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. MVM instruction: Masked Move (MVM) instruction refers to a word instruction. It is used to move data from source to destination and allows a portion of destination data to be masked by a separate word. The function of MVM instruction is almost similar to that of MOV instruction, except that a masked move allows the data to be filtered out which is not required to be moved.

Scenario You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement. You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds. The conversions are as follows: 1 kilogram = 35.274 ounces 1 kilogram = 2.20462 pounds 1 pound = 0.453592 kilograms 1 pound = 16 ounces 1 ounce = 0.0283 kilograms 1 ounce = 0.0625 pounds For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you…
