How to connect OPC UA through a data diode

Описание: An OPC UA client cannot connect to an OPC UA server through a data diode because all incoming data gets blocked. OPC UA pub/sub can make outbound connections, but it relies on UDP, which is not practical for most industrial applications. Data delivered over UDP can be damaged, out of sequence, or incomplete.

To solve this problem, the DataHub tunnel/mirror approach encapsulates OPC UA within a unidirectional transport layer that can pass through the diode. On the receiving side, a DataHub instance converts the data back into OPC UA data for the client application.

Skkynet provides Cogent DataHub secure-by-design software and services to let you acquire, aggregate, monitor, control visualize, and network live process data in-plant or over insecure external networks, making it ideal for OT to IT and cloud connections. You can isolate control networks from cyber attacks and integrate industrial data under a unified namespace, all without compromising the plant.
