what is the difference between PLC and microcontrollers?
102164
Hi.  A PLC is a special microcontroller designed for industrial use, that is for controlling machinery or processes.  Usually a PLC is programmed using Ladder diagrams and specialized control software.  A microcontroller is a microprocessor that can be used for any type of application, but there some for special applications, like a PLC.  Here's a link.  Hope this helps.

which IC are you referring to? in general microcontrollers run code written in either C or assembly language, so you have to write the program, then compile it. after that you have to program it into the micro. that is done in several ways. some have to be plugged into a device that does it, some can be done through a serial port, and some use a JTAG interface to do it.

Not necessarily just electrical. I have friends taking a robotics course which is a mechanical engineering course. I believe it is dealing with things like factory automation.

Flip flops are embedded in microchips and provide many varied logic functions. Check the Wiki reference in the link below, its pretty good and contains graphics.\n\nI've also added a couple of other reliable links.

With control engineering you would be interested in the other aspects of electrical engineering, like power systems and power electronics. this is because those are the things that you apply the control to. \n  An electrical control engineer is the one responsible for the functionality of the whole system including the motors/generators, the sensors and the switches ( in a simple system). Normaly a control engineer works in something called control pannel, from where he sends and recieves data and assures that the process is done correctly. He also fixes the errors and reduces them to the least system error possible. \n\n Telecommunication is envolved in the work of control regarding the recieving and sending of data.\n\n  I'm a control engineer and was in a point of my life wondering if I want control or telecommunication till I discovered out that a control engineer can always make a masters in telecommunication and be good in both, but it doesn't work the other way since you need a semi perfect knowledge of electrical engineering.... good luck with your choice...

A "simple" filling system would not need PLC control or a flow meter.\nA 555 ic timing chip, a few switching components on a small circuit board and an electric solenoid valve on the supply.\nIf the flow and volume isn't consistent with time, add a float attached to a micro switch or an optical sensor to override the time setting.

Microprocessor is a micro processor. \n\nIt processes data, performs calculations and  stores data in a memory. Everything that a computer does is overseen by the CPU and is therefore referred to as the "Brain".\n\nTwo good sites for more information is http://en.wikipedia.org/wiki/Microprocessor\nhttp://computer.howstuffworks.com/microprocessor.htm

It is a microprocessor based control system for machines and equipments used e.g. in factories, shop floor etc. For more details follow this Wikipedia link:\n\nhttp://en.wikipedia.org/wiki/Programmable_logic_controller

Laser Micrometers are used in a variety of industries and employed in a wide range of applications. Industries like Fiber Optics, Cable and Wire manufacturing, Plastic or Metal Tubing manufacturing, SMT component placement equipment or "Pick and Place" machines, Semiconductor, Biotechnology and many other industrial factory automation applications, that require FAST, RELIABLE and ACCURATE measurements of objects at the LEAST possible price.

The preamble can be 130 or 128 bits.  I believe it is the Physical Layer Convergence Protocol or PLCP preamble section, just before the 6 byte header.\n\nSome products are hard coded to 130, and others to 128 (like Samsumg I730).  When those meet, there is no way for them to connect.  Most newer ones will recognize the both preamble lengths.

To be honest, there isn't much difference between them.\n\nBoth are reputable, reliable companies. \n\nI use a combination of both here at work.\n\nHope this helps!

Verilog is a lot like C or Java, with some syntax differences. The real trick is learning how to apply the key areas of the language to a specific task, for example, synthesizable digital logic design or verification. Your best bet is always to learn by example, so that you can focus your energy on the subset of the language and syntax you'll need to get the job done.\n\nYou may be able to find resources on www.synopsys.com in terms of how to write synthesizable code. Also search the web and you'll find some freeware verilog simulators which will help you run your code. There are also some books available on amazon.com.

A control system is a device or set of devices that manage the behavior of other devices.A control system is an interconnection of components connected or related in such a manner as to command, direct, or regulate itself or another system.\n\nThere are two common types of controllers, with many variations and combinations: logic controls, and feedback or linear controls. There is also fuzzy logic, which attempts to combine the easy design of logic with the real-world utility of feedback controls.

Of course it depends upon the application in question. \n\nYou use a digital controller if you just want to be able to control something in an on off way.\nExamples\nThe numbers on a telephone - why would you ever want to only half press the number down?\nThe big red button that launches a missile - you can't "half" launch a missile.\n\nAnalogue control is used when you want gradation in the amount of controlling. So, the steering wheel of a car is an analogue controller because you're not going to have much control if you can only turn completely to the left or completely to the right.\n\nI'm guessing your after something more specific, which means you're gonna have to ask a more specific question!

I assume the difference is that an electro-pneumatic system is a pneumatic system that uses electrical components to control the pneumatics.\n\nDo a Yahoo search, you'll find out all the details.
