1.2.2   Network Architecture Drawings

Networking is built into the design of WebAccess.  The basic components of WebAccess are:

SCADA Node - which connects to Automation Hardware and makes data available to network

Project Node - which is a centralized database server used by the configuration tool. Thin Clients use the Project node to view static snapshots of animated graphics.

Clients - Which display real-time data with animated graphics and allow operators to change values, acknowledge alarms and control in real-time. Clients connect directly to a SCADA node to get real-time data.

Thin Clients - which display snapshots of graphics and use a text based interface to change data, acknowledge alarms and control.
