Function Explanation

NE is used for a not-equal comparison of two variables and constants. Out is TRUE if
In1ǂIn2.
Otherwise, Out is FALSE.

The input parameters In1 and In2 are allowed to be the variables of different data types in this
instruction when the data types of input variables are not BOOL, TIME, DATE, TOD and STRING.
When the data type of one input variable is one of BOOL, TIME, DATE, TOD and STRING, input
parameters
In1 and In2 are both required to be of the data type. For example, if the data type of In1
is TIME, the data type of In2 must be TIME. Otherwise, an error will occur in the compiling of the
software.

Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software
if any input variable is omitted. But the output variable is allowed to omit.

The data type of output variables must be BOOL. Otherwise, an error will occur during the
compiling of the software.
