We all know SCADA stands for Supervisory Control and Data Acquisition, but most of us confuse that with HMI-Human Machine Interface.
Scada is merely a software where as HMI is a Hardware. The advantage of Scada is we can use a computer, Install the SCADA software and can work it like an HMI as well.
Now coming back Supervisory means something at top level.Control means Controlling something and Data Acquisition means Reading information.
Software used to control hardware(PLC,VFD's,Servo) and acquire data from these devices into computer system.
SCADA- Is a Supervisory control and Data acquisition system. On a SCADA graphics screen after all required pre-configurations all the field parameters (Pressure/ temperature/ Vibration etc) can be seen, alarms/ events can be recorded.
SCADA is an acronym for Supervisory Control and Data Acquisition. SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation. These systems encompass the transfer of data between a SCADA central host computer and a number of Remote Terminal Units (RTUs) and/or Programmable Logic Controllers (PLCs), and the central host and the operator terminals. A SCADA system gathers information (such as where a leak on a pipeline has occurred), transfers the information back to a central site, then alerts the home station that a leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. These systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or very complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system. Traditionally, SCADA systems have made use of the Public Switched Network (PSN) for monitoring purposes. Today many systems are monitored using the infrastructure of the corporate Local Area Network (LAN)/Wide Area Network (WAN). Wireless technologies are now being widely deployed for purposes of monitoring.
Supervisory control and data acquisition
Scada is system for remote monitoring, control and data acquisition. It help us to see what happens in system, it help us in maintenance of equipment, especially motors, pumps and other component when we monitor all the time important values as a current, it give us clear picture of state in system, position of each element, trends and help us in finding out what went wrong when we have some outage.
SCADA STANDS FOR SUPERVISORY CONTROL AND DATA ACQUISITION
WITH THE HELP OF SCADA WE CAN CONTROL AND MONITOR DEVICES LOCATED IN REMOTE LOCATIONS. SCADA INVOLVES HUMAN AND MACHINE INTERFACE SO THAT WE ACCURATELY MONITOR AND CONTROL REMOTE DEVICES.
It is an acronym for Supervisory Control And Data Acquisition. A SCADA system provides remote visibility and control features to a company's assets. i.e. it allows a company to monitor and/or control equipment, that installed at a remote location, from a central location such as a control room.
To monitor the equipment remotely, there needs to be a Remote Terminal Unit (RTU) installed at the remote location which can be controlled from the control room and will take in digital or analogue inputs to monitor and push out digital or analogue signals to control the remote equipment.
SCADA is graphics which you can monitor or control any Industrial Process
Supervisory control and data acquisition.Its a system which is used to moniter and control the PLC.It helps to moniter the oveall process in a plant.
Supervisory control and data acquisition which is designed for remote monitoring and control that operates with coded signals over communication channels
A SCADA Stand for SUPERVISORY CONTROL AND DATA ACQUISTION it Monitors and controls all the coded signals over the field in an industry all the infact scada is a graphical representation of the field instruments and it controls and monitors over it
