Operands:
S
1
: Time augend S
2
: Time addend D : Addition result
Operand S
1
, S
2
, D occupies 3 continuous addresses
Description:
1. S
1
+
S
2
=
D . The time data in the registers specified by S
1
is added to the time data in the
registers specified by S
2
and the result is stored in the registers specified by D .
2. If the time data in S
1
, S
2
exceeds the allowable range, it will result in “operation error”. At this
time, the instruction will not be executed and M1067=ON, M1068=ON, and error code 0E1A
(HEX) will be written to D1067.
3. If the addition result is a value greater than 24 hours, the Carry flag M1022=ON. The value of
the result shown in D is the time remaining above 24 hours.
4. If the addition result is equal to 0 (zero, 0 hour, 0 minute, 0 second), the Zero flag M1020= ON.
Program Example:
When X0= ON, the instruction is executed. Add the time data specified by D0~D2 and D10~D12 and
store the result in the register specified by D20~D22.
