61812-1, also known as the IEC 61812-1, is an international standard issued by the International Electrotechnical Commission (IEC) that specifies the technical requirements of fieldbus systems used in industrial automation. The goal of the standard is to define the common features and services of the fieldbus system used in order to ensure interoperability amongst different manufacturers, devices and networks. The standard is based on the Common Industrial Protocol (CIP) and defines the network architecture, communication protocol, profiles, and related services.

The 61812-1 is used in a wide range of industries, including process and manufacturing, automotive, energy, and medical. It is used to provide power, control, and information for distributed networks, and is designed to meet the needs of applications requiring fast response times, high dependability, and scalability. The 61812-1 specification defines the communication architectures and protocol services for the fieldbus system, making it easier for the user to integrate different devices from different manufacturers.

The typical application for the 61812-1 is to provide the backbone for an industrial automation system. The fieldbus system is responsible for the flow of data between connected devices, such as sensors, actuators, controllers, and other field devices. The 61812-1 provides a uniform interface for these devices, making it possible to easily connect them to each other. The standard enables the connected devices to communicate with each other without requiring dedicated hardware or software.

In terms of its working principle, the 61812-1 fieldbus system consists of a network layer and a service layer. The network layer is responsible for the physical communication between devices, while the service layer is responsible for the control and data transport. The communication protocol of the 61812-1 is based on the Common Industrial Protocol (CIP). This protocol is designed to provide reliable and secure communication between the connected devices.

The 61812-1 fieldbus system provides a wide range of features and capabilities. It is capable of supporting both synchronous and asynchronous communication, as well as being scalable and secure. It also provides support for segmented or fully meshed networks, which can be used to support large or complex industrial automation systems. Additionally, it can be configured easily and flexibly, allowing it to be used in a wide range of applications.

Overall, the 61812-1 fieldbus system is a powerful tool for industrial automation. It is capable of providing reliable, secure, and fast communication between connected devices. Furthermore, thanks to its wide range of features and capabilities, it can be tailored to meet the specific needs of many different applications and industries. It is no wonder, then, that the 61812-1 is so widely used today.
