cMT-G02 Communication Gateway

In an IIoT application, data integration plays a very important role. To achieve data integration, it is essential that the communication between onsite machines and upper layer data management systems (SCADA, ERP...etc.) be seamless. However, in a factory where each controller uses a unique driver for communication, data integration is extremely difficult.

Using the IIoT standard protocols MQTT and OPC UA, the cMT-G02 is an IIoT smart communication gateway. offering the best solution for data transfer and integration.


  • Supports remote access service: EasyAccess 2.0.
    The cMT-G02 installed in a factory can be accessed by users in remote locations, enabling them to obtain operation status of onsite machines and maintain controllers connected to cMT-G02.

  • Supports the Modbus protocol.
    With the cMT-G02 performing protocol conversion, upper management systems can access any cMT-G02-attached controller simply by Modbus TCP/IP.
    In addition, cMT-02's built-in MQTT Server / Client and OPC UA Server enables easy integration of different devices, and facilitate data echange with the upper layer data management systems such as SCADA or ERP.

  • Runs user-defined Macros to perform complex operations 
    Furthermore, Macros supports Conversion Tag, which is used to scale, calculate or convert linear or non-linear data into meaningful data.

  • Built-in 802.11 b/g/n WiFi


IIoT (Industrial Internet of Things) is an industrial framework whereby a large number of devices or machines are connected and synchronized.

MQTT (Message Queuing Telemetry Transport) is a messaging protocol used for IoT applications.

OPC UA (OPC Unified Architecture) is a machine to machine communication protocol for industrial automation developed by the OPC Foundation.
