  3. Definitions and Terms • Interface Level Failover • UNIINT • Data Source/Control System • Disconnected Startup

  4. Agenda • Interface Level Failover • Introduction • Demo of Planned Maintenance • Demo of Uninterrupted Data Collection • Cost Effective Solution • Simple Configuration • Disconnected Startup • Data Collection without PI • Faster Startup Option

  5. PI Server Backup Node Primary Node Data Source What is Interface Level Failover? • Two interface nodes • Communicate to same data source • Only 1 node sends data • Types of failover • Hot, Warm, Cold • Determined by data source and network • Input/Output tags

  6. OPC Typical Network Setup PI Client PI Server Business Network Firewall Process Network OPC Primary Node Backup Node Data Source

  7. Stress Free Maintenance • Data is Available during Maintenance • OS/Security Patch • PI Software Update • Hardware Upgrade • Better decisions

  8. OPC OPC OPC server Network setup for Demo PI Server and Client Business Network Router Backup Node Process Network Primary Node Data Source

  9. Demo Interface Failover during Maintenance

  10. OPC OPC OPC server Network setup for Demo PI Server and Client Business Network Router Backup Node Process Network Primary Node Data Source

  11. Demo Interface Failover with Network Fault

  12. OSIsoft’s Failover Solution is Inexpensive • 3rd Party solutions can be expensive • Limited Hardware Support • Difficult Setup • Expensive Maintenance • Implementation only requires two PCs

  13. Simple and Standardized Configuration • Simple Interface Configuration • Standardized for most interfaces • Basic Tag Configuration 3 1 2 4 1 - /ufo_id* 2 - /ufo_otherid* 3 - /ufo_primary 4 - /ufo_interval * Must be consistent for both nodes

  14. Demo Configuring Interface Failover with ICU

  15. Why six PI tags? PI Tags Data Source Interface 1 Input Tag Point 1 Output Tag Point 2 Source Tag

  16. Why six PI tags? PI Tags Interface 1 Data Source Heartbeat 2, Input Heartbeat 2 Heartbeat 2, Output Heartbeat 1 Interface 2 Heartbeat 1, Input Active ID Heartbeat 1, Output Active ID, Input Active ID, Output

  17. Summary of Interface Level Failover • Normal data collection continues with network or hardware faults • Cost effective solution • Stress Free Maintenance • Simple and Standardized Configuration across all Interfaces

  18. What is disconnected Startup? • Interfaces do not need connection to PI to start • Cached copy of Point DB • Improved startup times • Collect and buffer data w/o PI • Sychronization of Point Changes PI Server Cached Tag List sinusoid cdt158 cdm158 … Interface Node

  19. Development Timeline

  20. Top 10 interfaces • OPC DA Interface (currently ongoing) • Intellution Fix DMACS • Modbus Ethernet Interface • Wonderware InTouch Interface • Foxboro IA Interface (Windows & Solaris)* • OPC HDA Interface • Modbus Serial Interface • OPC Alarms and Events Interface • GE Cimplicity Interface • Interfaces contained in MCN Health Monitor

  21. Conclusion • Simple, Enterprise, Available (SEA) • Simple setup and configuration • Maintenance and improved TCO for the Enterprise • Data Reliability and Availability

  22. OPC OPC OPC server Network setup for Demo PI Server and Client Business Network Router Backup Node Process Network Primary Node Data Source
