FUN 105 D<> Double-word not equal
Expression
Input −[ A+1⋅A D<> B+1⋅B ]− Output
Function
When the input is ON, the double-word data of A+1⋅A and B+1⋅B are compared, and if A+1⋅A is not
equal to B+1⋅B, the output is turned ON.
Execution condition
Input Operation Output
OFF No execution OFF

Example
When R010 is ON, the double-word data of D0101⋅D0100 is compared with the double-word
data of D0251⋅D0250, and if the data of D0101⋅D0100 is not equal to the data of
D0251⋅D0250, R014 is turned ON.
If the data of D0101⋅D0100 is 250000 and D0251⋅D0250 is 200000, R014 is turned ON.
D0101⋅D0100 250000 ≠D0251⋅D0250 250000 R014 is ON
If the data of D0101⋅D0100 is -100 and D0251⋅D0250 is -100, R014 is turned OFF.
D0101⋅D0100 -100 =D0251⋅D0250 -100 R014 is OFF
Note
• This instruction deals with the data as double-word integer (-2147483648 to 2147483647).
