Functions Introduction
Basic Function
It can make RS485 to Ethernet bidirectional transparent transmission function come true.
Various Modes of Communication with Host Computer
As TCP Server
Supports 30 TCP client connetions
As a TCP Client
Connects to 7 TCP Servers at the same time
As UDP Server
As UDP Client
PS: It can identify the data which are sent by different network devices, and make corresponding responses to prevent data dislocation. It can also effectively solve the problem that serial port device replies to the wrong position after multiple network devices sending data at the same time.
MQTT/JSON Convert to Modbus
When used as an MQTT gateway, the device can upload serial data to an MQTT server using the MQTT protocol through transparent transmission. The supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet platform, etc. It also supports parsing the collected Modbus RTU or non-standard serial port data into JSON format and encapsulating it in MQTT packets then uploading it.
When it is used as a JSON data acquisition gateway, the device can be connected to the data acquisition instrument through RS485, and then automatically collect data and convert it into JSON format and send it to the server. The collected data supports Modbus RTU 645 instrument version 97, 645 instrument version 07, and various non-standard RS485 protocols. Users can configure the uploaded data format through the host computer. When uploading JSON, it can support MQTT protocol, HTTP POST protocol and HTTP GET protocol.
