1.2.14 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.
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.
