Instruction 52- Unsigned Less Than or Equal To
Expression:
Space Requirement: 1 line x 5 column Location Requirement: Middle, Right rail
Function:
When the input is ON, the data of A and the data of B are compared, and if A is less than or
equal to B, the output is turned ON.
Execution Condition:
Input Operation Output
OFF No execution OFF
ON Execution A < B ON
A > B OFF

Example:
When B0005 is ON, the data of D0125 is compared with the constant data 35000, and if the data
of D0125 is less than or equal to 35000, B020 is turned ON.
If the data of D0125 is 35000, the comparison result is true. Consequently, B020 is turned ON.
If the data of D0125 is 0, the comparison result is false. Consequently, B0020 is turned OFF.
Note
This instruction interprets the data as unsigned integer (0 to 65535).
