The document discusses the technical functions of a SCADA system. It describes data acquisition as the basic function that collects telemetry measurements and status indications from devices like CTs and PTs through RTUs and IEDs. Data is stored in a real-time database and acquired in less than 2 seconds. Other key functions include supervisory control that allows remote control of devices, tagging for authorization of device operations, alarms to notify of events, logging to record operations and alarms, load shedding for automatic or manual load control during emergencies, and trending to plot measurements over time. The SCADA system provides the operator complete visibility of the power system from a central control room.Scada protocols-and-communications-trends

SCADA systems are used to monitor and control industrial processes remotely. They acquire data from sensors in the field through programmable logic controllers (PLCs) or remote terminal units (RTUs), transmit the data to centralized human-machine interfaces (HMIs) over telecommunication networks, and allow operators to send control commands back to the field devices. SCADA systems have evolved from monolithic first-generation systems with standalone computers to distributed second-generation and networked third-generation systems that use open standards and can connect over wide area networks. They provide features like dynamic representation of process data, database connectivity, device connectivity, alarms, trends, scripting, security, recipe management, and networking capabilities.supervisory control and data acquisition system

SCADA systems are used to monitor and control geographically dispersed industrial processes. A SCADA system consists of field devices like PLCs and RTUs that connect to sensors and convert signals to digital data. This data is communicated to a control center via telemetry where it is processed by a data acquisition server and presented to human operators through an HMI. The system allows operators to monitor and control the industrial process. SCADA has evolved from early monolithic centralized systems to modern distributed and networked systems that utilize open standards and protocols to distribute functionality across a wide area network. SCADA is commonly used in applications like power generation, water treatment, oil and gas pipelines, and more.Scada systems automating electrical distribution

Programmable Logic Controllers (PLCs) were developed to control industrial machinery in a programmable and reliable way. A PLC has a processor that executes stored instructions to control inputs and outputs based on ladder logic programming. It includes a power supply, memory to store the user program, and I/O modules to interface with field devices. PLCs offer advantages over hardwired control systems like easier programming, flexibility, and communication capabilities. They are used widely in industrial applications for tasks like sequencing, timing, counting, and analog control.Programmable logic controller (plc)

Here is the short description..
Angina Pectoris is chest pain caused by reduced blood flow to the heart, often due to coronary artery disease. It may feel like pressure or tightness in the chest and can spread to the arms, neck, or jaw. It can be stable (triggered by exertion) or unstable (occurs unpredictably). Treatment includes lifestyle changes, medications, and medical procedures to improve blood flow and prevent complications.

A scattered radiation survey in a radiology department is an essential process for ensuring radiation safety and compliance with regulatory standards. Scattered radiation, which is secondary radiation deflected from its original path after interacting with a patient or other objects, poses a potential hazard to healthcare professionals, patients and general public.
Protection for Healthcare Workers and General Public: Scattered radiation surveys pinpoint areas where scattered radiation levels are highest. This helps in identifying workspaces or equipment where additional shielding or protective measures may be needed.
Since prolonged exposure to scattered radiation increases the risk of conditions like cancer and cataracts, surveys help to ensure that exposure stays within safe limits, adhering to regulatory standards and minimizing long-term health risks. Survey helps to protect Workers and General Public.
Radiation Survey data for safety improvements: The data collected in these surveys allows the X-ray department to make informed decisions about room layout, equipment placement, and workflow adjustments to further reduce exposure.
Surveys help identify where lead aprons, thyroid shields, and lead glasses are most effective, and when extra protective barriers or shields might be necessary for staff safety.
Radiation Survey for image quality: Clear, high-contrast images are essential for accurate diagnoses. When scattered radiation is minimized, the images are of higher diagnostic quality, helping radiologists detect abnormalities and make precise evaluations.

- 1. Overview of Programmable Logic Control (PLC)
- 2. This presentation will allow you to get an understanding of what PLCs are.With this you will be able to recognize PLCsAnd also know the basics on how to use PLCs
- 3. The information I have gathered gives a brief history of evolution of a programmable logic control, or PLC. The reason for changing from relay control systems to PLCs are given in this presentation. The ladder logic language, which was developed to simplify the task of programming PLCs, is introduced.Summary
- 4. ResearchLets start of by giving the definition of a PLC, it is a specialized computer used to control machines and processes.The designs of most PLCs are similar to that of other computers.The PLC is an assembly of solid state digital elements designed to make logical decisions and provide outputs.PLCs are used to control operate manufacturing process equipment and machinery.
- 5. PLCs offer several advantages over relay type controlsIncreased Reliability: once a program has been written and tested, it can be easily downloaded to other PLCs.More Flexibility: It has easier to create and change a program in a PLC than to wire and rewire circuit.Lower cost: PLC were originally designed to replace relay control logic, and the cost of savings have been so significant that relay control is becoming obsolete except for power applications
- 6. Advantages continuedCommunications capability: A PLC can communicate with other controllers or computer equipment to perform such functions as supervisory control, data gathering, and monitoring devices and process parameters, and down load and up load programsFaster response time: PLCs are designed for high speed and real time applicationsEasier to trouble shoot: PLCS have resident diagnostics and override functions that allow users to easily trace and correct software and hardware problems.
- 7. PLCs allow this piece of equipment to work properly
- 8. Components PLC hasThe central processing unit(CPU)The input/output sectionPower supply Programming device
- 9. ResearchA well designed PLC is not usually affected by the electrical noise inherent in most industrial locations.A distinction between PLCs and computers is that the hardware and the software of PLCs are designed for easy use by plant electricians and technicians.
- 10. Five classes of PLCsNanoMicroSmallMediumLargeThe criteria used in categorizing PLCs include functionally, number of inputs and outputs, cost and physical size.
