The Check In dialog box appears.

11.In the Comment field, enter Basic Configuration.

12.Click OK.

13.In the Model view, assign the PLCSim instance to the ControlSystem area.

14.In the Deployment view, host the PLCSim instance in AppEngine1.

15.Right-click on PLCSim and select Deploy.

16.Keep the default options and click OK.

17.When the Deploy progress displays 100% completed, click Close.

View the Attributes in Runtime

You will now return to Object Viewer to view the attribute values in runtime.
