●
Types of scripts
There are 3 types of scripts used.
■ Script Command
This is a script that executes in accordance with trigger conditions in the same way as other parts, such as switches or
lamps, for each screen.

• Multiple scripts can be set for each screen.
For details, refer to Chapter 12 “5 Script Command” on page 12-32.
■ Global Script
This is a script that operates within the whole project. This script is executed at the end of MICRO/I scan process in
accordance with the trigger condition. The amount of Global Scripts which can be used in a project is as follows. For
details about setup, refer to “3 Global Script” on page 20-12.

Only one cyclic script can be set to a project.
