Action: WriteVariable - creating a raising edge
Action: CompareVariable - state changed to producing
Action: WriteVariable - stop button
Action: CompareVariable - check state is stopped
Action: CompareVariable - check state is standby
Action: WriteVariable - simulate error occurrence
Action: CompareVariable - check error state
Action: WriteVariable - clear the error
Action: CompareVariable - check state change to initial
Action: CompareVariable - state is again standby
Cleanup: Reset the application, logout and close the project
Action: ResetApplication - reset application
Action: Logout - log out of CORE
Action: CloseProject - close the project
Test execution: Save the test script and press on the green play button to execute the full test script.
