Background

Networking OPC DA requires DCOM, which is difficult to configure and not very secure. Learning how to tunnel OPC DA inbound, you can bypass DCOM altogether. The tunnel recovers quickly from network outages, and keeps all OPC servers and clients connected during that time.

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.
