What is the different between PLC and PIC?

Question

I know that PLC technology is used for example controlling the machines in a company, and I know a lot about it. But I don't have any information about PIC in general, so would you help me?

Answer 1

in my industry PLC is progamable logic control. which you say you know about.
PIC is Programmable Integrated Circuit.
PLC suggests that you have a machine (eg robot) with a control module. you enter commands that teh module interprets to control the range of motion of the machine.
A PIC is much more basic. it is just a chip. assuming you have a plan to put the chip in a device (eg robot) then your machine design specifies which pins have sensor input and which have motor control output (just for example). you write code on a PC and download it into the PIC. the code defines the functions of the individual pins of the chip, and based on what you have written determines the change in output based on change of input.

Answer 2

PIC is just a type of micro controller made by Arizona microchip, they make literally hundreds of types of pic's, PiC can be used for just about any project requiring a micro controller (robotics application, consumer electronics applications etc)

a PLC is really just an extension to a micro controller adding protected inputs and outputs to help prevent damage (static electricity, voltage spikes etc) to the micro controller and other features the would be needed in an industrial environment

A PLC may be built from a PIC, but I could also built from any other micro controller, amtel etc

Answer 3

PIC is a brand of integrated circuit microcontroller (a microprocessor with added input/output capability and built-in peripherals).

Technically you could make a whole PLC system with some of the larger PIC chips, but I have not seen that done in the industry.

Here is the main web-site for PIC chips:
