The OPC UA protocol is an interoperability standard for the safe and reliable exchange of data in the industrial automation field and other industries. It is platform independent and ensures
seamless interaction of information between devices from multiple vendors. The OPC Foundation is responsible for developing and maintaining this standard.
The OPC UA protocol will be the mainstream standard for the industrial Internet of Things. Therefore, to implement sensors of various protocols and devices to access the OPC UA protocol, you need
to use an OPC UA protocol gateway BL121ML.
The working principle of OPC UA gateway BL121ML: Configure parameters through the configuration software of OPC UA gateway. On the Linux system of embedded hardware, read and write data of electric
meters, Modbus devices and PLC registers, and then save them according to the OPC UA protocol format, and then communicate with OPC UA The server performs data exchange.
OPC UA gateway BL121ML Supports Modbus RTU, Modbus TCP, DLT645, IEC104, BACnet, Lonworks, IEC61850 to OPC UA
