Operating and access levels

3.2.1 Operating levels
The SEZ220 signal converter has two basic operating levels: They are:
• Info level
• Main menu
The following table contains their properties and identification.
Designation Properties
Info level Use this level to display key plant data as INFO
pages.
Main menu This level is structured as a menu.
It allows you to read data points and/or change
their values.
The two operating levels are always available regardless of the active access level.
The term "data point" is used as a general term for:
• Real data points with a physical connection to the plant, and
• Fictitious data points without direct connection to the plant (defined solely in
software, e.g. setpoints).
All data points are set and read via operating lines on the menu structure. The
operating elements allow you to select, display and set data points (setting
parameter).
The LCD shows all menus as clear text.
Change back and forth between the two operating levels as follows:
