1 is moved off
the end and lost, i.e., the area functions like a shift register that moves data
in units of error records (5 words). The Record Pointer will remain set to n
(binary).
The Error Log Area can be reset by turning ON bit A00014 (Error Log Reset
Bit). When this is done, the Record Pointer will be reset to 0000, the Error
Log Area will be cleared, and any further error codes will be recorded from
the beginning of the Error Log Area.
3-6-16 CPU Bus Unit Initializing Flags
Bits A30200 through A30215 turn ON while the corresponding CPU Bus Units
(Units #0 through #15, respectively) are initializing.
3-6-17 Wait Flags
Bit A30600 is ON when the CPU Rack Power Supply Unit start input termi-
nals are OFF.
