Programmable logic controller (PLC) is another name for an electronic computer. It is used mainly in industrial environments to control machines. The logic circuits take in instructions from a programmer and the logic circuits fulfill that programming function by using logic, sequencing, timing, and counting to process the commands entered in. PLCs are great for industries for the very purpose of being able to control machines for different purposes. Designing these controllers requires fabricating the boards in such a way to form a small chip with all the components, electronic path, wiring, and other chips required for the chip to perform its function. The best way to explain this is the assembler would take the most commonly available microprocessor, and standard as well as custom interface boards, to produce the desired product.

Industries like developing and using PLCs because they are so small they aren’t in the way. Being so small also allows for computational power to be available to the equipment or machine that will use it. This means placing it near or on the machine that will use the processor to perform its functions. Also, being so small they are also durable which is a blessing because they last for a long time. Another advantage is the fact everything is contained in one package, therefore less parts are used which means less installation and maintenance is required.
