BL102 Pro PLC Gateway (PLC/Modbus to MQTT/OPC UA Gateway)

Developed on embedded Linux operation system for robust stability, BL102 is an innovative gateway that converts PLC/Modbus to OPC UA / MQTT protocol. 


PLC/Modbus Gateway BL102 is an industrial IoT gateway that converts various PLC Modbus RTU and Modbus TCP into Modbus TCP, OPC UA, MQTT, Huawei Cloud IoT, AWS, Aliyun, ThingsBoard, and other protocols. 
PLC/Modbus Gateway BL102 downstream supports: Siemens, Mitsubishi, OMRON, Allen-Bradley, Schneider PLCs, upstream supports: Modbus TCP, MQTT, Sparkplug B, OPC UA, Huawei Cloud IoT, AWS, Inductive Automation Ignition SCADA, Aliyun, ThingsBoard,  and other protocols. 
PLC/Modbus Gateway BL102 adopts embedded Linux system, supports TSL, SSL encryption, provides 1 RS232/RS485 optional serial input, 1 power output, 2 Ethernet ports and 2 USB ports, and supports SIM card and SD card. The built-in 4G network or Ethernet access to the Internet has the characteristics of fast speed and low latency. It supports OpenVPN for secure data transmission. 
PLC/ Modbus Gateway BL102 supports routing function and cascaded switch data collection, which is convenient to collect more industrial equipment data. It has complete software functions and covers most of the conventional application scenarios. Users only need to go through simple settings. 



Downlink: Support Siemens, Mitsubishi, OMRON, Allen-Bradley, Schneider PLCs
Uplink: Support Modbus TCP, MQTT, OPC UA, HUAWEI Cloud, Alibaba Cloud, AWS, King Pigeon Cloud
Baud rate 2400bps-115200bps, stop bit supports 1, 2 bits, data bit supports 7, 8 bits. Parity supports None, Odd, Even.
