Operation Start Time
A515 to
A517
The time that operation started as a result of changing
the operating mode to RUN or MONITOR mode is stored
here in BCD.
A515.00 to A515.07: Seconds (00 to 59)
A515.08 to A515.15: Minutes (00 to 59)
A516.00 to A516.07: Hour (00 to 23)
A516.08 to A516.15: Day of month (01 to 31)
A517.00 to A517.07: Month (01 to 12)
A517.08 to A517.15: Year (00 to 99)
Note
The previous start time is stored after turning ON
the power supply until operation is started.
Read/write
Operation End Time
A518 to
A520
The time that operation stopped as a result of changing
the operating mode to PROGRAM mode is stored here
in BCD.
A518.00 to A518.07: Seconds (00 to 59)
A518.08 to A518.15: Minutes (01 to 59)
A519.00 to A519.07: Hour (00 to 23)
A519.08 to A519.15: Day of month (01 to 31)
A520.00 to A520.07: Month (01 to 12)
A520.08 to A520.15: Year (00 to 99)
Note
If an error occurs in operation, the time of the
error will be stored. If the operating mode is then
changed to PROGRAM mode, the time that PRO-
GRAM mode was entered will be stored.
