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 programmed based on the type of processor used. The data manipulation instructions are almost similar to math instructions. 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. MOV instruction: Move (MOV) instruction is used to copy the data of the source register into destination register. Here, the contents of the source register will not be altered. In other words, it is used to copy the value in one word or register to another word or register. 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.

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.

MOV instruction:

Move (MOV) instruction is used to copy the data of the source register into destination register.

Here, the contents of the source register will not be altered.

In other words, it is used to copy the value in one word or register to another word or register.

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.
