The Power line carrier Communication (PLCC) uses the existing power infrastructure for the transmission of data from sending to receiving end. It works in full duplex mode. PLCC system consists of three parts: ... The 50/60 Hz power transmission line serves as path for relaying data in the PLCC bandwidth.

A programmable logic controller (PLC) is a type of computer commonly used in motor control applications. The traditional motor control circuit is hard-wired while PLC control is program-based. ... An electronic VFD, on the other hand, allows precise control of motor output.

They are used in many industries to monitor and control production processes and building systems. Once programmed, the PLC will perform a sequence of events triggered by stimuli referred to as inputs. It receives these stimuli through delayed actions such as counted occurrences or time delays.

The PID algorithm controls the output to the control point so that a setpoint is achieved. The setpoint may be entered as a static variable or as a dynamic variable that is calculated from a mathematical operation. economical HMI systems were developed for the PLC, PLCs became more accepted as PID controllers.

Production Controller or Manager. Production controllers or managers are in charge of the staff and activities involved in the production of goods in a factory. They ensure production lines run smoothly and efficiently.
284029
A Human Machine Interface (HMI) is exactly what the name implies; a graphical interface that allows humans and machines to interact. ... For a manufacturing line to be integrated with an HMI, it must first be working with a Programmable Logic Controller (PLC).

In the scope of industrialization, automation is a step beyond mechanization. Mechatronics is considered to be equal parts mechanical engineering, electrical engineering, and software programming/engineering. ... Industrial automation also consists of industrial robots, material handling processes and plc automation.
1028625
The PLC focuses on the project management phases, processes, tools and techniques for effectively managing the project. ... The SDLC focuses on the software engineering phases, processes, tools and techniques for building and/or implementing the IT solution.

The clue really comes from the name PLC, or “programmable logic controller”. It is the fact that they are programmable that makes them so versatile in their application. PLCs contain a processor, memory to hold their programming and other data and input and output modules. ... A PID Controller is different to a PLC.
1256560
A distributed control system (DCS) is a computerised control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control.

PLCs still are used to control individual machines, while a DCS can control a larger number of machines or processes within a factory or plant. One hallmark of PLCs is their relatively simple operating system, designed to do a minimum of tasks like scanning inputs and updating outputs.

abbreviation. PLC is an abbreviation of public limited company, a British business term. An example of PLC is a company in the UK with shares available to the general public.
1261857
PLC validation is a legal requirement in some industries such as drug manufacture, where product quality is particularly important. ... This documentation provides users with a high degree of confidence that a PLC will consistently provide control information or data that meets predetermined specifications.
