32.11.2.2 Explanation of the JSUB and JSUBP Instructions
The JSUB and JSUBP instructions are time subtraction
instructions. When a JSUB instruction is executed, the time
variable in operand S2 will be subtracted from the time variable in
operand S1, and the result of the subtraction is stored in the time
variable in operand D1. The JSUB and JSUBP instructions always pass
power.

Hours are input in BCD.
|
VariableName.MIN
|
Integer Variable
|
Minutes are input in BCD.
|
VariableName.SEC
|
Integer Variable
|
Seconds are input in BCD.

In the JSUB instruction, you cannot run time subtract operations
on individual time variable elements (.HR .MIN .SEC).
The time variables and each element thereof are saved as BCD
data.
