Tunnel A&E

Reliable networking of OPC A&E servers and clients

Do you need to collect OPC A&E data from multiple servers at local or remote locations? Or connect to OPC A&E servers on a different network? Now you can easily and securely tunnel A&E, by adding the A&E feature to the DataHub DA Tunneller or DataHub UA Tunneller.

Bring all your A&E data into a single A&E client.  Convert OPC A&E to OPC DA or UA.  Tunnel through proxy servers and DMZs, eliminating IT challenges. Detect network breaks in milliseconds, and recover from them smoothly, without breaking the OPC A&E client connection.  Carry over all the benefits of DataHub OPC tunnelling to tunnel A&E, with this unique OPC A&E add-on feature.
