5.7.6 NE_E
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.
