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.
• NE(_E): These functions compare [(s1)(s2)].
• When (s1)(s2), these functions output TRUE.
• These functions output FALSE when (s1)=(s2).
• 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.
Operation result
No operation error occurred
An operation error occurred
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*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.
