1.1 Simple Project and Structured Project
■ Simple Project
In a Simple Project, you can create sequence programs using instructions for the Mitsubishi
programmable controller CPU.
The Simple Project offers the same operability for program creation as the conventional GX Developer.
You can create sequence programs using the following programming languages:
● Graphic languages
• Ladder
Use this graphic language to describe programs as ladders consisting of contacts, coils, etc.,
using the same operating procedures as the conventional GX Developer.
•SFC
Use this graphic language to describe sequence control in a way easy to understand.
Describe steps which specify the processing and transition conditions which specify conditions
for proceeding to the next step.
You can describe steps and transition conditions using the ladder language.
● Text language
• ST (Structured Text)
This text language allows you to describe controls by syntax including alternative sequences
offered by conditional sentences and repetition offered by repetition sentences in the same way
as high-level languages such as the C language. Accordingly, you can briefly create programs
easy to look at.
■ Structured Project
In a Structured Project, you can create programs by structured program.
By dividing controls into small portions and making parts of common contents, you can create programs
easy to understand and applicable to many cases (by structured program.)
You can create sequence programs using the following programming languages:
● Graphic languages
• Ladder
Use this graphic language to describe programs as ladders consisting of contacts, coils, etc.,
using the same operating procedures as the conventional GX Developer.
• Structured Ladder/FBD
Structured Ladder is created based on the relay circuit design technology. Because this
language is easy to understand intuitively, it is used generally for sequence programs.
Every ladder always starts from a base line on the left.
Structured Ladder consists of contacts, coils, function blocks and functions which are connected
each other with vertical lines and horizontal lines.
FBD connects functions and function blocks with ruled lines to describe ladders.
•SFC
Use this graphic language to describe sequence control in a way easy to understand.
Describe steps which specify the processing and transition conditions which specify conditions
for proceeding to the next step.
