Which device mode locks out all editing or monitoring capabilities?

Run Mode is the state in which a ControlLogix system executes the user program but prevents any changes to the program or monitoring capabilities in a standard manner. When the controller is in Run Mode, it is actively processing the logic as written, and to ensure system integrity and performance, editing or modifying the program while it is running is locked out.

This design is precautionary as it helps to avoid accidental changes that can disrupt the real-time operation of the system. Users can, however, switch to Program Mode to modify the program when necessary, but in Run Mode, the focus remains on maintaining the stability and reliability of ongoing operations.

Other modes, such as Program Mode, allow for editing and configuration, while Remote Mode typically refers to controlling or interacting with the system from a remote interface. Control Mode is not a standard designation in ControlLogix systems, making it less relevant in this context. Thus, Run Mode stands out as the mode that ensures the protection and continuous operation of the system by locking out editing and monitoring capabilities.
