Primary and secondary navigation sidebars
The primary and secondary navigation sidebars (see image below) enable you to drill into the system's functions and parameters and display them in the Main content area.
The primary sidebar always displays on the left-hand side of the application. The secondary sidebar displays only for certain primary navigation selections and appears to the right of the primary navigation sidebar.
Home is the default selection on the primary sidebar. Home displays the system dashboard in the main content area. To view parameters, click a menu item below Home. The parameter information displays in the main content area.
Invalid values
A white arrow in a red circle next to an item on the primary navigation sidebar indicates an invalid value.
To reach the invalid value, click the item and follow the arrows that appear. Edit the value as required.
