About Basic PLC Training in Coimbatore

Basic PLC TrainingA programmable logic controller, PLC, or programmable controller is a digital computer used for automation of typically industrial electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many machines, in many industries.

PLCĀ  includes Programmable Relays combine timers, relays, counters, special functions, inputs and outputs into one compact device that is easily programmed. They provide an exceptional level of flexibility together with substantial savings of commissioning time and effort.

What Is Inside A PLC?

The Central Processing Unit, the CPU, contains an internal program that tells the PLC how to perform the following functions:

Basic PLC Training Coimbatore

  • Execute the Control Instructions contained in the User’s Programs. This program is stored in “nonvolatile” memory, meaning that the program will not be lost if power is removed
  • Communicate with other devices, which can include I/O Devices, Programming Devices, Networks, and even other PLCs.
  • Perform Housekeeping activities such as Communications, Internal Diagnostics, etc.

How Does A PLC Operate?

There are four basic steps in the operation of all PLCs; Input Scan, Program Scan, Output Scan, and Housekeeping. These steps continually take place in a repeating loop.

  • Input scan: Detects the state of all Input devices that are connected to the PLC.
  • Program scan: Executes the user created program logic.
  • Output scan: Energizes or de-energizes all output devices that are connected to the PLC.
