Hands on Training on

PLCs and VIFor Industrial Interlocks Control and Protection

Programmable Logic Controllers (PLC) are the devices which are now widely used in all types of process

industries for automatic control of operation on a real time basis. These devices can handle complex

operational functions of mechanical electrical devices in, say, machining, packaging, materials handling

or other automated industrial operations. In first part of this program the student gain knowledge about

PLC hardware and programming methods and use them for simple industrial applications.

Virtual Instrumentation (VI) is a suite of graphical system design tools, that has advanced control, high-

speed measurements, precision motion, machine vision, and human machine interfaces (HMIs) . The

core of VI is a graphical programming environment which can develop sophisticated measurement, test,

and control systems using intuitive graphical icons and wires that resemble a flowchart. In the second

part of the program the students get to learn basic features and use an open and flexible graphical

development environment that combines the ease of use of configuration-based tools with the

flexibility of a powerful programming language.

This is a 48 hour program divided into 16 sessions

of 3 hours which uses a multi-pronged approach

involving interactive classes, simulation software

and self-stud assi nments . At the be innin of Kenergizeddueto

program, the student will have an initial reading

assignment (which will be delivered in electronic

format in advance of the presentations). The

student practice on PLC and VI programming on

real life industrial interlocks control andprotection systems by means of simulation

software made available at the training centre.

There will be coursework or problems to be

submitted and student will also take up practical

exercises using these simulation software . They

prepare and upload short presentations on

specific areas of the program; this would be

treated as a task for assessment and feedback.

Better presentations would be used for sharing of

knowledge amongst participants. The participant

will have continuous ongoing support from thetrainers directly or through e-mail.

Outline of Program

The broad aims of this training program are:

Acquire knowledge on PLC hardware, programming and interfacing

Appreciate dimensions of PLC usage in industrial control, interlock and protection

Develop competency in simple PLC programming for interlock, control and protection using ladder logics

Develop an understanding of graphical system design tools (VI) for industrial application

This training is designed to benefit participants with information and hands on practice on the application of PLCs

and VI to the interlock, control and protection of plants and factories. It is suitable for people who have little or

no exposure to PLCs and VI, but expect to become involved in some or all aspects of these at a later stage. It aims

to give practical advice from experts in the field, by means of simple but practical examples to achieve a shorter

learning curve and more confidence.

While the training program is ideal for electrical, electronics and instrumentation engineering persons , those in

computer engineering or others relevant fields and new to PLCs and VI, much of the workshop and additional e-

material will be of great value to enhance knowledge and acquire skills to take up larger and more challenging

tasks ahead.

The Training

Practical Sessions

The practical sessions conducted in this training program progresses from the basics to advanced level which

challenge even the experienced engineer in the industry today. The trainees will undertake a series of practical

hands-on sessions, of relevance to industry, based on the simulated PLC and VI supplied during training. Full

working solutions for all problems will be distributed to participants after tehy have attempted the practical.
