What is the primary function of the System/Config screen on a FANUC controller?

The primary function of the System/Config screen on a FANUC controller is to configure system settings and alarms. This screen provides users with access to various configuration options that allow for the adjustment of the controller's parameters, such as communication settings, system options, and alarm management.

Configuring system settings is critical for ensuring that the controller operates correctly and efficiently for the specific application it is being used for. Users can customize settings related to the robot's operation, safety parameters, and connectivity with external devices. Additionally, managing alarms is essential, as it helps users quickly troubleshoot issues that may arise during operation, allowing for timely maintenance and minimizing downtime.

The other choices pertain to functionalities that, while important, do not reflect the primary purpose of the System/Config screen. Programming robot movements and monitoring performance are typically handled through different interfaces or screens specifically designed for those tasks, while storing program files is related to data management functions independent of system configuration.
