The architecture of Rapid SCADA is multi-tier and distributed (see Figure 1). Applications can run on a single server or multiple computers across a network. Controllers can use communication channels of different types for connecting to a system. Major factors that determine the system configuration are number of equipment locations, distance between them, estimation of end-user activity, restrictions of external systems.
Rapid SCADA includes the following main applications:
- Webstation is a web application that displays information to a dispatcher via browser in different forms (tabular, schematic, diagrams, reports) and provides sending commands.
- Server manages the data archives, performs mathematical calculations and provides information to the client applications.
- Communicator interacts with controllers, transmits data to Server application.
Providing data access using web technology significantly simplifies the deployment and maintenance of the system, which is especially important for a large number of users.
Commonly used devices controlled by a system are electricity meters, heat meters, fire and security alarms, access controllers and other equipment.
