1 OPC DA Tunnelling Presenters: Colin Winchester, VP Operations Win Worrall, Application Engineer  OPC DA Tunnelling  PC to PC without DCOM  Encryption between systems  Across Firewall though single port

2 OPC DA Tunnelling Agenda  OPC Tunnelling  Overview of the OPC Data Hub  Live Demonstration  Additional Application Examples  Questions & Answers

3 OPC Tunnelling What is Tunnelling?  Moving OPC Data via simple TCP/IP port connection  Eliminating DCOM and Expanding Data Transport Choices Computer #2Computer #1

4 How Does OPC DA communicate between PC’s  An OPC Client connects to an OPC Server through COM  An OPC Client connecting to an OPC Server on a different machine connects through DCOM and must be authenticated. PC – 1 OPC Client COM run-time Security Provider OPC Client PC – 2 OPC Server COM run-time Security Provider OPC Server I want to connect to you Tell me your login name and password! My user name is “fred” and password is “*****” Let me check my Access Control List…. Yes, you are on my list… I will grant you access!

5 OPC Tunnelling Why Tunnel- General?  No DCOM!  No Remote Procedure Calls (RPC)  Remove Firewall Issues  Network Interruptions – DCOM timeouts Computer #2Computer #1

6 OPC DataHub Functionality Overview http://www.softwaretoolbox.com/opcdatahub System Monitoring OPC Tunnelling

7 OPC Tunnelling Why Tunnel with DataHub?  No DCOM! Or RPC – Easy to configure  Remove Firewall Issues – single port  Network Interruptions – more then DCOM  Low-bandwidth or Reduce Network Traffic  Improve System Performance & Reliability  Increase Data security (passwords & SSL)  Connecting to Non-Windows Systems  Connect between any NT or later Windows OS

8 Aggregation & Tunneling Additional Application Examples Multiple OPC Servers & Clients  Each Client makes it’s own connection to each OPC Server  High network utilization, negative impact on control network With Aggregation – Efficient Data Flow OPC Clients OPC Servers & OPC DataHub Without Aggregation – a maze of connections and redundant data flow! OPC Clients OPC Servers & OPC DataHub

9 Aggregation & Tunneling Additional Application Examples Tunneling from Single OPC Server to Multiple Clients  No DCOM headaches  Firewall Friendly OPC Server OPC Client OPC DataHub

10 Aggregation & Tunneling Additional Application Examples Tunneling Multiple OPC Servers to Single Client  No DCOM headaches  Firewall Friendly OPC Client OPC Servers OPC DataHub

11 OPC Tunnelling Why Tunnel with DataHub?  OPC DataHub tunnels DATA  Any data source – OPC DA, DDE, ODBC  Any data that DataHub can read  Clients connected to OPC DataHub always get an answer  Multiple clients on same PC, still one remote connection to remote OPC sources, managed by OPC DataHub.  Other Tunnellers  Tunnel commands at the OPC protocol level and can only tunnel OPC Data!  Make connected clients wait on network timeouts  Multiple clients on same PC talking to remote OPC server = multiple connections

12 Other Approaches  VPN  Does not solve  DCOM, Network stability, bandwidth and crossing domains  OPC XML/DA  Not secure, more over head, not for high speed, limited products, OPC UA  OPC UA  Requires all products to support it  DataHub will add this

13 3 Steps to Tunnelling with OPC DataHub  Step 1: Connect Master to OPC Server  Step 2: Connect Master to Slave  Step 3: Connect OPC Client to Slave

14 OPC Aggregation &Tunnelling  Live Demonstration Win’s PCColin’s PC

15 Aggregation & Tunneling Additional Application Examples Aggregating & Tunneling to MES/ERP Systems  Aggregation Consolidates Plant Floor Data  Tunneling gets it to the front office  ODBC, API’s, DDE, Scripting, TCP/IP Available to tie in to MES/ERP

16 Aggregation & Tunneling Additional Application Examples Aggregating & Tunneling OPC, Linux, ODBC and Excel!  Pull data from OPC Server Locally  Tunneled data to and from remote Linux Server – or any OS  ODBC Database connections to Database Server  All data pulled together in DataHub, charted in Excel with drag+drop OPC Server Database Server TCP/IP Tunnel

17 Aggregation & Tunneling Additional Application Examples Tunneling to Bring HMI/SCADA Data Where You Need It  Aggregate data when needed  Tunneling to get the data where you need it  Web Interface Serves the data where & how you want it  ODBC, API’s, DDE, Scripting, TCP/IP to do what you want! DataHub InTouch HMI TOP Server InTouch to OPC Driver Standard TCP/IP Single Port Connections DataHub GE Proficy iFix DataHub RSView DataHub Front Office Factory Floor

18 What Tools are Needed?  For all usage scenarios  No tag count limits  No limits on # of clients, # of servers used with a single DataHub  Aggregation on a Single PC – 1 DataHub License - $995  Aggregation + Tunnelling Scenario – 2 DataHub licenses (one per PC) - $1990  Demo site will pop-up after this presentation:  http://www.softwaretoolbox.com/opcdatahub/html/free_demo.shtml
