Programmable Logic Controller (PLC): Programmable Logic Controller (PLC) is a specialized computer used in industrial segments to control machines and process. PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks. The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC. When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes. The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling programming language. Math instruction: Math instructions refer to all output instructions that uses the data of two words or registers and perform the desired function. Math instructions are program based on the type of processor used. The data manipulation instructions are almost similar to math instructions. The math instruction allows the PLC to take more of conventional computer qualities. Math instructions are normally used to perform arithmetic functions on the values stored in memory words or registers.
