Industrial Automation Monitoring

This article examines the role of industrial automation, industrial monitoring, industrial control systems, PLCs, and industrial sensors in improving productivity, enhancing quality, and achieving precise control over production processes.

Today, industrial automation and industrial monitoring are recognized as two main pillars of modern industries. Industrial control systems, industrial sensors, and Programmable Logic Controllers (PLCs) form a set of technologies aimed at increasing productivity, reducing human error, improving production quality, and enabling real-time supervision of industrial processes. In this article, the basic concepts of industrial automation and monitoring, along with their role in developing advanced control systems, are explored.

Industrial Automation

Definition of Industrial Automation Industrial automation refers to the automatic control and guidance of a device or process. In these systems, decision-making for performing tasks is carried out by smart equipment, computers, robots, and electric machines instead of humans. Industrial automation becomes crucial when:

• Tasks must be performed repeatedly

• Precise and continuous supervision is required

• The work is dangerous or high-stress

• Speed and accuracy beyond human capability are needed

Therefore, industrial automation is one of the most important tools for the development of modern industries.

Applications of Industrial Automation Industrial automation is used in many industries, including:

• Oil, gas, and petrochemicals

• Chemical industries

• Food industries

• Automotive manufacturing

• Energy production

• Continuous production lines

Advancements in measuring parameters such as pressure, temperature, and flow have led to increased product quality and reduced production costs.

Benefits of Industrial Automation Industrial automation offers extensive benefits:

• High repeatability

• Increased product quality

• Higher production speed

• More precise quality control

• Reduced waste

• Increased productivity

• Reduced physical and mental stress on employees

• Enhanced workplace safety

For these reasons, industrial managers are moving towards using automatic machinery and advanced control systems to increase both the quality and quantity of production.

The Role of PLCs in Industrial Control Systems

Why is PLC Important? Automatic machines require a smart control unit to function correctly. This responsibility usually falls on the PLC. A PLC is a programmable controller that operates according to the machine’s programmed algorithm and can issue commands to actuators based on real-time conditions.

Advantages of PLCs over Older Systems In the past, relays, timers, and pneumatic systems were used for control. However, these systems were:

• Large in size

• Costly

• Non-expandable

• Difficult to repair

For these reasons, PLCs replaced them starting from the 1980s.

Advantages of PLCs:

• Low installation and commissioning costs

• High installation speed

• Compact size

• Easy maintenance

• Expandability

• Ability to perform complex operations

• High reliability factor

• Modular structure

• Noise resistance

• Ability to change programs while running

• Networkability between multiple PLCs

• Remote control capability

• Support for standard peripheral equipment

Today, the PLC is one of the most important components of industrial control systems.

Industrial Sensors; The Eyes and Ears of Automation

The Role of Sensors in Industrial Automation In any industrial process, the first step of the control cycle is data acquisition. This is done by industrial sensors. Sensors measure the actual state of the process and send the data to the control system.

Without sensors, there is no automation. Sensors are so critical in industrial machinery that the number of sensors often indicates the level of automation of a system.

Industrial Monitoring

Definition of Industrial Monitoring Industrial monitoring refers to the collection, display, and analysis of information from various sections of an industrial unit. Large industries such as petrochemicals, energy production, and chemical industries cannot operate safely and economically without industrial monitoring.

Goals of Industrial Monitoring Industrial monitoring is used to achieve the following objectives:

• Display real-time equipment status

• Record critical system parameters

• Display and record alarms

• Display the location and time of failures

• Graphical display of the production process

• Ability to change Set Points

• Ability to modify certain control processes

• Recording managerial information such as:

  • Operating time

  • Production volume

  • Raw material consumption

  • Energy consumption

Industrial monitoring is one of the main foundations of modern control systems.

Types of Automation Systems Due to the wide variety, only the names of the systems are listed here:

• Manual

• Pneumatic

• Electronic

• Direct Digital Control (DDC)

• Digital Communication + Networking

• Distributed Control System (DCS)

• Fieldbus Control System

• Hybrid Control System

Conclusion Industrial automation, industrial monitoring, industrial control systems, PLCs, and industrial sensors form a set of key technologies that increase productivity, reduce costs, and enhance production quality. In modern industries, the use of these systems is not a choice, but a necessity.
