SCADA Communication and Protocols
SCADA software is the most important aspect which runs on the hardware. Earlier SCADA was mostly hardware and less on software. Presently, SCADA is 85% software and 15 % hardware.
Features of SCADA
The important features of SCADA are the following : 1. Alarm Handling 2. Trend Curves Patterns 3. Data Access and Retrieval 4. Computer Networking and Processing Alarms Handling Alarm handling
SCADA Hardware and Software
A SCADA system consists of a number of remote terminal units (RTU) collecting field data and sending that data back to a master station, via a communication system. The master
Functions of SCADA
A SCADA system performs four functions: 1. Data acquisition 2. Networked data communication 3. Data presentation 4. Control These functions are performed by four kinds of SCADA components: 1. Sensors
