To monitor the live values of the tags configured in the runtime mode of the program, which option would you select?

Monitoring live values of tags configured in the runtime mode allows an operator or programmer to observe the current state of various data elements during program execution. The option to "Monitor tags" is specifically designed for this purpose. It enables users to view real-time information, ensuring they can analyze the behavior of the application as it runs and make any necessary adjustments.

This option provides a straightforward interface for tracking changes and values associated with tags, which is critical during troubleshooting and performance tuning. It allows for immediate insight into the system, making it easier to verify the correct functioning of the logic and diagnose any issues that may arise.

The other options focus on different functionalities: "Edit Tags" would allow for modification of tag values rather than monitoring live data, while "Controller Tags" and "User-defined tags" refer to specific categories of tags but do not imply the ability to monitor live values in the way that "Monitor tags" does. Each of these other choices serves a distinct purpose that does not directly address the need for real-time observation of tag values.
