Q1: What Is The Scada System?
A1: SCADA (supervisory control and data acquisition) is a system, operates with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station).
Acronym for supervisory control and data acquisition, a computer system for gathering and analyzing real time data. 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. A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the 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. SCADA systems can be relatively simple, 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 or other plants.
Q2: What Is Meant By Plc Scada?
A2: Programmable Logic Controller or PLC is a computing system used to control electromechanical processes. SCADA stands for Supervisory Control and Data Acquisition. It is a type of industrial control system that is used to monitor and control facilities and infrastructure in industries.
Q3: What Is Scada Network?
A3: Acronym for supervisory control and data acquisition, a computer system for gathering and analyzing real time data. 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.
Q4: What Is Meant By Supervisory Control?
A4: Supervisory control is a general term for control of many individual controllers orcontrol loops, whether by a human or an automatic control system, although almost every real system is a combination of both.
Q5: What Are Some Different Levels Of Scada Machines And Systems?
A5: SCADA machines have several different forms. You can have field level devices such as sensors. You can have remote terminal units (RTUs), a main controller or “master station,” or you can have a simple computer system interface that displays data for the user.
Q6: Why Scada Systems Are Implemented?
A6: Some of the reasons or advantages why SCADA systems are implemented are:
- SCADA systems improves the performance of the operation of the plant
- SCADA systems provides better protection to the equipment of the plant
- SCADA systems improves productivity of the personnel
- Information receives very fast, process the information and display it to opertor in graphs and plots. Hence helps the operator to take the decisions fast.
- Provides better energy savings and saves economy.
Q7: Why Do Companies Use Scada?
A7: SCADA is a methodology that defines performance and protection of data for the plant or communication center. It helps improve productivity for employees and helps the economy save energy.
Q8: What Voltage Does An Rtu Operate With?
A8: A remote terminal unit operates at 110V/240V.
Q9: Why Would A Company Want To Use A Plc Over An Rtu?
A9: A programmable logic controller (PLC) is much cheaper and more flexible with programming. PLCs have been replacing RTUs because they are also easier to troubleshoot and have more sophisticated controls than RTUs.
Q10: What is an HMI?
A10: An HMI (human machine interface) is the system that connects to a SCADA database that displays data for the user. The HMI allows the operator to review diagnostic data and trending graphs.
Q11: What is DDE?
A11: DDE is the acronym for dynamic data exchange. DDE provides a communication protocol that allows devices to send and receive communication signals. This protocol was developed by Microsoft.
Q12: What are some advantages of SCADA over other protocols?
A12: SCADA allows users to create object-oriented graphs, they can offer trending graphs to review data in real-time. SCADA also deals with big data, so you can develop a database system that displays trends over a number of years. This allows the business quick access to important data that can be used for future growth and enhancements.
Q13: How does SCADA handle data?
A13: SCADA systems gather data and send them to a central machine that processes the data. The SCADA software is used to manage the data and display it to the user. SCADA also logs information about who runs reports and the data that is used.
Q14: How does SCADA handle issues?
A14: SCADA has an alarm or alert system that interfaces with personnel to send them a warning when a system is not working properly.
Q15: What is the “Historian” in SCADA?
A15: The historian is the name given to the software service that collects events and logs them into the database for future use.
Q16: Different Levels of SCADA?
A16: Different levels are SCADA systems are:
- Field level devices and instruments eg: Sensors
- Remote Terminal Units (RTUs)
- Communication system present between the RTUs and Main Station
- Main Control Station or Master Station
- Computer systems pertained to processing the data for displaying to operator
Q17: Why SCADA systems are Implemented?
A17: Some of the reasons or advantages why SCADA systems are implemented are:
- SCADA systems improves the performance of the operation of the plant
