1. Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2. Function with EN/ENO
The execution conditions and operation results will be as follows.
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
If the operation result is outside the data type range, convert the input value as appropriate before operation.
• When (s1) to (s28) are of REAL data type
• When (s1) to (s28) are of LREAL data type
Execution condition Operation result
EN ENO (d)
TRUE (executed) TRUE Operation result output value
FALSE (not executed) FALSE
*1
