1. Editing by other tools
The contents of a program (pgm file) is reflected on the mnemonic screen (lst file), but the
contents previously saved on JW-100SP is displayed on the ladder screen (lad file).
Therefore, switch the screen to the mnemonic screen, and press the [Conversion] button to
convert from mnemonic to ladder so that the contents of a program can be reflected on the
ladder screen.
2. Selecting [Save without Conversion] on JW-100SP Version 5.20 and before
Select any of the screens (Ladder/Mnemonic) previously saved which you want to be active, and
press the [Conversion] button, since the contents displayed on the mnemonic screen and the
ladder screen are different.

■ Change 2
When the next program file is opened, a warning message will appear if a verification error occurs
between [pgm file] and [lad file].
・Program file edited and saved by other tools
・Program file saved by selecting [Save without Conversion] on JW-100SP Version 5.20 and be-
fore.
[1] Handling of program files
The following changes are made on Version 5.20 so that you can see in the same way on the Ladder
screen and Mnemonic screen when you opened a program file that was edited by other tools (such as JW-
50SP, etc.)

■■
■ Change 1
A change is made so that the same contents can be saved on [pgm file], [lad file], and [lst file] when a
program file is saved. [Save without Conversion] is removed from the selection items on Version 5.20
and before when a program file is saved.
