Chapter 11, Problem 8RQ
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 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.
Math functions:
The basic math functions performed by PLCs are as follows:
- Addition
- This function is used to add one piece of data to another.
- It is also called as ADD.
- Subtraction
- This function is used to subtract one piece of data from another.
- It is also called as SUB.
- Multiplication
- This function is used to multiply one piece of data by another.
- It is also called as MUL.
- Division
- This function is used to divide one piece of data from another.
- It is also called as DIV.
Terms used:
The following terms are used in the instruction.
- Source A
- Source A refers to the address of the first piece of data that is used in the instruction.
- Source B:
- Source B refers to the address of the second piece of data that is used in the instruction.
- Destination
- Destination refers to the address where the results of the instruction are stored.
