Processing details
■Operation processing
These functions output the absolute value of a value input to the input variable IN from the output variable OUT1, and output
the sign determination of the input value from the output variable OUT2.

Operation result
No operation error
Operation error
• Function block with EN/ENO
The execution conditions and operation results will be as follows.
Execution condition
EN
TRUE (operation execution)
FALSE (operation stop)
*1 If the value FALSE is output from ENO, the output data from this function block will be undefined. Create a program so that the
undefined value will not be used in operations.
Operation error
Error code Description

3402H Input 1 to 16 are subnormal numbers or NaN (not a number).
Processing
