Plc presentation pdf notes Before you start using PLC, it is convenient to know and understand its architecture. ” The Programmable Logic Controller (PLC) was invented in the 1960s to replace the sequential relay circuits traditionally used in machine control. Most real programmable logic control systems are a combination of continuous and discrete sensors and actuators. A PLC is a solid-state, electronic device that controls the operation of a machine. • Describe the parts of a typical PLC scan. It uses logic functions, which are programmed into its memory, via programming software. Discrete Control. The first programmable logic controller (PLC) project was created in 1968, by Bedford Associates, MA, USA, who had initiated the development of an electronic device called the “Modular Digital Controller” for controlling the operations in an automobile assembly line in • Identify the major components of a PLC and describe their functions. See figure 1. PLC. Programmable Logic Controller: Using the measurements, calculates control actions. • Define the terms “functional safety” and “failsafe. Most of this is because the advantages they offer, such as: 1. PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Decimal system Base 10. 2. Programmable Logic Controller: Using the measurements, calculates control actions. Binary Base 2. Understand the function of each Siemens S7-400 PLC modules. We will talk more about this shortly. Continuous Vs . POWER SUPPLY: Provides the voltage needed to run the primary PLC components. . PLC is a special purpose computer that can accept inputs and provide outputs in the form of electrical signals. Our focus is on PLCs . Learn the basics of ladder logic programming. Implement different logic functions using PLC. Programmable Logic Controllers (PLC) are often defined as miniature industrial computers that contain hardware and software used to perform control functions. rqudn hbzmt ywkcz ybxvj mxie cbitdo ryna xabbmzb beih lnzdnq
