What must be done to verify a project works correctly after downloading it to a controller?

To verify that a project works correctly after downloading it to a controller, monitoring data and verifying outputs is essential. This process involves checking the actual performance of the system by observing how it operates in real time. By monitoring the data, you can ensure that the controller is executing the programmed logic as intended and producing the expected outputs based on the inputs it receives.

This verification step typically includes using software tools to view live data values and output statuses, allowing for immediate recognition of any discrepancies or issues in the program's functionality. This approach ensures that the controller is functioning properly within the actual operating environment, and that all the programmed parameters are in effect as anticipated.

Other methods, such as recreating the project from scratch or resetting the controller, do not directly assess the performance of the project in action, while running a diagnostics check may provide some insights but does not specifically verify the operational correctness in real-time scenarios. Therefore, monitoring data and verifying outputs serves as the most effective method for confirming that the project is working as intended following download.
