Source device Word
D
：
Device in which the result is stored Word
Explanation:
1. The value of the hour, the value of the minute, and the value of the second in the real-time
clock specified by S
2
are added to the value of the hour, the value of the minute, and the value
of the second in the real-time clock specified by S
1
, and the sum is stored in the register
specified by D.
2. The operands S
1
, S
2
, and D each occupy three consecutive devices.
3. If the sum is larger than or equal to 24 hours, SM602 is ON, and the result gotten from the
subtraction of 24 hours from the sum is stored in D.
4. If the sum is 0 (0 hour 0 minute 0 second), SM600 is ON.
Example:
When M0 is ON, the instruction T+ is executed. The alue of the hour, the value of the minute, and
the value of the second in D10~D12 are added to the value of the hour, the value of the minute, and
the value of the second in D0~D2, and the sum is stored in D20~D22.

Additional remark:
1. If the value in S
1
or S
2
exceeds the range, the operation error occurs, the instruction is not
executed, SM0 is ON, and the error code in SR0 is 16#2003.
2. If S
1
+2, S
2
+2, or D+2 exceeds the device range, the operation error occurs, the instruction is
not executed, SM0 is ON, and the error code in SR0 is 16#2003.
3. If users declare the operand S
1
in ISPSoft, the data type will be ARRAY [3] of WORD/INT.
4. If users declare the operand S
2
in ISPSoft, the data type will be ARRAY [3] of WORD/IN.
