- A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on.ince the late 1960's, the Programmable Logic Controller (or PLC) has become an essential aspect of any automated manufacturing process. In recent times there have been contenders to replace the PLC but the priniciples and popularity of those early PLC's functions and concepts have continued unabated.

"What does the word ""PLC"" stand for in the lighting industry ?" YES the above definition is correct. Just like you can program a PLC easily to have timers and to turn on outputs based on time and switch inputs you can connect lamps to the outputs and make them do whatever you want (including a pulse-width modulation to dim or brighten the lights at any rate you want).

PLC SCADA A PLC is primarily used to control machinery. Programs written for PLCs consists in simple terms on instructions to turn on and off outputs based on input conditions and the internal program. In this aspect, it is similar to a computer. Programmable Logic Controller, or PLC, is more or less a small computer with a built-in operating system (OS). This OS is highly specialized to handle incoming events in real time, i.e., at the time of their occurrence.

Introduction to Programmable Controllers A Programmable Logic Controller, or PLC for short, is simply a special computer device used for industrial control systems. They are used in many industries such as oil refineries, manufacturing lines, conveyor systems and so on.n these modern times a PC with specially dedicated software from the PLC manufacturer is used to program a PLC. The most widely used form of programming is called ladder logic. Ladder logic uses symbols, instead of words, to emulate the real world relay logic control, which is a relic from the PLC's history.

Maintenance Management of your company's PLC What is a PLC? First I’d like to explain in the most non-technical terms possible, What a PLC is. As this article is not just for the maintenance technician, but for maintenance managers, plant managers and corporate managers. A PLC (Programmable Logic Controller) is the type of computer that controls most machines today. The PLC is used to control AND to troubleshoot the machine. The PLC is the brain of the machine.

About PLCs We have seen other instances in which educators assume that a PLC is a meeting—an occasional event when they meet with colleagues to complete a task. It is not uncommon for us to hear, “My PLC meets Wednesdays from 9:00 a.m. to 10:00 a.m.” This perception of a PLC is wrong on two counts.

Programmable logic controller Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. A PLC is an example of a hard real-time system since output results must be produced in response to input conditions within a limited time, otherwise unintended operation will result.LC applications are typically highly customized systems, so the cost of a packaged PLC is low compared to the cost of a specific custom-built controller design. On the other hand, in the case of mass-produced goods, customized control systems are economical.

THE INDUSTRIAL WIKI INPUTS AND OUTPUTS. Inputs to, and outputs from, a PLC are necessary to monitor and control a process. Both inputs and outputs can be categorized into two basic types: logical or continuous.Consider the example of a light bulb. If it can only be turned on or off, it is logical control.e can also use relay outputs to switch the outputs. The example shown in Figure 2.5 An Example of a 24Vdc Output Card (Sinking) and Figure 2.6 An Example of a 24Vdc Output Card With a Voltage Input (Sourcing) is repeated yet again in Figure 2.7 An Example of a Relay Output Card for relay output.

Examples of PLC Programming The following are some of the commonly used languages used to program a PLC: 1  Ladder Diagram (LD): The traditional ladder logic is a graphical programming language. 2  Statement List (STL): A high level text language that uses structured programming. PLC is similar to a computer as it has a central processing unit and generates outputs on the basis of some inputs.

Engineering Essentials: What Is a Programmable Logic Controller? A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is an Allen-Bradley PLC rack, a common example of a PLC setup that includes a CPU, analog inputs, analog outputs, and dc outputs. PLCs were introduced in the late 1960s by inventor Richard Morley to provide the same functions as relay logic systems.

What you need to know about PLC Outputs PLC Outputs are the control circuits of the PLC and also refers to the devices controlled by the PLC. Be aware when talking about PLCs the devices like motors and lights are also referred to as PLC Outputs.evices called actuators convert the electrical signal of the PLC to a physical movement for instance a valve solenoid stoke or a motor contactor. With regards to the variable output, the I/P (current to pneumatic) actuator, is an example.
