Precautions when Converting the Projects

• When converting projects of the FX3 Series using GX Works3, be careful because the program (instructions and devices)
may be changed.
• When converting projects, the number of steps may increase and writing to the FX5 CPU module may be impossible.
Check the number of steps after replacement.
• Characters used for the label name in GX Works2 may correspond to reserved words or illegal characters in GX Works3. In
that case, change the label name.
