2. OVERVIEW OF PROGRAM CONVERSION USING FX-20P-E
2.4
Editing Programs
After converting F programs to FX programs and writing them into FX3 series programmable con-
trollers, check and modify them. The GX Works2 programming software is recommended to edit
programs. It is compatible with the FX3 series, and device replacement and other functions can be
performed easily. For information on how to operate the programming software, refer to the man-
ual.
The converted programs are equivalent to FX
and edit them according to the FX3 series system that you have built based on the conversion
rules described in Chapter 3 and subsequent chapters.
(1) Changing the device number
The device converted using the program conversion function is within the device range of FX
and FX
.

(Refer to Chapter 3.2 Device Conversion.)
Some special devices are converted to temporary devices due to differences in functions.
(Refer to Chapter 3.2.6 Special devices marked with an asterisk (*).)
(2) Changing basic instructions (Refer to Chapter 3.3.)
The following basic instructions are converted automatically, but they need to be checked.
Refer to the relevant section and edit them accordingly.
• Converting master control instructions (Refer to Chapter 3.3.2.)
• Converting reset instructions (Refer to Chapter 3.3.3.)
• Converting shift instructions (Refer to Chapter 3.3.3.)
• Converting jump instructions (Refer to Chapter 3.3.4.)
(3) Changing application instructions (Refer to Chapter 3.4.)
Application instructions differ depending on the program type and method, so they cannot be
converted automatically. Even if they can be converted, those containing structures that do not
follow the rules are converted to NOP. Refer to the list in Chapter 3.4 and the programming
manual to convert them into supported application instructions for the FX3 series.
