  • 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
