OPC Gateway - OPC Data Bridging
Project Introduction:
DataExChange OPC Server can pass information from one device on to another; for example, data from one brand of PLC shared with another I/O device. In the past, one would have to write programs to translate and move data from one server to another. DataExChange OPC Server provides this server-to-server data exchange, serving as an "OPC bridge" between two or more servers. OPC bridging is a unique and powerful feature of DataExChange OPC Server, providing "bridging" between OPC servers of various types.

OPC to Modbus (TCP/RTU) Slave - OPC Data Bridging
Project Introduction:
OPC to Modbus (TCP/RTU) slave can connect to any of the OPC Server and convert to the Modbus TCP or Modbus RTU/ASCII slave.
It can avoid to adjust the DCOM setting. Besides, some of the SCADA or device only support the Modbus master protocol. It's helpful for the integration.

OPC to MQTT Client
Project Introduction:
OPC to MQTT Client connect to any of the OPC Server and convert to MQTT Broker.
The quality of service (QoS) assigned to the message.
There are three levels of QoS: QoS0: at most once,QoS1: at least once,QoS2: at exact once
The retained flag serves two purposes depending on whether the message it is associated with is being published or received.MQTT Server will retain and sent it when add subscribe. Or MQTT Server won't retain.
