This section gives the procedure for creating a project file.
3.3.1

Project Files

A project file is the application file for MPE720 version 7. It includes the following information.
System configura-
tion
Programs
Registers
The project file includes files for all of the above information but allows you to handle them as a
single file in Windows. The project file extension is .YMW7.
Opening a project file enables editing all of these files.
Only one project file can be opened in a single window with MPE720 version 7. The same proj-
ect file cannot be opened in more than one window with MPE720 version 7. If you try to open a
project file that is already open, the window that contains the open project file will move to the
front.
To prevent data loss in case of a CPU Unit/CPU Module failure, always store a backup copy of
Information
the project file. We recommend saving a copy of the project file before making any
modifications to it (changing the module configuration definitions, the ladder programs, the
motion programs, etc.).
• System definitions
• Scan time definitions
• Module configuration definitions
• Data tracing information
• Ladder programs (high-speed, low-speed, start, inter-
rupt, and function programs)
• Motion programs (main program, subprograms, and
group definitions)
• Table data
• Variables (axis, I/O, global, constant, and user-defined
structure variables)
• Comments (I/O, global, and constant comments)
• M (data registers)
• D (internal registers)
• C (constant registers)
• S (system registers)
• I (input registers)
• O (output registers)
• G (data registers)
