Output
Function
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)
