PLCs are somewhat similar to Microcontrollers…! i.e. user can write program using a computer and burn it in to the memory of microcontroller via a cable. Here CircuitsGallery providing you basic PLC training with PLC programming. You will be able to learn PLC automation, PLC controls and How to program PLC via our upcoming PLC programming courses in CG.
Difference between PLC and Microcontroller
- PLC is mainly used for industrial applications, PLCs allow end user to organize and control the application which is more helpful in industries. Very complex controls and process like chemical industries requires more re-configurable controls.
- Microcontroller design would be suitable where end user need not modify the controls eg: Automatic washing machine.
- PLC programming is a type of graphical programming called ladder diagrams which are simple to understand, extremely easy and customized.
- Microcontrollers are programmed using either Assembly language or C language. Compared to Ladder Diagram these are much complicated.
- Trouble shooting is easier in PLC than microcontroller via online programming (we can see the real time working of PLC through computer).
- PLCs are electrically based controllers but Microcontrollers are electronics based.
- PLC module is costly as comparing with microcontroller, thus PLCs are commonly used in industries where as microcontrollers are applied in simple applications due its low cost.

Advantages of PLC
PLC has made a considerable role to Industrial automation. Former automation scheme had to use thousands of individual relays, timers and counters, which had to be rewired whenever we need a modification in the automated process. PLC permits all of the relays and timers within an industry to be replaced by a single controller. Present PLCs provide wide range of operations, including basic relay control, process control, motion control, and complex networking. They also be able to be used in a distributed control system (DCS).
