Stand-alone systems are implemented in one of two general ways:
· The SCADA Node software and Project Node software on the same PC.
· The SCADA Node software on the PC and the Project Node Software on a mobile laptop or remote PC.
Figure 1.7 Stand-alone SCADA Node
This standalone PC would have both the SCADA node software and the Project Node software installed. The Project Node software is the configuration tool. A web browser must be installed on the system to use for the configuration tool (Project Manager). A TCP/IP Service must be installed. The Loop back TCP/IP service in Windows will work (even without a network card. IIS (Internet Information Services) must also be installed as part of the configuration tool.
ViewDAQ is a non-web browser version of VIEW that allows operators and users to View and Control real-time data and full-animation graphics without a web browser. ViewDAQ is intended for local control room applications and runs on the SCADA node.
Displays Groups are a feature available to ViewDAQ users (and browser clients). Display Groups are a "Windows Management Tool" to allow multiple windows to be opened, sized and positioned on the screen, then saved for later recall with a single button click. Examples of Display Groups is to have an Alarm Window, A Trend Window and a Graphic window opened automatically with the selected graphic, trend etc. with a single button click. Display Groups can be created, modified and saved using ViewDAQ (Web browser VIEW clients can only view Display Groups).
Engineers and technicians always use a web browser to configure the database. There is a local version of the Graphics builder on the Project node named DrawDAQ, to allow users to build graphics without a web browser. DrawDAQ is intended for "standalone" architectures where both the SCADA node and Project node software are installed on the same PC.
