When the input is ON, the double-word data of B+1 × B is subtracted from A+1 × A , and the result is
stored in C+1 × C . The data range is -2147483648 to 2147483647.
If the result is greater than 2147483647, the upper limit value 2147483647 is stored in C+1 × C , and the
output is turned ON. If the result is smaller than -2147483648, the lower limit value
-2147483648 is stored in C+1 × C , and the output is turned ON.

Example
When R005 is ON, the double-word data of RW25×RW24 is subtracted from the double-word data
of D0101×D0100, and the result is stored in D0103×D0102.
If the data of D0101×D0100 is 1580000 and the data of RW25×RW24 is 80000, the result 1500000
is stored in D0103×D0102, and R010 is turned OFF. (No overflow/underflow)
