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 Programmable Logic Controller (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. Clear instruction: The clear instruction is used to set or reset all the bits of the word in the destination to zero. It is denoted as CLR. Destination: Destination refers to the address where the results of the instruction are stored. For example, if 1+1=2; then the value 2 is automatically stored in the destination address location.
