2.14 SPEND TIME Instruction (SPEND)
[Outline]
The SPEND instruction subtracts one time (year/month/day/hours/minutes/seconds) from another time
data and calculates the elapsed time. Source is subtracted from the Dest and the result is stored in the
Dest. The formats of Source and Dest are as follows.
Source Format
Register Offset Data Contents Data Range (BCD) I/O
0 Year (BCD) 0000～0099 IN
1 Month/Day (BCD) Upper byte (month) : 1 to 12
Lower byte (day) : 1 to 31 IN
2 Hours/minutes (BCD) Upper byte (hours) : 0 to 23
Lower byte (minutes) : 0 to 59 IN
3 Seconds (BCD) 0000～0059 IN
Dest Format
Register Offset Data Contents Data Range (BCD) I/O
0 Year (BCD) 0000～0099 IN/OUT
1 Month/Day (BCD) Upper byte (month) : 1 to 12
Lower byte (day) : 1 to 31 IN/OUT
2 Hours/minutes (BCD) Upper byte (hours) : 0 to 23
Lower byte (minutes) : 0 to 59 IN/OUT
3 Seconds (BCD) 0000～0059 IN/OUT

Total number of seconds This is the number of records which is
obtained by converting Year/Month/Day/
Hour/Minutes/Seconds, which is the results
of operations, to seconds. (Double-length
integer)
IN/OUT
If the contents of the Dest, Source and the operation result are with the appropriate ranges, the
operation will be performed normally. After the operation is completed, [Status] is turned OFF. If the
contents of the Dest and Source are outside the data ranges, the operation is not performed. In this case,
9999H is stored in the column "second" of the Dest, and the [Status] is turned ON.
