You can command items in the Commissioning mode and Simulation mode. You must be in Test mode to issue commands while commissioning. The controller goes offline and the field point appears as well as the value sent using the Commands option. The commands you perform in Test mode are temporary. The Tool releases these commands when you leave Test mode in Commissioning mode. The controller goes online, and the point value returns to its value. When you are working in the Commands dialog box, the software does not poll for data or updates until you exit the window. Polling immediately resumes after closing the Commands dialog box. See Commanding Items in the Simulating a System section.
