Industrial Ethernet Series
Modbus RS485 to WAN MQTT Gateway
GT100-MQ-RS
909-490-7557
+1-909-490-7557
The GT100-MQ-RS gateway connects PLCs (including Siemens, Schneider, and others), fieldbus instruments, and serial devices to MQTT cloud platforms such as Microsoft Azure, Amazon AWS, or custom MQTT brokers over a wired WAN connection. Designed for modern IIoT (Industrial IoT) environments, it provides reliable real-time data communication and remote monitoring for industrial applications.

Connection
- Connect the device to the Internet via a network cable.
- Connect the power supply as follows.
Note: Do not power on the device until all connections are complete.
Optional: Connect power supply II for backup redundancy. - Connect the serial devices.
Note: The GT100-MQ-RS does not have a built-in terminal resistor on the RS-485 serial interface. When connecting multiple RS-485 serial devices, it's recommended to connect a terminal resistor (120Ω, 1/2W) in parallel at both ends of the communication lines to ensure stable communication.
- Connect the GT100-MQ-RS to the PC via an Ethernet cable.
- Power on the GT100-MQ-RS.
Configuration
Please see "SST-MQT-CFG Software Content" for details.
- Download the configuration software SST-MQT-CFG from www.sstautomation.com and install it. Open the software and select the GT100-MQ-RS product.
- Configure the Client (MQTT Client configuration).
- Add or edit an MQTT topic.
- Configure the Ethernet and Subnet Interface parameters.
- Configure the properties.
- Check the mapping buffer and the property names. Use the "Auto Mapping" and "Name Properties in Order" functions.
- Save the configuration and download it to the GT100-MQ-RS over the network.
Notes:
- Ensure that the GT100-MQ-RS and your computer are on the same subnet.
- If you cannot discover the gateway, please test the network connection first. Please refer to the note "How to Use the Ping Command" located on our Support page on the sstautomation.com website.
- If you can't discover any gateways, after powering on, press and hold the button for 3 seconds. This restores the IP address to 192.168.0.10, allowing the device to be discovered on the same subnet as the computer for uploading and downloading configurations.
SST Connect APP is an essential component of the Industrial Internet of Things (IIoT) software system developed by SST Automation. It is designed to remotely manage different industrial devices, machines, and systems in order to improve efficiency, reduce downtime, and optimize production processes, etc.
