5.6 Developing Simple Project
This chapter provides the overview of simple projects and the development procedure focusing on those specific to Mitsubishi
Electric CNC.
For the user safety sequence, refer to "M800/M80 Series Smart safety observation Specification manual".
For details of the program types that can be used in simple project, refer to "5.2.1 Support Status of Project Types, Program
Types and POUs".
There are two types of simple projects: without labels and with labels. The features of the types are described below.
[Simple project (without labels)]
Simple project (without labels) allows sequence programs to be developed in like conventional GX Developer and built-in edit
function. Labels and FB are unavailable.
[Simple project (with labels)]
Simple project (with labels) enables users to create highly versatile sequence program labels without being aware of devices.
In simple projects (with labels), FB can be used. In an ST language program, FB can be nested within FB up to one layer. In a
ladder diagram program, FB can be nested within FB up to four layers. Programs cannot be input/output in the CSV file
format. For details on labels, refer to "5.10 Creating Label"; for details on FB, refer to "5.11 Creating Function Block".
Reserved characters cannot be used in the file names of simple projects (with labels). Use care when changing projects from
without labels to with labels. For detail on reserved characters, refer to "GX Works2 Operating Manual (Common)".
To create a sequence program using ST language, select simple project (with labels).
