Outline

This function compares data with regard to "

≠ (unequal)".

1. Format

*1.

Output variable

2. Set data

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

Explanation of function and operation

This function compares the contents of devices specified in

and

, and outputs the operation result

expressed as the bit type data to a device specified in

This function executes comparison [

≠

a) This function outputs "TRUE" when in the case of "

≠

b) This function outputs "FALSE" when in the case of "

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.
