(2) Floating-point operation processing ("Floating point arithmetic processing")
( Section 8.1.2(2)) Note10.3Note3
The time required for processing instructions that uses floating-point data can be shortened. To shorten the
processing time, deselect the "Perform internal arithmetic operations in double precision" item in the PLC system
tab of the PLC parameter dialog box.
For the operation processing time of the instruction that uses floating point data, refer to the following.
