Access Control

The access control can be accessed in the menu bar via the highlighted button. Depending on the current setting, the button is labeled Disabled, Locked, Operator, Service, or Master.

The access control of the EasyNOₓ serves to protect sensitive data and functions. When access control is disabled, there are no restrictions with the exception of the NOX monitor views. With enabled access control (see section Enabling/Disabling Access Control), four access levels with different rights are available (see table below). Note that the NOX monitor views can only be opened when access control is enabled, and you need at least the rights of the access level Operator to open these views.
