SCADA

                Supervisory Control and Data Acquisition or SCADA is an automation control system used in industries such as energy, oil and gas, water power and many more.

        The system has a centralized system that monitors and controls the entire country from industrial plants to plant premises.

            The SCADA system works by working with signals that communicate through channels to provide the user with remote control of any device in a system.

       There are some essential parts composed of highly controllers and monitoring Systems.

1. SCADA system human machine interface or HMI supervisory system remote terminal units

2. RTu  use programmable logic controllers or PLC and communication infrastructure.

HMI processes the data and sends it to the human operator. Where they can monitor or control the system.





         The supervisory system collects data and sends orders or operations to the process. RT uses sensors and converts their signals into digital data and sends it to a supervisory system where it can be stored in a distributed database.



                   PLCs are used as field devices because they are so much more versatile and economical than the processed ones used.

        Finally the communication infrastructure distributes to the supervisory system and then to RT usage and pluck to command the user.

          The use of communication infrastructure is necessary to relay data to remote and PLCs that run along the electric grid water supply and pipeline communication is the most necessary link for a SCADA system,

  In order to operate properly however the system uses the art from HMI to manage how well communications and PLC fundamentally determine how successful a SCADA system can be.

        SCADA systems are important for industrial organizations because they help maintain efficiency process data for the smarter.

Introduction to CSS,Typography

By Prathima
  Introduction to CSS What is CSS? CSS (Cascading Style Sheets) is used to control the style and layout of web pages. It allows you to separate content (HTML) from presentation, enabling better design consistency and easier maintenance. Why Use CSS? Enhances the visual appearance of websites. Makes websites responsive for different devices. Reduces duplication by centralizing styles. Enables consistent design across multiple pages. Types of CSS 1.      Inline CSS o     Applied directly to an HTML element using the style attribute. o     Use When: You want to apply a unique style to a single element. Example: html Code start here <p style="color: red; font-size: 16px;">This is an inline-styled paragraph.</p> 2.      Internal CSS o     Defined within a <style> tag in the <head> section of the HTML document. o  ...

Plc (Programmable Logic Controller) Communication/PLC communication protocols/Ethernet/IP

By Prathima
Plc (Programmable Logic Controller) Communication/PLC communication protocols. A program consists of 1 or more instructions that accomplish a task. Before writing the program in plc you'd wish to attach the module with PLC software by using communication port like RS232,Serial Communication,Modbus or Ethernet supported your application. you'd wish to offer the connection to all or any or any your input and out devices, Then you've to write down down the program in plc.. Ladder Logic is that the normal programming language . There are four basic steps within the operation of all PLCs; Input Scan, Program Scan, Output Scan, and Housekeeping. These steps continually happen during a repeating loop.        The communication protocol acts as an agreement between two or more communicating Devices. Extension modules PLC I/O number are often increased through certain additional modules by system extension through a extension lines. In PLC Each module can con...
