LE_E

Outline

This function compares data with regard to "

≤ (smaller or equal)".

1. Format

*1.

Output variable

2. Set data

In explanation of functions, I/O variables inside ( ) are described.

Explanation of function and operation

1) This function compares the contents of devices specified in

…, and outputs the operation result

expressed as the bit type data to a device specified in

This function executes comparison [

≤

] & [

≤ ]

… & [

-1

≤ ].

a) This function outputs "TRUE" when all comparison results are "

(n-1)

≤ (n)".

b) This function outputs "FALSE" when any comparison result is "

(n-1)

> (n)".

2) The number of pins in

can be changed.

Cautions

When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different from
simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
