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.
- It also provides great flexibility to program control circuits.
File:
- A file refers to a group of words contained in the data table.
- It must have a definite start and end positions.
- It is used for storing information.
