Simplified configuration mode does not remove any functionality or setting from the
device. It only controls the view or display of the settings. All the settings made in Regular
configuration mode are still applied during simplified mode (they are either hidden or
read-only). Therefore, simplified configuration mode can also be viewed as locking
advanced setpoints.
Configuration mode is applicable to the "Setpoints" items only and does not control view/
presentation to other Main menu items, such as Device Definition, Status, Metering,
Records, Commands and Maintenance. The configuration mode setting is available to be
changed by the "Administrator" role. The configuration mode control is applicable to
device HMI and setup software, as well as online and offline setting files.
Configuration mode does not disable the device functionality or settings. It only controls
the view or presentation on the HMI and setup software screens. Therefore, settings which
are hidden or Read-only are preserved and applied within the device.
The homepage shows the home icon which changes color according to the configuration
mode. When in Simplified configuration mode, the home icon color changes to green.
When in Regular mode, the home icon color stays blue.
Example 1: More about the setting items view control
The Phase TOC 1 function in Regular mode has 14 setpoints made available to edit (read-
write). In the case of Simplified mode this function has only 6 out of the 14 setpoints made
available to edit (read-write), 5 setpoints are hidden, and 3 setpoints are read/view-only.
All setpoints under Regular mode are still applied and used by the device. For example the
"Input" is hidden but configured as "Phasor" during Regular mode, therefore Phase TOC 1
still applies "Phasor" as an input. Similarly, "Reset" is read-only, and Phase TOC 1 still
applies "Instantaneous" for resetting. The read-only settings are greyed out.
