Program Plan Intro

Programmable Logic Controller (PLC):

• Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process.
• PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
• The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
• When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
• The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language.

RSLogix software:

• Most of the PLCs programming packages operate on windows based operating system.
• RSLogix software is one of the best examples for windows based programming software.
• The main benefit of using this software is that it is available in different versions.
• It can also be used to develop and monitor ladder logic programs such as PLC-5, SLC 500, ControlLogix and MicroLogic family processors.
• Moreover, this software is also compatible to DOS based programming packages.

RSLinx software:

• RSLinx refers to a windows based communication software package.
• It was developed by Rockwell.
• It is used to download a program from PC to PLC, upload a program from PLC to PC, and to monitor PLC activity.
• In order to meet the demand for cost and functionally requirements, RSLinx software is available in multiple packages.
• It works almost similar to a printer driver for RSLogix software.
