Script
This chapter describes the script function, editing and management of the script, definition method, and definition
sample.
1.1 Overview of the Script Function
● What is the script function?
Complex processes such as conditional branching, logical operation, arithmetic operation, functions, etc., can be
programmed in a text format using Script Function.
The scripts can be executed in a Script Command, a Global Script, a ladder program, or a FBD program.
For ladder program and FBD program details, refer to the following.
• Ladder program: SCRPT instruction
F "SmartAXIS Ladder Programming Manual" - Chapter 27 "Scripts"
• FBD program: Script FB
F "SmartAXIS FBD Programming Manual" - Chapter 17 "The script FB"
As an example, the logical product (AND) calculation described as in a ladder diagram is described as
[L M 100] & [L M 101] in text format in the script.
■ Description and management of the script
The script is programmed by WindO/I-NV3 script editor, and managed by Script Manager.
■ Example of using the script
As an example, when reading the data from the external device and displaying on the Touch, the load on the external
device can be reduced for processes such as conditional branching or function calculation, which apply a heavy load
on the external device, by processing it with a script on the Touch.

1 About the Script Function

• By using the Script Editor, conditional expressions, operators, and functions can be described by selecting
them from a list, and an error in the script can also be determined. The script can also be exported as a
text file, so the script can be edited by a text editor such as Notepad, and the edited script can be
imported back into the Script Editor by saving it as a text file.
For details, refer to “2.3 Script Editor” on page 20-8.
• Script Manager can manage the script collectively by adding, deleting, organizing, etc., the script created
by the Script Editor.
For details, refer to “2.2 Script Manager” on page 20-7.
