Data manipulation instructions: Data manipulation instructions enable the numerical data that exists in the controller’s memory to be performed within the control program. Data manipulation instructions allows manipulation of data that is stored in either single or multiple words groups. It also includes the transfer of data from one data memory area of the Programmable Logic Controller (PLC) to another. In order to accomplish data manipulation, there are mainly two different kinds of instructions. Instructions which operate on word data. Instructions which operate on file or block. There are mainly two broad categories of data manipulation instructions as follows: Data transfer instructions Data comparison instructions MOV instruction: Move (MOV) instruction is used to copy the data of the source register into destination register. Here, the contents of the source register will not be altered. In other words, it is used to copy the value in one word or register to another word or register.
