Operation processing
• These functions output the absolute value of the INT, DINT, or REAL type data input to (s) in the same data type as (s) from
(d).
• These functions are expressed as follows when the input value is "A" and the output operation result is "B".
• A value input to (s) is the INT, DINT, or REAL type data value.
• When -32768 is input while the data type of (s) is INT, -32768 is output from (d).
• When -2147483648 is input while the data type of (s) is DINT, -2147483648 is output from (d). (An operation error does not
occur. "ABS_E" outputs "TRUE" from output variable ENO.)

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.
