This is not immediately relevant to software installation, but is mentioned here for completeness. Advantech WebAccess User types restrict access to the Project Manager, Graphics and Tags. User types restrict access to displays through a Web Browser, not to ViewDAQ. Area and Level security applies to all users. A User can be given access to all nodes in a project or only a few.

Using the local ViewDAQ on the SCADA node (i.e. the Advantech WebAccess icon on the taskbar) all users can access all displays and tags and use the graphics builder including the Graphic Download feature. All project configuration is done through a Web Browser; only the Administrator or Project Users can configure the Database.
If a Web-browser user tries to change the value of a Tag without correct security Level or Area, a Popup Dialog box will prompt for User Name and Password, similar to local ViewDAQ. The difference is that this does not Login the new user name. This enables a "one shot" opportunity to change the selected tag. After the tag is changed, the Area or Level and user login reverts to the original user.
There is one Administrator account: admin. The administrator can configure database, build graphics through web browser and view any graphic in VIEW (run-time). The Administrator account applies to all SCADA nodes and all projects. Additional Users with "Administrator" capabilities can be configured by a combination of "Project User" and "Power User".
DrawDAQ is available only on the Project node (or a standalone system that has both Project and SCADA node software installed). Any local user can use DrawDAQ.
ViewDAQ is available only on the SCADA node (or a standalone system that has both Project and SCADA node software installed). Any local user can use ViewDAQ to view any graphic. Area & Level restricts which tags the user can change in ViewDAQ.
