SG500 Energy Consumption Gateway

Industrial gateways play a crucial role in industrial internet connectivity and digital transformation, with one of their core functions being the conversion between various industrial protocols. This article will focus on common protocol conversion scenarios for industrial gateways and introduce the product features and customization capabilities of Yeaplink Technology’s SG500 energy consumption gateway as an example.

Typical Protocol Conversion Scenarios

First, let’s understand some typical scenarios where industrial gateways need to perform protocol conversion:

1. Conversion Between Industrial Ethernet Protocols

Industrial Ethernet is widely adopted in the industrial automation field, but different manufacturers and devices use various industrial Ethernet protocols, such as Profinet, EtherCAT, EtherNet/IP, Modbus TCP, etc. Industrial gateways need to seamlessly convert between these protocols to achieve device interconnection.

Conversion Between Industrial Buses and Industrial Ethernet

In addition to Ethernet, many industrial devices also use various fieldbuses, such as Profibus, CANopen, DeviceNet, Modbus RTU, etc. To integrate these devices into Ethernet-based systems, industrial gateways need to convert between industrial bus protocols and industrial Ethernet protocols.

Conversion Between Industrial Protocols and IoT Protocols

With the development of industrial IoT, more and more industrial devices need to upload data to the cloud for analysis and management. This requires industrial gateways to convert data collected from industrial protocols like OPC UA, Modbus, etc., to IoT protocols like MQTT, for integration into IoT platforms.

Conversion Between Different Industrial Wireless Protocols

In some wireless application scenarios, industrial devices may use wireless protocols like WirelessHART, ISA100.11a, etc. Industrial gateways need to convert and transmit data between these wireless protocols and wired networks.

Conversion Between Serial Ports and Networks

Many traditional industrial devices use RS232/RS485 serial communication. To integrate them into networks, industrial gateways need to convert between serial protocols like Modbus RTU and network protocols like Modbus TCP.
