SCADA:- Supervisory Control And Data Aquisition
First time scada
used in 1960. Scada is a supervisory controller that can control
all your systems and inform about the current information of machine, you can
easily command on machine with the help of scada. In reality, the primary
purpose of SCADA is to monitor, control and alarm plant or regional operating
systems from a central location. While override control is possible, it
is infrequently utilized; however control set points are quite regularly
changed by SCADA. It can well monitor your entire working systems. SCADA systems can be
relatively very easy in use, such as one that monitors environmental conditions
of a small office building, or incredibly complex, such as a system that
monitors all the activity in a nuclear power plant or the activity of a
municipal water system.
Scada is mainly devide in three types:-
- RTU:-Remote Telemetry Units
- Communications
- HMI:-Human Machine Interface
RTU:-
It can collect the information from site and communication bring the
information from different plan and machinery.
HMI:- The
name all ready define it, HMI display the information of machine into display
like permits operator control as required ,archives and data received.
Communication
is used with the help of data cable inside the plant for information sharing;
you can share the desire information with it. We are using fiber optic for
communication.
