The field devices however fall outside the scope of SCADA in this manual and will not be discussed further.The quickest and easiest is to use AdvancedHMI. It should be noted in passing that many operators judge a SCADA system not only by the smooth performance of the RTUs, communication links and the master station (all falling under the umbrella of SCADA system) but also the field devices (both transducers and control devices). Each RTU/PLC maintains and collects data pertaining to its process areas.Today hardware reliability is less of a problem, but the increasing software complexity is producing new challenges. Server computer performs all of the communications with the PLCs and RTUs on the SCADA network.

Whereas in modern days we have individual advanced systems like PLC, DCS as control systems and use SCADA for operator interface or called as Human Machine Interface (HMI) or simply as graphical user interface. In large telemetry systems, sub-master sites gather information from remote sites and act as a relay back to the control master station.NOTE : In olden days, we call the SCADA system as complete control system with hardware and software to monitor and control the equipment in industries. The master station (and sub-masters) gather data from the various RTUs and generally provide an operator interface for display of information and control of the remote sites. This communication system can be radio, telephone line, microwave and possibly even satellite.Specific protocols and error detection philosophies are used for efficient and optimum transfer of data. The communications system provides the pathway for communications between the master station and the remote sites. It includes a range of drivers and visual.The RTU provides an interface to the field analog and digital signals situated at each remote site.

The data highway is normally capable of fairly high speeds.Another variant of SCADA components widely used is the Programmable Logic Controller (PLC). A closely integrated set of operator interfaces (or man machine interfaces) is provided to allow for easy system configurations and operator control. DCS systems have evolved into systems providing very sophisticated analog (e.g. In addition there has been a growing trend to use smart instruments as a key component in all these systems.Distributed control system (DCS), is another variant of SCADA where data acquisition and control functions are performed by a number of distributed microprocessor-based units situated near to the devices being controlled or the instrument from which data is being gathered. As complete control system.SCADA technology has existed since the early sixties and there are now two other competing approaches possible – distributed control system (DCS) and programmable logic controller (PLC). Below we discuss about the SCADA systems in terms of olden days i.e.

1930’s Check Before Operate (CEO)Systems, Based on Electro Mechanical Technology 1890’s Remote Control and Remote Indication They are often used in the implementation of a SCADA RTU as they offer a standard hardware solution, which is very economically priced.

Intermediate data acquisition station: are input blocks of RTU remote terminal ( Remote Terminal Units ) or PLC ( Programmable Logic Controllers ) programmable control blocks with delivery function relay with actuators (field level sensors, switchgear control boxes and actuator valves …). Central monitoring control station: is one or more central servers ( central host computer server ). Automation:: Automatic tasks of switching of transmission lines, CBs, etc.The important benefits can be addresses as the following functions:The structure of a SCADA system has the following basic components (Figure 1):

Electric power generation, transmission and distribution: Electric utilities use SCADA systems to detect current flow and line voltage, to monitor the operation of circuit breakers, and to take sections of the power grid online or offline.2. Typically, SCADA systems are used to automate complex industrial processes where human control is difficult.For example in systems where there are more control factors unable to be managed by operators in a control center.SCADA systems are widely used for control in the following domains1. Human interface – HMI machine ( Human – Machine Interface ): is the device that displays the data processing process for the operator to control the operation process of the system.The important functions of an SCADA are listed below.SCADA can be used to manage any kind of equipment.

Discover and eliminate bottlenecks over time and improve efficiency Measure trends over time and prepare reports and charts Detect, Diagnose and correct problems as soon as they arise Acquire quantitative measurements immediately and over time SCADA is capable of the following

With SCADA, you can do more, at less cost, providing a direct increase in profitability.If you liked this article, then please subscribe to our YouTube Channel for PLC and SCADA video tutorials.You can also follow us on Facebook and Twitter to receive daily updates. With such am=n ability it is possible to correct errors and diagnostics.So even for very complex manufacturing processes, large electrical plants, etc., you can have an eagle-eye view of every event while it’s happening — and that means you have a knowledge base from which to correct errors and improve efficiency. GIS (Geographical Information System) is one such software widely used in electric power applications. As SCADA technology improves, more sensors can be placed to improve efficiency.SCADA has the ability to view the operation of large power process in real time through software. Sensors can be placed at every critical point in the process to be managed and controlled.
