Compare PLC Programs

KAS provides a tool to show the differences between the "Local Project" and the project currently on the Controller or another project file.


    • To compare project files, use the Compare Projects function from the File menu.
    • The function for comparing the local project file to that on the controller is accessed from a button on the Status Bar, between the Local and Controller versions. It is active when KAS is connected to a controller.
      Difference in Local and Controller Versions

Once files have been selected to compare, a window opens listing the components of each project, and any differences between them. How the projects differ is color coded.. Red item indicates where there is a mismatch. Double-click to open an item. The << button brings you back to the list.


Figure 4-68: Listing the Differences

The following message will be shown if you click on the compare button but the project is not present on the controller.
