Presentation Transcript

  1. Expanding your Data Redundancy Options • OPC DataHub • Redundancy Options • Combining redundancy with other DataHub features Presenters: Renee Sikes, Product Support Engineer Win Worrall, Product Support Engineer and Developer

  2. Today’s Presentation • Overview of OPC DataHub and Redundancy • Overview of Tunneling • Live Demo • New Features in v7.x • Questions and Answers

  3. OPC Data HubFunctionality Overview http://www.softwaretoolbox.com/opcdatahub

  4. Redundancy Overview • Where is it used? • Mission critical systems • Single point of failure exists • Why is it used? • Increase system reliability and availability • Limit interruptions in sending and receiving data

  5. Levels of Redundancy • Device • Redundant connections between server and multiple devices • Server • Redundant connections between client and multiple servers • Client • Redundant client connections

  6. Types of Redundancy • Cold • Application will only connect to one server at a time • If connection to primary server is lost, connection will be established with secondary

  7. Types of Redundancy • Hot • Application tries to maintain a connection to both primary and secondary servers at all times • Callback is initialized for both servers

  8. Redundancy and the OPC DataHub • Gamma • C-based scripting language • Engine • Dynamic environment • Event driven • Object oriented • Redundancy scripts • Switchover.g • EnableOPCConnection.g

  9. Expanding Redundancy with the DataHub • Combine all features of the DataHub to make most of your data • SMS/Email alerts when fail over occurs • Bridge data between domains • Log to a Database • Data Tunneling • Data Aggregation • Easy set-up

  10. What is Tunneling? OPC Tunneling • Moving OPC Data via simple TCP/IP port connection • Eliminating DCOM and Expanding Data Transport Choices Computer #1 Computer #2

  11. 3 Steps to Tunneling with OPC DataHub • Step 2: Connect Master to Slave • Step 1: Connect Master to OPC Server • Step 3: Connect OPC Client to Slave

  12. OPC TunnelingWhy Tunnel? • No DCOM! • No Remote Procedure Calls (RPC) • Handles Network Interruptions • Handles Low-bandwidth networks • Improve System Performance & Reliability • Reduce Network Traffic • Remove Firewall Issues • Connecting to Non-Windows Systems

  13. Live Demonstration • Hot Redundancy • Primary: Tunnel to Remote OPC Server • Secondary: Local OPC Server • Cold Redundancy • Primary: Local TOP Server v5 • Secondary: Local TOP Server v4

  14. What Tools are Needed? • For all usage scenarios • No tag count limits • No limits on # of clients, # of servers used with a single DataHub • Single PC – 1 DataHub License - $995 • Tunnelling Scenario – 2 DataHub licenses (one per PC) - $1990 • Maintenance Agreements are $199 for the Node License. • Includes 1 Year of Free Upgrades and Support • http://www.softwaretoolbox.com/opcdatahub/html/contract.html • Free Demo Available • http://www.softwaretoolbox.com/opcdatahub/html/free_demo.shtml

  15. New Features 7.x - 2010 • Redundancy support and GUI interface.  Includes domain to domain bridging. • OPC A&E support and GUI interface. • Multi-threaded ODBC with store and forward capabilities • Other changes include: • Tweaks to properties window to allow it to be scaled wider and taller. • New icons and splash screen. • Updated documentation. • OPC UA • Cogent Lightning - Silverlight screen editor and web support.
