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.

Chapter 11, Problem 5P

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 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.

I would like to get help to resolve the following case

Last Chance Securities The IT director opened the department staff meeting today by saying, "I've got some good news and some bad news. The good news is that management approved the payroll system project this morning. The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid possible fines and penalties for noncompliance. The bad news is that the system must be installed by January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in advance, the system should have a modular design if possible, and the vice president of finance would like to announce the new system in a year-end report if it is ready by mid-December."

2. Signed Integers Unsigned binary numbers work for natural numbers, but many calculations use negative numbers as well. To deal with this, a number of different methods have been used to represent signed numbers, but we will focus on two's complement, as it is the standard solution for representing signed integers. 2.1 Two's complement • Most significant bit has a negative value, all others are positive. So, the value of an n-digit -2 two's complement number can be written as: Σ2 2¹ di 2n-1 dn • Otherwise exactly the same as unsigned integers. i=0 - • A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1, or 1 becomes 0) and then add 1 to the least significant bit. • Addition is exactly the same as with an unsigned number. 2.2 Exercises For questions 1-3, answer each one for the case of a two's complement number and an unsigned number, indicating if it cannot be answered with a specific representation. 1.
