Creating a Project File
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.
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.
System configura-
tion
•
System definitions
•
Scan time definitions
•
Module configuration definitions
•
Data tracing information
Programs
•
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)
Registers
•
M (data registers)
•
D (internal registers)
•
C (constant registers)
•
S (system registers)
•
I (input registers)
•
O (output registers)
•
G (data registers)
To prevent data loss in case of a CPU Unit/CPU Module failure, always store a backup copy of
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.).
