1.6.4    Advantech WebAccess/SCADA User Accounts

This is not immediately relevant to software installation, but is mentioned here for completeness. Advantech WebAccess/SCADA 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/SCADA 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.
