Need help with a simple project

Sun, 22 Apr 2012 04:36:38 +0000

Looking for some advice for a project. I have a extreamly small busness and I have a machine that I would like to partially automate. What I am looking to do is control incoming flow to a pump with a valve. Currently the operator monitors a vacuum gauge and adjusts input manually. I would need to monitor vacuum, discharge pressure, and line speed. Is plc the way to go or what other options are there? Budget is a concern also I am looking for the most cost effective way possible. Thanks

New to industrial automation...please guide me...

Fri, 30 Mar 2012 10:32:57 +0000

Hello,

I'm quite new to this domain (PLC based automation), from the very first day I found a lot to learn here....But as time goes I get to know that the career prospect as well as pay packages (without big MNCs) are not appreciable.

Apart from this, I was a student of Electrical Engineering, If I stick to this domain, shall I be going away from my department ?

Does this job belong to Instrumentation or Electrical ?

What is DCS? How it differs from PLC? Does PAC system merge the qualities of both the system?

In future, if I want to work with various drives system...what should I do?

I would really be grateful if anybody guides me about the above said points.

Super 6 Dissertation Writing Tips That Will Guarantee an �F� Grade

Sat, 24 Mar 2012 10:46:56 +0000

If you think that getting an F in your final dissertation is not an easy task, then you are wrong.

All you need is a little carelessness in the formatting, composing and structuring of your research report and (Voila!) you will achieve an F easily.

Below mentioned are 6 dissertation writing tips that will help you along your way to failure.

1.Work on a research theme that has been done before:
If you are assuming that your work is original because you have not conducted proper research in the field to check past literature, then you are in serious trouble. All your efforts have been futile and your dissertation serves no significance in your chosen field. This will be quite hard to justify and defend in your dissertation defense.

2.Use blogs or online journals as your dissertation reference:
This is a new problem that is being seen in dissertations recently. To Google and use information without proper scrutiny is a surefire way to fail. Remember, blogs and online journals are inauthentic sources for information and are not suitable to be used in a research report.

3.Refer to the references in your dissertation as 'this academic' or 'all the literature':
The entire point of a research report is to compose one that is original and significant. Using other sources and then not properly acknowledging then can easily lead to an F. Remember; plagiarism is inexcusable in research reports. This also means that generalizations should be strictly avoided. Categorizing the masses with "all the academics" is a guaranteed turn-off for your research reviewers.

4.Don't compose a proper introduction or conclusion:
The introduction and the conclusion are two of the most important components in a dissertation. If either of these parts are poorly composed or does not accumulate to the proper word count can give a bad impression on your entire thesis. Composing a poor introduction means that you have not done enough research for the dissertation and a poor conclusion signifies that you have nothing substantial to add to the research field which can be quite disappointing for the reviewers after the hard work that has gone in your investigative report.

5.Submit a poorly formatted research report with spelling and grammatical mistakes:
If you think that your reviewers won't be judging the book by its cover, then you are sadly mistaking. Your investigative process may be excellent but if you are writing a dissertation that is not properly composed and free of grammatical and spelling mistakes, then you can never pass. A final year thesis student is expected to have a strong command over report writing. Try not to disrupt that illusion.

6.Work on a large scoped thesis topic:
Time is a restriction for students. The research process must be completed in the designated period. Many students have the error of selecting themes that are too large to be completed in the chosen time which results in a haphazardly completed report which clearly demonstrates a poor theme choice.

In conclusion, if you are set on failing your dissertation then follow the above mentioned tips to help you fasten the process.

Major Types of Industrial Control Systems

Tue, 24 Jan 2012 10:14:46 +0000

Major Types of Industrial Control Systems
Industrial control system or ICS comprise of different types of control systems that are currently in operation in various industries. These control systems include PLC, SCADA and DCS and various others:

PLC
They are based on the Boolean logic operations whereas some models use timers and some have continuous control. These devices are computer based and are used to control various process and equipments within a facility. PLCs control the components in the DCS and SCADA systems but they are primary components in smaller control configurations.

DCS
Distributed Control Systems consists of decentralized elements and all the processes are controlled by these elements. Human interaction is minimized so the labor costs and injuries can be reduced.

Embedded Control
In this control system, small components are attached to the industrial computer system with the help of a network and control is exercised.

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.

what is difference between SCADA vs DCS

Fri, 20 Jan 2012 07:03:37 +0000

The goals of DCS and SCADA are quite different. It is possible for a single system to be capable of performing both DCS and SCADA functions, but few have been designed with this in mind, and therefore they usually fall short somewhere. It has become common for DCS vendors to think they can do SCADA because the system specifications seem so similar, but a few requirements paragraphs about data availability and update processing separates a viable SCADA system from one that would work OK if it weren't for the real world getting in the way.

DCS is process oriented: it looks at the controlled process (the chemical plant or whatever) as the centre of the universe, and it presents data to operators as part of its job. SCADA is data-gathering oriented: the control centre and operators are the centre of its universe. The remote equipment is merely there to collect the data--though it may also do some very complex process control!

A DCS operator station is normally intimately connected with its I/O (through local wiring, FieldBus, networks, etc.). When the DCS operator wants to see information he usually makes a request directly to the field I/O and gets a response. Field events can directly interrupt the system and advise the operator.

SCADA must operate reasonably when field communications have failed. The 'quality' of the data shown to the operator is an important facet of SCADA system operation. SCADA systems often provide special 'event' processing mechanisms to handle conditions that occur between data acquisition periods.

There are many other differences, but they tend to involve a lot of detail. The underlying points are:

SCADA needs to get secure data and control over a potentially slow, unreliable communications medium, and needs to maintain a database of 'last known good values' for prompt operator display. It frequently needs to do event processing and data quality validation. Redundancy is usually handled in a distributed manner.

DCS is always connected to its data source, so it does not need to maintain a database of 'current values'. Redundancy is usually handled by parallel equipment, not by diffusion of information around a distributed database.

These underlying differences prompt a series of design decisions that require a great deal more complexity in a SCADA system database and data-gathering system than is usually found in DCS. DCS systems typically have correspondingly more complexity in their process-control functionality.

The company I work for has both DCS and SCADA products. The operator stations for each product line can use the same UNIX workstations. The systems share data (and thus form a composite SCADA/DCS system), but the SCADA database architecture is significantly different from the DCS data architecture, to the extent that the SCADA master station database looks to the DCS operators very much like some directly-connected DCS I/O. The DCS people are (of course) keen to simplify this to cut costs. However, they do not yet have a viable alternative for the mechanisms required in SCADA systems to have communications redundancy and data redundancy to provide the sort of SCADA system reliability that our customers expect.

Some typical applications in an industrial environment system?

Thu, 19 Jan 2012 11:48:35 +0000

The most common application is for individual machine control but can range to full plant control linking several PLCs together. On a particular machine, speed, options, Safety, operator interface, pneumatic, hydraulic, electricity are some items that may be controlled. PLCs have several different types of input and output cards depending on the type out interface desired. All machines, room temperatures, power monitoring, even security can be joined by linking several PLCs. These can then be displayed and controlled by a single Graphical User Interface (GUI) o a standard Personal Computer.
