The SCADA node has its own run-time database and all graphics. It runs independently of the Project Node, Clients and any other SCADA node. All graphic files, database files, and program files required for run-time operation reside on the local hard drive of each SCADA node.
Each SCADA node communicates to automation equipment using the communication drivers supplied with WebAccess. SCADA nodes also provide Alarming, Logs, Reports, Calculations and other SCADA features.
