There are three ways to save a MotionWorks IEC Pro project:
1. The normal method of saving a project is saving it as a standard project (project.mwt). This saves the project in a readily useable format, with the main project file called *.mwt and an associated folder with all code, graphical elements, set up files, etc . In this format, the code can be edited and debugged readily, however, it is difficult to share the project with others in this format.
2. When a project is to be archived and / or shared with others, create a zipped project (project.zwt). This format compresses the project, as well as optionally including user and firmware libraries, front-end (compiled) code and graphical page layouts (see the help file in MotionWorks IEC Pro for more information about these options). Before a zwt file it can be used, it must be unzipped using MotionWorks IEC Pro. This will uncompress the project into the .mwt format.
3. In MotionWorks IEC Pro 2.3.0 and higher, a project can be saved as a sealed project (project.zws). This is similar to a zipped project but protects the integrity of the code. A sealed project becomes read only, and allows the programmer to share the project source code with an end user or service technician without fear that the code will be inadvertently changed. Assuming the Sealed Project version is the same as the code originally downloaded to the machine, the user can debug a machine without compiling and downloading. Tools such as Logic Analyzer and debug mode, and read/write recipes and watch window are available. The user CANNOT modify the project, and the project cannot be re-compiled (see the help file in MotionWorks IEC Pro for the complete list of benefits and restrictions of a sealed project).
