If you’ve worked industrial automation. So in this article I’m going to give you a high-level overview about SCADA. Gaining an understanding of SCADA systems is crucial to appreciating its function in industrial automation, which guarantees effectiveness, dependability, and peak performance in a variety of industries.

SCADA Abbreviation/ Overview  

SCADA Stands for Supervisory Control and Data Acquisition, is a combination of hardware and software used in industrial sector. SCADA systems help monitor and control processes of heavy machinery which I used in different industrial areas and also collect, record and analyze data in real time.

EXPLANATION

SCADA systems monitor the sensors that operate the heavy machines like motors, pumps and valves to an onsite or remote server. Once collected, that sensor data can either be acted upon directly through the use of SCADA software, or saved for later review. In addition to remote data access, users can interact with the SCADA system on-site through operator workstations, Human Machine Interfaces, HMIs, or directly on the SCADA server itself. SCADA helps users make smarter decisions, improve efficiency. It’s used in industries, including manufacturing sectors, oil and gas operations and power grid management.

Remote Terminal Units, RTU’s, or Programmable Logic Controllers, PLCs, are often put in place to serve as local collection points for gathering sensor information and sending it to the SCADA server or HMI. SCADA software then takes over to help you interact with your facility, alert you to issues, inform predictive maintenance and provide control over a handful, or thousands of pieces of equipment. Here at On Logic, we’ve partnered with the SCADA experts at Inductive Automation, makers of the popular and powerful Ignition SCADA software. Our line of hardware with Ignition on board can help you get up and running with a SCADA solution more quickly by combining reliable hardware designed for industrial environments with software specifically developed to streamline modern SCADA implementations. With the amount of data being produced in modern industrial facilities, the opportunity for optimization has never been greater. The concept of collecting and acting on data isn’t new, but today’s SCADA solutions offer incredible insights and capabilities that were previously inaccessible.

Main Functions of SCADA

• Data collection: Compiles data in real time from field devices and sensors.
• Process Control: Issues commands to machinery and equipment to regulate operations.
• System Monitoring: Provides live data visualization and alarm notifications.
• Alarm and Event Handling: Detects and reports anomalies in system performance.

SCADA System Architectures

 1. Distributed SCADA: Multiple control centers operating in a decentralized setup.

 2. Centralized SCADA: A single control center overseeing all operations.

 3. Hybrid SCADA: A blend of centralized and distributed configurations.

SCADA Protocols

 1. Modbus

 2. DNP3

 3. IEC 61850

 4. IEC 60870-5-101

 5. OPC-UA

Advantage and disadvantage associated with an e scalar system:

Advantage:

so first we will see advantage of an scalar system so first advantage is it has user-friendly interface so it is very easy to work on a scale of software it is capable of doing real-time supply or demand calculations by using a SCADA system we can do online complex electrical network analysis as we learn the SCADA system we are using basically for controlling and monitoring and Process and it is providing the automatic control and the response of the SCADA system is very quick.

Disadvantage:

Disadvantage of a SCADA system chances of external interference the high initial cost it increased the unemployment rate.

Application:

now we will see application of SCADA system in real-time world so basically a SCADA is mostly used in electrical power generation transmission and distribution electric utilities use SCADA system to detect current flow and line voltage and to monitor the operation of circuit breaker and to take sections of the power grid on or off line water and sewage stay in municipal water use SCADA to monitor and regulate water flow reservoir levels pipe pressure and for other sectors.

Next application is in manufacturing SCADA system manage parts list for just-in-time manufacturing regulate industrial automation and robots process and quality control next application of E SCADA is mass transit authorities use scatter to regulate electricity to Subway’s trams and trolleybuses to automate traffic signals for rail system to try and locate trains and buses meant to control railroad crossing gates.

Next application of his is at traffic signals scanner regulates traffic lights control traffic flow and detects out of order signal buildings facilities and environments application of SCADA system facility managers use stead of to control HVAC refrigeration unit lighting an entry system.
