Equipped with two serial ports (COM) and one Ethernet port (LAN/WAN), cMT-G03 can function as a serial bridge. Simply by connecting COM1:IN with an upper layer device (HMI/SCADA), and COM2:OUT with the existing device (PLC), cMT-G03 bridges the upper layer-to-device connection while being completely transparent to the system and ensures that existing operation is not affected. This is done without the need for an additional serial port on the device.


Retain Existing Operation
Eliminates the trouble of rewiring or buying new equipment, just plug in with the same communication cable, and the system is immediately connected to IIoT while operated in the same way.

Built-in Support for MQTT and OPC UA
Built-in support for MQTT, OPC UA client and server. MQTT supports standard protocol, Amazon AWS IoT, Sparkplug and many other cloud platforms. OPC UA server officially certified for compliance by the OPC Foundation ensures seamless device integration in any application.

SQL Database Synchronization
Supports synchronizing data log and event log to MySQL, MS SQL database server, for IT personnel to access data easily.

Web Configuration
Supports configuration using web browser, making system maintenance an easy task. Available functions include: system settings, OPC UA settings, PLC communication parameter settings, data log and event log browsing.

EasyAccess 2.0 and Push Notification
