interface. When working in the FactoryTalk Historian ME web interface, you can re-

your browser toolbar to show current status information.
The CPU usage percent listed under the System Status section on the left-hand side
may display a different percent than what is listed under CPU and Processes in the

periodically while the CPU usage listed in the main window is static. It does not
change once the page is loaded.
