D<=
Double-word less than or 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
less than or equal to B+1⋅B, the output is turned ON.

Example
When R010 is ON, the data of D0101⋅D0100 is compared with the constant data 0, and if the
data of D0101⋅D0100 is less than or equal to 0, R014 is turned ON.
If the data of D0101⋅D0100 is -1, R014 is turned ON.
D0101⋅D0100 -1 ≤ Constant 0 R014 is ON
If the data of D0101⋅D0100 is 10000, R014 is turned OFF.
D0101⋅D0100 10000 > Constant 0 R014 is OFF
Note
• This instruction deals with the data as double-word integer (-2147483648 to 2147483647).
