Basics Of PLC Overview 8. ProssecerMemoryunit Power Supply unit Input/Output Module Programming unit 9. CPU: Its the unit containing the microprocessor. Power supply unit:Its needed to convert the mains A.C. voltage to low D.C. Voltage(Normally Internal) 10. Input-output sections: are where the processor receives information from external devices and communicates information to external devices. 11. Expansion Modules: The S7-200 PLCs are expandable. Expansion modules contain additional inputs and outputs. These are connected to the base unit using a ribbon connector. 12. Memory unit: is where the program is stored that is to be used for control actions. Programming device: is used to entered the required program into the memory of the processor. 13.

PLC Operation:1.The PLC program is executed as part of a repetitive process referred to as a scan. 2. Scans:- :Left to Right Top to Bottom 3.Scan cycle:- 800-1000scan/sec 16. Example: The Ladder Diagram 17. Selecting a PLC: Criteria: Number of logical inputs and O/P. Memory. Number of special I/O modules Scan Time. Communications. Software. 18. HMI (Human Machine Interface) is a medium for information exchange and mutual communication between electromechanical system's and the user. It allows the user to complete settings through touchable images or keys on the user-friendly window. This not only offer's fast and convenient control of manufacturing automation, but also has replaced traditional controlling panel's which need extensive wiring 19. XBT N401XBT RT500 20. Introduction (What Is SCADA?) 1.Stands for supervisory control And data acquisition. 2.SCADA systems are used in industrial processes: steel making, power generation (conventional and nuclear) and distribution. 3.There Are 4 Components In the SCADA System. 21. SCADA Components Field Instrumentation. Sensors, devices to control.Remote Terminal Units. RTU Vs. PLCCommunications Network. Equipment needed to transfer data to and from different sitesCentral Monitoring Station Collecting information gathered by the remote stations to generate the necessary action 22. PLC Vs Computer Plc Designed for extreme industrial environments Can operation in high temperature and humidity High immunity to noise Integrated command interpreter (proprietary) No secondary memory available (in the PLC) Optimized for Single task ComputerDesigned mainly for data processing and calculation Optimized for speed Cant operate in extreme environments Can be programmed in different languages Lost of secondary memory available Multitasking capability 23. Why PLC ? The controller is designed in modular form, so that sub-assemblies could be removed easily for replacement or repair. The control system needs the capability to pass data collection to a central system. The system becomes reusable. The method used to program the controller is simple, so that it can be easily understood by plant personnel. 24. Advantages of PLCs: Less wiring. Wiring between devices and relay contacts are done in the PLC program. Easier and faster to make changes. Trouble shooting aids make programming easier and reduce downtime.Reliable components make these likely to operate for years before failure 25.
