than or equal to B+1.B, the output is turned ON.
Execution Condition:
Input Operation Output
OFF No execution OFF
ON Execution A+1.A < B+1.B ON

Example:
When B010 is ON, the data of D0101xD100 is compared with the constant data 0, and if the data
of D0101xD0100 is less than or equal to 0, B014 is turned ON.
If the data of D0101xD0100 is -1, the comparison result is true. Consequently, B014 is turned
ON.
If the data of D0101.D0100 is 10000, B014 is turned OFF.
Note
This instruction interprets the data as double word integer (-2147483648 to 2147483648).
