True or False: PR data is valid globally through the controller.

The statement that PR (Position Register) data is valid globally through the controller is true because PR data refers to a set of predefined positions that can be utilized across different programs and tasks within the robot controller's environment. This means that once a position register is defined, it can be accessed and utilized by any program that is run on that controller, making it a versatile and efficient way to handle robotic motion and location.

This global accessibility allows for consistent use of position data, ensuring that the robot can accurately reference the same locations throughout various applications and tasks without the need for redefining the positions each time. Such flexibility is essential for programming efficiency and reducing potential errors in robotic operations.

In contrast, the other choices imply limitations on the use of PR data that do not apply; for instance, the assertion that PR data is only valid in specific programs or only for the current task would restrict the overall utility and effectiveness of position registers, which fundamentally contradicts their designed function within the FANUC robot controller framework.
