1.2.13 SUBTRACT TIME Instruction (TMSUB)
„ Outline
The TMSUB instruction subtracts one time (hours/minutes/seconds) from another time. The
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 and Source are with the appropriate ranges, the operation will be
performed normally. After the operation is completed, the [Status] is turned OFF. If the con-
tents 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.
