Page 5: Product Overview
1 Product Overview 1.1 Product Function The GT200-MQ-BMT is a gateway that enables data exchange among Modbus TCP client/servers, a single BACnet IP client, and MQTT network. It can connect a wide range of PLCs (e.g., Siemens, Schneider, etc.), Modbus fieldbus instruments, and BACnet IP controllers to the cloud servers (e.g., Microsoft Azure, Amazon AWS, and custom servers) over a wired Ethernet connection (WAN) using the MQTT protocol. - Page 6 [3] Modbus TCP features: Supports Modbus TCP client and server. Supports up to 36 Modbus TCP connections. Supports up to 128 Modbus commands. Supports function code: 01, 02, 03, 04, 05, 06, 15, 16. Modbus TCP client supports maximum 2048 input/output bytes. ...
