PLC: A PLC, or programmable logic controller, is a rugged computer used in industrial automation. These controllers have the ability to automate a particular procedure, a machine feature, or even an entire manufacturing line. How does a PLC function? The PLC collects data from attached sensors or input devices, processes the information, and then initiates …
What is PLC? A PLC is a digitally operated device that would utilize programmable memory to store the instructions internally, by executing certain functions such as timing, counting, arithmetic, and logic sequencing. These functions are executed to control various kinds of machines or processes. So it can be used to control the equipment in an …
What is a PLC control system and how does it operate? The Programmable logic controller is a digitally operated device that has a programmable memory for storing the instructions and also to do, the specified functions. A PLC would do logic, arithmetic, timing, counting, and sequencing functions to control various machines in an industrial process. …
What is a logic gate? We can define a logic gate as a digital circuit and mostly it would have two inputs. The logic gates would have a logical relation between the input and output, major types of logic gates are AND, OR, XOR, and NOT. The inputs and output of the logic gates will …
