Function
When the input is ON, the data of A and the data of B are added, and the result is stored in C.
If the result is greater than 32767, the upper limit value 32767 is stored in C, and the output is
turned ON. If the result is smaller than -32768, the lower limit value -32768 is stored in C, and the
output is turned ON.

Example
When R005 is ON, the data of D0100 and the constant data 1000 is added, and the result is
stored in D0110.
If the data of D0100 is 12345, the result 13345 is stored in D0110, and R010 is turned OFF.
D0100 12345
Constant 1000
+ D0110 13345 R010 is OFF
If the data of D0100 is 32700, the result exceeds the limit value, therefore 32767 is stored in
D0110, and R010 is turned ON.
