24.2
Compare
NE(_E)
These functions output the data comparison result of input values.
*1 Supported by engineering tool version "1.035M" and later. In earlier versions, write in operator form. (

Descriptions, types, and data types
Processing details
■
Operation processing
• These functions perform a comparison operation of input values of (s) and output operation results from (d) in the BOOL
type.
• A data value of the INT, DINT, REAL, BOOL, WORD, DWORD, TIME, or STRING type can be input to (s).

Operation result
1.
Function without EN/ENO
The following table lists the operation results.
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.

d(NE(_E))
Output (TRUE: True value, FALSE: False value)
Output variable
BOOL
• NE(_E): These functions compare [(s1)
(s2)].
• When (s1)
(s2), these functions output TRUE.
• These functions output FALSE when (s1)=(s2).
