  2. What is the Issue? • Customers want to network OPC clients and servers running on different platforms, in different domains, and on completely separate networks…

  3. HMI-30 Agenda • OPC Tunneling – What is the Issue and Why? • Dan Muller, , Product Development Dir. • The Real DCOM Issue… • DataWorX32 OPC Tunneling – The Solution! • DataWorX32 OPC Tunneling – Demonstration! • The Quiz…

  4. In the Beginning Life Was Easy Graphics Alarming Trending

  8. …And Expanded… Graphics Alarming Trending The DCOM Nightmare… Read Only Access OPC/IO Server(s) Read & Write Access Other Business Systems

  9. The Real DCOM Issue Presented by Dan Muller Product Development Director Cyberlogic

  10. Why is DCOM an Issue? • DCOM and related security issues can prevent OPC communication from working. • Latency of DCOM error reporting is unacceptable for real-time systems.

  11. Dealing with DCOM “Can’t I just set up the security settings within Windows?” • Yes – in theory. • This can be done for small, simple systems. • For complex systems, this can be a nightmare to administer.

  12. The DCOM Problem… • Accessing across domains and workgroups: domains must trust each other. • Some users may not have the privileges needed. • Requirements specific to different operating systems.

  13. The DCOM Problem… • Firewalls. • System-wide DCOM settings. • Callbacks. • Access, launch and activation permissions.

  14. The DCOM Problem… • Additional settings required for OPC servers. • Hard-coded security settings.

  15. The DCOM Problem… • Coordinating with multiple IT administrators at different locations. • Maintenance as users, networks and systems change.

  16. The DCOM Problem… • The latency of DCOM error reporting.

  17. The DCOM Solution… • OPC Unified Architecture (UA) should/will eliminate this problem in the future. • A tunneler product solves this problem today, by eliminating DCOM completely.

  18. Why ICONICS? • Only a handful of companies make tunneling products. • One company in Germany and another in Canada offer tunneler products that work with OPC DA only. • One company in Tunisia offers one product for OPC DA and one product for OPC A&E. • ICONICS DataWorX Tunneler product supports OPC DA, A&E and HDA.

  19. ICONICS DataWorX Tunneler… • Let’s listen to ICONICS’s tunneling product capability with a demonstration, using a Cyberlogic OPC Server.

  20. DataWorX V9 – The Solution -Lite Version V9 -Tunneler Kit (pair) -Standard V9 -Professional V9 -Redundancy (pair)

  21. DataWorX V9 – The Solution

  22. So, Why is DCOM an Issue? • Complexity to Configure DCOM • DCOM is Not Real-Time • DCOM can take up to 6 minutes to detect and notify when a connection failure has occurred • DCOM is Not Firewall Friendly • Firewall pass through requires many open ports • Major Security Issue

  23. DataWorX32 - OPC Tunneling • Bridges any OPC Server to any OPC Client • Firewall and Internet friendly • Supports Tunneling of • OPC DA • OPC AE • OPC HDA • Alternative to conventional MS DCOM communications

  24. OPC Tunneling Architecture • Based on ICONICS’ patented GenBroker™ communication – versus DCOM • Graphical user interface provides centralized management of all remote connections

  25. OPC Tunneling Architecture

  26. OPC Tunneling Key Features • Supports latest OPC Industry Standards • OPC Data Access 3.0 • OPC Alarm and Events 1.1 • OPC Historical Data Access 1.2 • Auto-discovery of remote OPC DA, A/E and HDA Servers • Simple to set up and configure • Supports OPC browser interfaces over LANs, WANs, and the Internet • Supports TCP/IP and SOAP/XML communication protocols

  27. OPC Tunneling Security • Most Competitors Have None! • Tunneling Client sends credentials to Server side of Tunnel • Server Side • Obtains authentication • Uses “impersonation” to create the server under the specified user account • Each Tunneling connection can have it’s own credentials

  28. OPC Tunneling Security • If the specified User does not have access rights to the destination OPC Server, then the OPC Tunnel creation fails and an “Access Denied” is reported • The access is controlled by the DCOM Configurator at the remote location. (DCOM in Server, not across the Network)

  29. DataWorX32 - OPC Tunneling DEMONSTRATION!!!

  30. The Internet ICONICS WWCS Company Architecture Boston, MA Prague, Czech Wireless Routers Switches OPC Servers OPC Servers Foxboro, MA

  31. 4 Simple Steps to Create a Tunnel Click on OPC Tunnel icon Browse to DA, AE or HDA server Open Right click, select ‘Make OPC Tunnel’ That’s It !

  32. DataWorX32 - OPC Tunneling • Bridges any OPC Server to any OPC Client • Firewall and Internet friendly • Supports Tunneling of • OPC DA • OPC AE • OPC HDA • Alternative to conventional MS DCOM communications
