Testing application on controller

Previous: Transferring application to controller

1. Keep the →perspective Application Testing opened.
   If you want to monitor the value of the variables within the FBD-editor or ST-viewer as well, go to the function block or the program from within the Instances view. This sets the necessary →instance context.

2. In  Values of Variables view, monitor the values and the behavior of the already inserted variables, after the application has been loaded onto the PLC.

   • The variable count starts with value 0. The value is incremented by value 1 (in each cycle).

   • The variable up shows value TRUE and is not changed.

3. Change the value for the variable count of data type INT as follows: Double-click the column Value. In the dialog, enter the new value -200 and click .
   Result: The variable count is still incremented, but increment start is value -200. 

4. Change the value for the variable up of data type BOOL as follows: Double-click the column Value and click  at once. (The BOOL value FALSE is automatically suggested in the dialog.)
   Result: The variable up shows value FALSE. The value of the variable count is decremented by value 1 (in each cycle). 

5. Monitor the values for the variables, while you are stopping and starting the execution resp. the integrated PLC.
   Result: After stopping, the values are not updated anymore. After starting, the variables are displayed/updated again as after loading the application.

   1. In order to stop/start the execution: Click  in the Instances view. Then click  in the Instances view.

   2. In order to stop/start the integrated PLC: In menu PLC, first select the command Stop Built-In PLC. Then select the command Start Built-In PLC (in menu PLC as well).

6. Close the perspective Application Testing: menu Window, command Close Perspective

These steps have concluded the tutorial.
