Tag
Database
This
is the central database where you specify which hardware is
attached, and what inputs and outputs, or tags, are defined. Once the
tags are defined (as register or coils) and their attributes
selected, the tags can be used in the application on screens, tasks,
alarms etc.

Creating
Screens
Screens
are the most important part of any application as it displays the
information required by the operator. Up to 65536 screens can be
defined in HMI Studio with optional password protection.
