PLC TRAINING : Introduction :

The Programmable Logic Controller was developed in 1968 by the Engineers of General Motors for replacing the complex relay logic control.

Working Principle :

PLC is a microprocessor based solid state device.PLC works on the principle of Logic Gates. The input device may be pushbutton or limit s/w, relay contacts or timers etc. which send signal to the control elements and the o/p device may be motors, solenoid, relay coil, etc.
Inputs is given in the input image memory, CPU process it according to logic written in the memory and update the o/p in o/p image memory. PLCs control the components in the DCS and SCADA systems but they are primary components in smaller control configurations.

Programme Scan

RLC Scane the programme parallel

PLC Scan the Programme sequencely in steps from top rung to bottom rung & scanning will be continue If PLC is in run mode & will be stop if PLC is in stop mode. One scan time is generally 10 to 20 ms.

The new control system developed with following:

1) Simple programming.
2) Program change (editing) without system intervation (no internal rewiring) in a software.

SCADA

Supervisory Control And Data Acquisition refers to a centralized system and this system is composed of various subsystems like Remote Telemetry Units, Human Machine Interface, Programmable Logic Controller or PLC and Communications.
SCADA system is composed of 3 main elements.


PLC Training in Delhi NCR (Programming Languages & Logic Gates) :

The switching unit at input and output operate according to certain logic. The inputs can have only two values viz. 0 or 1, the basic elements may be electrical s/w, and transistors, relays, which have two states viz. 0 or 1. The languages for logic design are through the use of Boolean algebra. The basic logic function are ‘AND’, ‘OR’ and ‘NOT’.

PLC Programming Languages:

1) LADDER
2) FBD
3) STL 1) LADDER:
It is a language which represents the graphical view of electrical circuit. It is the combination of more than one ‘RUNGS’.

RUNGS:

When a coil is connected with series or parallel combination of digital inputs (NO/NC Contacts) elements is known as one ‘RUNG’. Combination of rungs known as Ladder diagram.

Programming Logic Control (PLC training in delhi NCR) system consist of

  • • Inputs, Outputs
  • • CPU
  • • Power Supply
  • • Memory for program & data storage
  • • Power Supply
  • • Operator Interface
  • • Programming Device


KITC (Krishna Automation - Plc training in delhi ncr) is established to prepare young students/ aspirants for modern industrial need by their experience and knowledge. So that they can be productive from day one.
