1.3.2.1            Centralized Database Server

The Project Node stores and propagates program files, graphic files, run-time files and database files. Connection to the Project Node is not needed for run-time operation of the other nodes. Connection to the Project is needed only for configuration, DRAW and Thin Clients (e.g. PDA and Handheld computers) and the initial connection between clients and SCADA nodes. If the Centralized Data Logger is used for data logging of real-time data, then the Project Node must be connected to the network at all times.

There is usually one Project Node in a system. A Hot Standby can be made easily. There is no Hardkey License required for the Project Node.
