Operands:
S
1
: Time augend (occupies 3 consecutive devices) S
2
: Time addend (occupies 3 consecutive
devices) D: Addition result (occupies 3 consecutive devices)
Explanations:
1. TADD instruction adds the time value (Hour, Minute Second) S
1
with the time value (Hour,
Minute Second) S
2
and stores the result in D.
2. If operand S
1
, S
2
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.

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