what is the difference between PLC & microcontrollers?

They are completely different as it was explained above. But other important difference is that a PLC could accept Analog Signals, Microcontroller is digital.

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.

An embedded system is a special-purpose computer system, which is completely encapsulated by the device it controls. An embedded system has specific requirements and performs pre-defined tasks, unlike a general-purpose personal computer. An embedded system is a computer-controlled system. The core of any embedded system is a microprocessor, programmed to perform a few tasks (often just one task). This is to be compared to other computer systems with general purpose hardware and externally loaded software. Embedded systems are often designed for mass production.

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.

Micro Electro Mechanical Systems\n\nIt is very hard to build as u should knw communications very well

P.C. controllers are your Motherboards chipset drivers - go to the MOBO's web site

try it... then you might want to go into details like integrated circuits ICs and transistors...\n\nhttp://en.wikipedia.org/wiki/Microprocessor

for what? there are so many microprocessors that your question cant be answered. be more specific in your question.

You didn't say what plc, servo, etc. but generally you get a servo control card for your PLC (sometimes called "axis module"), a servo amplifier, and a servo motor.\n\nYou place a desired position and some other parameters such as acceleration,deceleration in to registers in the PLC. The PLC card will then output a plus or minus 10 volt signal to the amplifier to move the motor. -10 volts is full speed reverse and +10 volts is full speed forward. +1 volt would be slow forward.  An encoder in the motor feeds back its position to the the servo card.\n\nThat's only one way. Several companies make stand-alone servo systems (intelligentactuator.com is one) that you either "teach" it a position or command a position and it does the rest.\n\nDepending on what you are doing, you project could be anywhere form easy to maddening.

PLC's is one example.

it really depends on what you are going to do with the micro. if its fairly basic stuff, then you can use 8 bit micro's, otherwise you need to use much faster and powerful ones like the powerQuicc.\n\nI have only dealt with the intel based 8 bit micro's, and in that type there are several manufacturers like atmel, philips, cygnal, etc.. Keil makes a pretty good C compiler for them too.

The answer to your question depends greatly upon the brand and model of PLC that you wish to learn to program. If the PLC in question is a currently-supported product, then find the manufacturer's website, and look for links to customer training. There is a standard for PLC programming, IEC 1131, but different brands can still be quite different. If you don't already have a good understanding of relay logic, then you should brush up on those skills before trying to learn PLC programming, as "ladder logic" is based on relay logic. Some PLC's are also programmed in Statement List logic and/or Flow Chart logic. Some programs may also use different languages in different sections of the program. You should get some good troubleshooting experience in your PLC programming class. Some manufacturers also offer "starter kits" at good prices for the go-getter who wants to learn on their own. A starter kit generally includes a small PLC, interface cable, and software.

Everythiny you want to control with a computer needs an interface -you can build all the progtams you want, if they aren't actually controlling a switch/switch gear/ motors/sensors etc etc then the computer (program) is just a useles box of instructions \n\n- Interfaces COST money unless you are MacGyver ;)
