LM Gateway101-IoTlite Gateway IoT Gateway MQTT Supports For Acquisition Protocols Modbus BACnet PLC

Description:
LM Gateway101-IoTlite data acquisition gateway provides a RS-485 serial port and a 10/100Mbps Ethernet port. The gateway has embedded data acquisition drivers for Modbus, BACnet, OPCUA, DLT645, Siemens PLC, etc. As a Modbus RTU and Modbus TCP server, it can provide data to the outside world. The gateway and the cloud platform use the instant messaging protocol MQTT to transmit data, and the gateway can be used as an MQTT client to support for connection to Alink (for Alibaba Cloud) Tlink, etc. The data points of the gateway are pushed to the cloud through the subscription and publishing mechanism, and the cloud can read and write operations to the collected devices through the gateway, and supports offline storage.

Gateway Functions:
1. Data Services
* As an MQTT client, the gateway supports for connection to Alink (for Alibaba Cloud), Tlink, IoT data center, and other private clouds, etc., and pushes the data points of the gateway to the cloud through the subscription publishing mechanism. The cloud can read and write operations to front-end devices through the gateway.
* As a Modbus RTU and Modbus TCP server, the gateway provides data to the outside world, supports 0x, 1x, 3x and 4x functional areas, and supports int16, int32, float32 and various data types with big and small end changes.
* Gateway provides http server, supports GET and POST. Users can retrieve the real-time data and stored historical data of the gateway through the http server interface.
* Supports data points up to 1024.

2. Data Operation
Support arithmetic operations, functions, logical judgments, and Boolean operations

3. IoT
The gateway can communicate with the cloud server through the MQTT protocol. Support for Alink (for Alibaba Cloud), Tlink and other private cloud servers. We have launched our own Industrial IoT Cloud Platform, which can facilitate users to verify IoT applications such as gateways, cloud services, WeChat public accounts, etc.

4. Alarms and Events
The alarm and event page allows users to set the trigger conditions of the event. Trigger an event when a condition is met. When the state transitions from satisfying the condition to not satisfying the condition, the execution event is released.

5. Tasks and Plans
Users establish the task plan, specify the week and time period to set the value of multiple points. Before using the task scheduling function, please calibrate the time of the gateway

6. Javascript Script Editing
JavaScript script editor built-in functions. Users can implement custom logic control by editing the script language, and can customize serial communication: call the built-in function to send the message to the serial port, return the received message and parse it.
