ANALOGY SCADA SYSTEM 1. Working Procedure of SCADA system 1.2 The SCADA system performs the following functions: 1.2.1 Data Acquisitions 1.2.2 Network Data Communication 1.2.3 Information/Data presentation 1.2.4 Monitoring/Control 1.2.a These functions are performed by Sensors Collect important information Remote Terminal Unit Sends information to controller Controller Displays the status of the system Communication network Backbone; conduit for data transmission between the central control station and remote field devices 1.2.b According to the system's status, the user can give commands to other system components. Which, the communication network does this 1.2.1 DATA ACQUISITIONS 1.2.1a. Real-time system consists of thousands of components and sensors. 1.2.1b. It is important to know the status of components and sensors. Example, some sensors measure the water flow from the reservoir to water tank and some sensors measure the value pressure as the water is release from the reservoir. 1.2.2 DATA COMMUNICATION/ NETWORK DATA COMMUNICATION 1.2.2a. The SCADA system uses a wired network to communicate between users and devices. The real-time applications use lot of sensors and components which should be control remotely.  1.2.2b. The SCADA system uses internet communications. 1.2.2c. All information is transmitted through the internet using specific protocols. 1.2.3 INFORMATION/DATA PRESENTATION 1.2.3a The normal circuit networks have some indicators which can be visible to control but in the real-time SCADA system. 1.2.3b There are thousands of sensors and alarm which are impossible to be handled simultaneously. 1.2.3c The SCADA system uses human-machine interface (HMI) to provide all of the information gathered from the various sensors A. HUMAN MACHINE INTERFACE A.1 The information is displayed and monitored to be processed by the human. A.2 HMI provides the access of multiple control units which can be PLCs and RTUs. A.3 The HMI provides the graphical presentation of the system. 1.2.4 MONITORING/CONTROL 1.2.4a The SCADA system uses different switches to operate each device and displays the status at the control area. 1.2.4b Any part of the process can be turned ON/OFF from the control station using these switches. 1.2.4c SCADA system is implemented to work automatically without human intervention but at critical situations it is handled by man power.  2. ADVANTAGES OF SCADA SYSTEM 2.1 The SCADA system provides onboard mechanical and graphical information. 2.2 The SCADA system is easily expandable. We can add a set of control units and sensors according to the requirement. 2.3 The SCADA system's ability to operate in critical situations. ALL ABOUT SCADA (Supervisory Control and Data Acquisition) 1. These are advanced computer-based systems used to monitor and control industrial processes. 2. Essential part of operations and can be found in a wide range of industries, from manufacturing to energy production, providing (a) real-time insights into the status of operations and helping to ensure that they run smoothly and efficiently. a.1 Status of a wide range of processes, allowing operators to make quick, informed decisions based on the most recent information at hand. 3. Essential for the modern industrial landscape. 4. Also provide an invaluable benefit in that they allow for remote monitoring and control of processes from virtually any location in the world, enabling operations to stay connected with their processes even when physically removed. 5. (a) Advances in technology and automation have vastly improved the capabilities of Supervisory Control and Data Acquisition (SCADA) systems and they are becoming increasingly popular for a multitude of applications such as predictive maintenance, energy management, asset tracking, monitoring industrial processes, and even remote control of machinery. a.1 These systems can be used to enhance the security of data networks with real-time monitoring and alerts. 6. Industrial Automation systems are composed of three main components working in tandem: 6.1 Human Machine Interface 6.1.a Acts as the brain of the system and allows operators to interact with the entire system.  6.1.b Provides an intuitive graphical user interface for operators to interact with the system and control its various components. 6.2 Remote Terminal Unit 6.2.a Acts as a gateway between field devices and main controllers. 6.2.b Used to collect and transmit data from sensors in the field back to the main control system 6.3 Programmable Logic Controller 6.3.a A computer-controlled device that processes data using programmable logic instructions. 6.3.b Digital computers are used to control industrial processes and are responsible for monitoring, controlling, and automating various devices based on input from sensors or operators. This combination of components allows businesses to manage their industrial operations efficiently and cost- effectively. HISTORICAL RECORDS 1. It refers to a project operation where the value of the variable changes and the process of recording these changes. 2. It directly reflects the situation of engineering operation 3. Research and analysis of the data of historical records is helpful to improve the projects to improve the production efficiency and quality  4. History of the CONFIGURATION SOFTWARE: Timing records Numerical value that records the engineering variable at a specified time interval Trigger records Binds trigger variable and select trigger mode, once triggered it can record the value of engineering variable Changing records Are recorded when the value of the variable is recorded RECORDING CONFIGURATION 1. Database type 1.a There one type database type: file database 2. Data storage location 2.a There are three methods for data storage location: "internal storage", "SD card", and "U disk". 2.b Set the data storage method as required. 2.c For the setting of the storage file size, when the stored data file is greater than the set value, a new storage file will be automatically created. 2.d After configuring the database type, data storage location, and data file size of the storage file, click "OK" to complete the configuration of the historical record.
