Express Interface, Xi for Process Manufacturers

  1. 1. DeltaV data integration options and how to choose the right interface for your application (Xi Section) Chris Felts, DeltaV Product Strategist
  2. 2. Express Interface (Xi) Unveiled at Emerson Exchange Xi Server Xi Client Xi Client Xi Client Xi Client Xi Server Plant LAN DeltaV Control Network Jan‘10 Firewall <ul><li>Real-time process data </li></ul><ul><li>Real-time alarms & events </li></ul><ul><li>Historical process data </li></ul>
  3. 3. Potential Security Problems with OPC OPC Server OPC Client OPC Client OPC Client OPC Client OPC Server Plant LAN DeltaV Control Network
  4. 4. What Is Xi? <ul><li>Like OPC, </li></ul><ul><ul><li>Xi is a client server for data exchange between level 2 (control system level) and Level 3 (business / MES level) </li></ul></ul><ul><ul><li>Xi supports the same servers OPC DA, HDA and AE </li></ul></ul><ul><li>Unlike OPC, </li></ul><ul><ul><li>XI is a secure means for real-time and historical data transfer between DeltaV and 3 rd party systems and applications </li></ul></ul><ul><ul><li>Firewall friendly using HTTP/HTTPS </li></ul></ul><ul><ul><li>Uses secure Web services (via WCF - Microsoft Windows Communication Foundation) </li></ul></ul><ul><ul><li>Easy to implement interface </li></ul></ul>Jan‘10
  5. 5. Increased Communication Robustness Xi Server Xi Client Xi Client Xi Client Xi Client Xi Server Plant LAN DeltaV Control Network Jan‘10 If client communications are lost, the Xi interface will retain the current state of the connection and allow the client to re-establish communications without losing configuration Firewall
  6. 6. Unified Interface for All Xi Server Data Xi Server - DA Interface Xi Server - HDA Interface Xi Server - A&E Interface Xi Client Xi Client Xi Client Xi Client Xi Server Plant LAN DeltaV Control Network Jan‘10 Xi client application can access Xi Data Access, Xi Alarms & Events and Xi Historical Data Access data via one Xi interface Firewall
  7. 7. OPC Servers Remain Available OPC DA Server OPC Client OPC Client OPC Client OPC HDA Server OPC A&E Server OPC Client OPC Server Plant LAN DeltaV Control Network DeltaV OPC Servers will remain to provide a migration path and to maintain legacy OPC client communications
  8. 8. Xi and OPC Clients and Servers in the Same System OPC Client OPC Server Plant LAN DeltaV Control Network Jan‘10 Xi Client Xi Client DeltaV Xi and OPC clients and servers can be used simultaneously in the same system with 3 rd party Xi and OPC clients and servers Xi Server OPC Server OPC Client Xi Client OPC Client Xi Client
  9. 9. Xi Details <ul><li>Simplex only for DeltaV v11 </li></ul><ul><li>Workstation based </li></ul><ul><li>Real-time and historical data transfer </li></ul><ul><li>Secure </li></ul><ul><li>High throughput </li></ul><ul><li>Requires some computing background to implement </li></ul><ul><li>Medium cost </li></ul><ul><li>Not many applications available yet </li></ul><ul><li>New interface </li></ul>Jan‘10
  10. 10. Xi Suggested Uses <ul><li>For real-time and historical supervisory control and data acquisition applications </li></ul><ul><li>Where high throughput is required (100 MB typical network bandwidth) </li></ul><ul><li>Where security is required </li></ul><ul><li>Very high tag counts (up to 30k data values per DeltaV Application Station) </li></ul><ul><li>Can tolerant some downtime </li></ul><ul><li>Can interface to some older/legacy hardware using 3 rd party software drivers </li></ul>Jan‘10
  11. 11. Extensive Industry Participation <ul><li>Emerson clients and servers: </li></ul><ul><ul><li>DeltaV </li></ul></ul><ul><ul><li>Ovation </li></ul></ul><ul><ul><li>Syncade </li></ul></ul><ul><li>3 rd Party clients and servers: </li></ul><ul><ul><li>Advosol </li></ul></ul><ul><ul><li>Iconics </li></ul></ul><ul><ul><li>Indusoft </li></ul></ul><ul><ul><li>Matrikon </li></ul></ul><ul><ul><li>Mobiform </li></ul></ul><ul><ul><li>Mynah </li></ul></ul><ul><ul><li>OSIsoft </li></ul></ul><ul><ul><li>SMAR </li></ul></ul><ul><ul><li>TiPS </li></ul></ul><ul><ul><li>10 Xi servers! </li></ul></ul><ul><ul><li>15 Xi clients! </li></ul></ul>Stop by the Xi demo booth in the exhibit hall to see Xi in action!
