21029-2

21029-2 is an International Standard for Industrial Automation systems, developed by the International Electrotechnical Commission (IEC). The standard sets out the design process, data representation, communication protocols, and other essential components for the design and implementation of automation systems. It is used to ensure the interoperability of automation equipment and components from different vendors and manufacturers.

At the heart of the 21029-2 standard is the application field. Application fields are the building blocks for an automation system. Application fields are defined as areas of common operations that require automation to operate smoothly. Examples of application fields include motion control, process control, safety systems, robotic control, diagnostic systems, and environmental control. Each application field defines specific criteria that must be met in order for the system to operate properly.

The most important aspect of the 21029-2 standard is the working principle. All automation systems must adhere to the principle of object-oriented design, with all objects being represented in the system as individual objects. This means that each object must represent a defined set of operations, and must be accessible to other objects in the system. The working principle also includes communication protocols, such as CANbus, OPC UA, and Modbus, that must be followed in order for systems to communicate with each other.

The 21029-2 has many practical applications in the field of industrial automation. It enables the design and implementation of automation systems that are well suited to the purpose and environment in which they are used. It also reduces risk and ensures that operations are carried out safely and efficiently, while minimizing human intervention.

In conclusion, the 21029-2 is a comprehensive standard for industrial automation systems. It outlines the design process, data representation, communication protocols, and other essential components for the design and implementation of automation systems. Its application fields and working principle ensure the interoperability and safety of automation systems.
