Supervisory control and data acquisition SCADA is a control system architecture that uses computers, networked data communications and graphical user interfaces for high level process supervisory management, but uses other peripheral devices such as programmable logic controllers and discrete PID controllers to interface to the process plant or machinery. The operator interfaces which enable monitoring and the issuing of process commands, such as controller set point changes, are handled through the SCADA supervisory computer system. However, the real time control logic or controller calculations are performed by networked modules which connect to the field sensors and actuators. The SCADA concept was developed as a universal means of remote access to a variety of local control modules, which could be from different manufacturers allowing access through standard automation protocols. In practice, large SCADA systems have grown to become very similar to distributed control systems in function, but using multiple means of interfacing with the plant. They can control large scale processes that can include multiple sites, and work over large distances. It is one of the most commonly used types of industrial control systems, however there are concerns about SCADA systems being vulnerable to cyberwarfarecyberterrorism attacks. The SCADA concept in control operationsedit. Functional levels of a manufacturing control operation. The key attribute of a SCADA system is its ability to perform a supervisory operation over a variety of other proprietary devices. The accompanying diagram is a general model which shows functional manufacturing levels using computerised control.

Briefly, a boot loader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to an. Referring to the diagram,Level 0 contains the field devices such as flow and temperature sensors, and final control elements, such as control valves. Gta 4 Pc Requirements Recommended. Level 1 contains the industrialised inputoutput IO modules, and their associated distributed electronic processors. Level 2 contains the supervisory computers, which collate information from processor nodes on the system, and provide the operator control screens. Level 3 is the production control level, which does not directly control the process, but is concerned with monitoring production and targets. Level 4 is the production scheduling level. Level 1 contains the programmable logic controllers PLCs or remote terminal units RTUs. Level 2 contains the SCADA software and computing platform. The SCADA software exists only at this supervisory level as control actions are performed automatically by RTUs or PLCs. SCADA control functions are usually restricted to basic overriding or supervisory level intervention. For example, a PLC may control the flow of cooling water through part of an industrial process to a set point level, but the SCADA system software will allow operators to change the set points for the flow. The SCADA also enables alarm conditions, such as loss of flow or high temperature, to be displayed and recorded. A feedback control loop is directly controlled by the RTU or PLC, but the SCADA software monitors the overall performance of the loop. Levels 3 and 4 are not strictly process control in the traditional sense, but are where production control and scheduling takes place. Data acquisition begins at the RTU or PLC level and includes instrumentation readings and equipment status reports that are communicated to level 2 SCADA as required. Data is then compiled and formatted in such a way that a control room operator using the HMI Human Machine Interface can make supervisory decisions to adjust or override normal RTU PLC controls. Chinese New Year Seaweed Cracker Recipe. Data may also be fed to a historian, often built on a commodity database management system, to allow trending and other analytical auditing. SCADA systems typically use a tag database, which contains data elements called tags or points, which relate to specific instrumentation or actuators within the process system according to such as the Piping and instrumentation diagram. Data is accumulated against these unique process control equipment tag references. Examples of useedit. Example of SCADA used in office environment to remotely monitor a process. Both large and small systems can be built using the SCADA concept. These systems can range from just tens to thousands of control loops, depending on the application. Example processes include industrial, infrastructure, and facility based processes, as described below Industrial processes include manufacturing, Process control, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes. Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electric power transmission and distribution, and wind farms. Facility processes, including buildings, airports, ships, and space stations. They monitor and control heating, ventilation, and air conditioning systems HVAC, access, and energy consumption. However, SCADA systems may have security vulnerabilities, so the systems should be evaluated to identify risks and solutions implemented to mitigate those risks. SCADA system componentsedit. A SCADA schematic overview showing control levels 0, 1 and 2. A SCADA system usually consists of the following main elements Supervisory computerseditThis is the core of the SCADA system, gathering data on the process and sending control commands to the field connected devices. It refers to the computer and software responsible for communicating with the field connection controllers, which are RTUs and PLCs, and includes the HMI software running on operator workstations. In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites. To increase the integrity of the system the multiple servers will often be configured in a dual redundant or hot standby formation providing continuous control and monitoring in the event of a server malfunction or breakdown. Remote terminal unitseditRemote terminal units, also known as RTUs, connect to sensors and actuators in the process, and are networked to the supervisory computer system. RTUs are intelligent IO and often have embedded control capabilities such as ladder logic in order to accomplish boolean logic operations. Programmable logic controllerseditAlso known as PLCs, these are connected to sensors and actuators in the process, and are networked to the supervisory system in the same way as RTUs. PLCs have more sophisticated embedded control capabilities than RTUs, and are programmed in one or more IEC 6. PLCs are often used in place of RTUs as field devices because they are more economical, versatile, flexible and configurable. Communication infrastructureeditThis connects the supervisory computer system to the remote terminal units RTUs and PLCs, and may use industry standard or manufacturer proprietary protocols. Both RTUs and PLCs operate autonomously on the near real time control of the process, using the last command given from the supervisory system.
