Editor to share with you what are the basic elements of the fieldbus protocol, I believe most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

The three basic elements of fieldbus protocol are the bottom protocol, the upper protocol and the protocol model. Fieldbus is a kind of industrial data bus, which can save maintenance overhead, improve the reliability of the system, and provide users with more flexible system integration initiative.

Introduction:

The three basic elements of fieldbus protocol are the bottom protocol, the upper protocol and the protocol model. Fieldbus is a kind of industrial data bus, which can save maintenance overhead, improve the reliability of the system, and provide users with more flexible system integration initiative.

Detailed introduction:

Field bus (Field bus) is a kind of industrial data bus developed rapidly in recent years. It mainly solves the digital communication between intelligent instruments, controllers, actuators and other field devices in the industrial field, as well as the information transmission between these field control devices and advanced control systems. Because of a series of outstanding advantages, such as simple, reliable, economical and practical, fieldbus has been highly valued by many standard groups and computer manufacturers.

Bus features:

The field control equipment has the communication function, which is convenient to form the bottom control network of the factory.

The openness and consistency of communication standards make the system open and interoperable between devices.

The standardization of function block and structure makes the devices with the same function interchangeable.

The control function is devolved to the field, so that the structure of the control system is highly decentralized.

Bus advantages:

Fieldbus makes automatic control equipment and system step into the ranks of information network, and opens up a broader field for its application.

Multiple control devices can be attached to a pair of twisted pair to save installation costs.

Save maintenance expenses

The reliability of the system is improved.

It provides users with more flexible initiative in system integration.

Bus disadvantages:

In network communication, the transmission delay of data packets, the instantaneous error and packet loss of the communication system, and the inconsistency between transmission and arrival order will destroy the original certainty of the traditional control system and make the analysis and synthesis of the control system more complex. the performance of the control system is adversely affected.
