Chapter 10, Problem 13RQ
Program Plan Intro
Data comparison instructions:
- Data comparison instructions refer to input instructions.
- It is used to compare two numerical data values and take decisions based on the program instructions.
- It can also be used to check the numerical value pairs for determining if a rung is true.
- The basic set of data comparison functions performed by PLCs are as follows:
- Equal to (=)
- Not equal to (!=)
- Less than (<)
- Greater than (>)
- Less than or equal to(<=)
- Greater than or equal to (>=)
- The above given compare instructions are used to compare the values of source A and source B.
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.
Explanation of Solution
b.
LESS THAN instruction:
- The LESS THAN (LES) instruction is used to test whether the given value is less than the other value or not.
- If the given value such as Source A is less than Source B, then the instruction is logically true. Otherwise, the given instruction is logically false.
Explanation:
In the given logic rung,
- The output D is energized whenever input C is true...
Explanation of Solution
c.
GREATER THAN OR EQUAL instruction:
- The GREATER THAN OR EQUAL (GEQ) instruction is used to test whether the given value is greater than or equal to the other value or not.
- If the given value such as Source A is greater than or equal to Source B, then the instruction is logically true. Otherwise, the given instruction is logically false.
Explanation:
In the given logic rung,
- The output F is energized whenever input E is true...

Develop a logic circuit necessary to meet the following requirements:
In a certain chemical-processing plant, a liquid chemical is used in a manufacturing process. The chemical is stored in three different tanks. A level sensor in each tanks produces a HIGH voltage when the level of chemical in the tank drops below a specified point.
Design a circuit that monitors the chemical level in each tank and indicates when the level in any two of the tanks drops below the specified point.
The design must include a chip with logic gates and also be written with VHDL code.
Consider the ASM CHART. Design only the control logic of the system. Answer the following:
Design the control with multiplexers, a register, and a decoder.
Q ( 5
Find a ready-made combined logic circuit description or write it yourself directly. The module should have at least 4 ports, and at least one port should be 8-bit. Then verify with UVM using this module as DUT (Design Under Test).SystemVerilog hardware description language should be used.
