LM Gateway403-IoT
IoT Gateway
LM Gateway403-IoT data acquisition gateway, based on a solid hardware platform design, a complete software kernel. Provides 4 RS-485 serial ports and 2 10/100 Mbps Ethernet ports，and supports 4G modules.The gateway is embedded with Modbus, BACnet, DLT645 and other data acquisition drivers. It provides proprietary protocol driver integration. The gateway acts as Modbus RTU. The Modbus TCP server provides external data. The gateway and cloud platform use the instant messaging protocol MQTT to transmit data. The gateway data points are released through subscription. The mechanism is pushed to the cloud, and the cloud can read and write to the front-end device through the gateway.

Gateway acts as Modbus RTU, Modbus TCP server provides external data
Support 0x, 1x, 3x, 4x, 4 functional areas
Supports int16, int32, float32 and various data types
The gateway provides an http server, which supports two common methods of GET and POST. Users can retrieve the real-time data and stored historical data of the gateway through the http server interface.
The gateway can serve as an MQTT client, connecting Alink (Alibaba Cloud), Baidu Cloud, Tencent Cloud, Tlink and other private clouds.
Push the data points of the gateway to the cloud through a subscription and publishing mechanism. The gateway reads and writes the front-end equipment.Romi Measurement & Control launched the IoT data center, which is convenient for users to verify IoT applications such as gateways, cloud services, and WeChat public accounts.
