Explanation of function and operation
1) This function obtains the absolute value of word [signed]/double word [signed]/float (single precision) data
stored in a device specified in
the data type of data stored in devices specified in a device specified in
This function is expressed as follows when the input value is "A" and the output operation result is "B".
B= A
2) When the data type stored in a device specified in
this function outputs "-32768" to a device specified in
function is "32,767".)
When the data type stored in a device specified in
2147483648", this function outputs "-2147483648" to a device specified in
value handled by this function is "2147483647".)
Cautions
Use the function having "_E" in its name to connect a bus.
