Rockwell ControlLogix Programmer Certification Practice Test

The operating mode of the controller in Studio 5000 Logix Designer can be found in the Online Bar. This feature provides real-time feedback on the status of the controller, including its operating mode, which can be either "Run," "Program," or "Remote." The Online Bar is typically located at the top of the workspace and offers a quick overview of the current status, making it easy for programmers and engineers to identify how the controller is operating at any given moment.

In contrast, the Results Window displays the outcome of compile and verification processes but does not show the controller's operational status. The Help System provides information and guidance on using the software but does not display current operational parameters. The Controller Organizer is used for managing and navigating the project's structure but does not indicate the actual running mode of the controller. Thus, the Online Bar is the correct and most accessible location to check the operating mode of the controller in this development environment.
