Basic concepts and functions of industrial bus converters

An industrial bus converter is a device used to convert data between different industrial bus protocols. With the diversification and complexity of industrial automation, the demand for communication between different devices is increasing, and industrial bus converters play a vital role in this environment. This article will explore the basic concepts and functions of industrial bus converters.

Basic concepts of industrial bus converters

An industrial bus converter is a hardware device or software tool used to convert and exchange data between different communication protocols or bus systems. This device ensures that devices from different manufacturers and protocols can work together in the same network to achieve information interoperability and system integration.

Common protocols that industrial bus converters can handle include:

CAN (Controller Area Network)

Modbus (RTU and TCP)

PROFIBUS

Ethernet/IP

DeviceNet

RS-232/RS-485

Core functions

Protocol conversion

The main function of an industrial bus converter is to convert data from one protocol to another. This includes data format conversion, protocol stack parsing and repackaging to ensure that devices with different protocols can communicate seamlessly.

Data Routing

The converter is responsible for routing data packets between different networks or subnets to ensure that the data can reach the designated device. This function supports data exchange and control in complex network structures.

Signal Conditioning

During long-distance transmission, the signal may be attenuated or distorted. The converter provides signal amplification and conditioning functions to ensure the integrity and reliability of the data.

Isolation Protection

The converter provides electrical isolation to prevent voltage fluctuations or short circuits from affecting other devices, improving the safety and stability of the system.
