5.6.1 Overview of Simple Project

The configuration of a simple project is as follows. Global label and local label are available only when simple project (with
labels) is selected when the project is created.
Project
Item
Sequence programs Sequence program (user PLC) for Mitsubishi Electric CNC
Defines PLC messages such as alarm messages and PLC switches.
PLC messages can be used only in ladder diagram.
PLC message data PLC messages cannot be used only in ST language.
To use a PLC message in the sequence program created in ST language, it must be written
by using some text editor. Otherwise, use a PLC message created in ladder diagram.
Comment for devices in sequence programs.
There are two types: project-common "Global Device Comment" and program-specific "Local
Device comments device comment".
To change the settings, open [Tools] - [Options] window and select [Program Editor] - [All Ed-
itors] - [Device Comments].
Parameter Set the use range of devices and order of sequence program execution, etc.
Global label Label variable that becomes valid for all sequence programs when multiple sequence pro-
(with labels only) grams are create in a project.
Local label Label variable that becomes valid only in each sequence program.
(with labels only) This is one-on-one setting with an individual sequence program.

5.6.1.1 Symbolic Information

Symbolic information is data storing program configuration such as labels and FB. To read or write labels and FB to the CNC
controller, read or write symbolic information.
