Program Plan Intro

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.

Need help answering these questions!1. Design a While loop that lets the user enter a number. The number should be multiplied by 10, and the result stored in a variable named product. The loop should iterate as long as the product contains a value less than 100.   2. Design a For loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 . . . 1000   3. Convert the While loop in the following code to a Do-While loop:     Declare Integer x = 1     While x > 0        Display "Enter a number."        Input x     End While
