Operands:

S1: Time augend (occupies 3 consecutive devices)

S2: Time addend (occupies 3 consecutive

devices) D: Addition result (occupies 3 consecutive devices)

Explanations:

1.TADD instruction adds the time value (Hour, Minute Second) S1 with the time value (Hour, Minute Second) S2 and stores the result in D.

2.If operand S1, S2 exceed the available range, operation error occurs and M1067 = ON, M1068 = ON. D1067 stores the error code 0E1A (HEX).

3.If the addition result is larger than 24 hours, the carry flag M1022 will be ON and the value in D will be the result of “sum minuses 24 hours”.

4.If the sum equals 0 (00:00:00), Zero flag M1020 will be ON.

Program Example:

When X0 = ON, TADD instruction executes and the time value in D0~D2 is added with the time value in D10~D12. The addition result is stored in D20~D22.

	X0		TADD	D0	D10	D20
	D0	08(Hour)	D10	06(Hour)	D20	14(Hour)
	D1	10(Min)	D11	40(Min)	D21	50(Min)
	D2	20(Sec)	D12	06(Sec)	D22	26(Sec)
08:10:20			06:40:06		14:50:26

If the addition result is greater than 24 hours, the Carry flag M1022 = ON.
