Passerelle industrielle 2 ports RS485 vers Ethernet | Serveur série

2CH-RS485-ETH (V) is an RS485 edge computing IoT gateway specifically designed for industrial environments. It delivers deep system integration by combining a serial server, Modbus gateway, MQTT gateway, and RS485 to JSON converter. It has 2 Channels RS485 interfaces and an Ethernet interface, with optocoupler isolation, isolation voltage 1500V.

Supplied with mounting ears and rail buckles, it accommodates 3 installation methods for control cabinets. The network architecture supports advanced IP management: devices can use the same IP address, and different serial ports are distinguished by ports; alternatively, each serial port can use different IP addresses. It can not only save IP resources through shared addresses, but also enable independent network communication through different IP address.

The devices supports bi-directional transparent transmission and Modbus RTU to Modbus TCP function, has advanced storage Modbus gateway characteristics, and also supports MQTT protocol. Furthermore, it parses MODBUS RTU and 645 protocol conversion to JSON, facilitating scheduled telemetry upload function through MQTT/HTTP POST to enterprise platforms.

When used as a Modbus gateway, it supports Modbus TCP to Modbus RTU, so that central SCADA or the host computer can use the Modbus TCP protocol to collect data from RS485 Modbus RTU devices. On the contrary, if the RS485 end is used as a master station, it can also be used. It supports more advanced Modbus gateway functions, including configurable Modus gateways, storage-type Modbus gateways, etc., which fully meet various configurations and usages of Modbus gateways. The multi-host function it supports allows multiple computer master stations to access an RS485 slave device at the same time.

When used as an MQTT edge computing gateway, the device can transparently upload serial port data to the MQTT server using the MQTT protocol. Supported cloud servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet platform, etc. It supports parsing the collected Modbus RTU or non-standard serial port data into JSON format and encapsulating it in an MQTT data packet for secure telemetry uploading.

Supports uploading collected data in JSON format, automatic data collection, and supports Modbus RTU, 645 instrument version 97, 645 instrument version 07, and various non-standard RS485 protocols. Users can use Vircom to configure the uploaded data format and JSON keywords. When uploading, it can support MQTT protocol, HTTP POST protocol, HTTP GET protocol, transparent transmission protocol, and various non-standard network protocols.
