  1. APIs forintegration

  2. APIs, Possibilities • What APIs do we have? • How can we use them for integration? • New functionality/project deviations • Future APIsAPI = Application Program Interface

  3. APIs, Possibilities • What APIs do we have? • DB Server API • ActiveX COM DB Server API • ODBC • APIs on different layers • After Sales opportunities

  4. APIs, DB Server API • DB Server API • Supports a lot of functions: • Authority • Start of SPIDER program (Avanti sndmsg) • Read real time data including quality flags • Read/update historical data including quality flags. Transparent UDW 200 or Avanti TTD • Dynamic SQL • Read/write server disk files • Redundancy transparent for the user application • etc... • Available on multi platforms UNIX/VMS/Windows • API is a DLL (Windows) or a shared library (UNIX/VMS)

  5. APIs, ActiveX DB Server API • ActiveX COM DB Server API • Functionality about the same as for the DB Server API • Excellent support for writing Visual Basic applications • Active Server Pages (ASP) support

  6. APIs, ActiveX DB Server API

  7. APIs, ActiveX DB Server API

  8. APIs, ODBC • ODBC • Supports a lot of functions: • Authority • Read/update real time data • Read/update historical data including quality flags • Virtual tables => extremely easy to set up a query (you have to know something about the contents of the database) • Insert/Delete records in Avanti • Redundancy transparent for the user application • Supported by MS Office • MS Query (to set up the select statement) • MS Excel SPIDER Reports • MS Access direct import of Avanti data • Supports tools that support ODBC

  9. APIs, ODBC

  10. APIs on different layers

  11. APIs, Possibilities for After Sales • After sales opportunities • Experience • NOINA has sold the ODBC-driver • SEUTA has sold Excel to SPIDER release 1 using DB Server API • DEUTA offers integration solutions by means of ODBC and DB Server API • supports old releases • Product wrapping is needed • Identified and known for different releases

  12. APIs, Possibilities for After Sales • After Sales opportunities (cont.) • In priority (go for money) • Win a soft support upgrade contract • Look at integration aspects between different systems and SPIDER • Suggest different solutions • Sell Excel using the report package • Sell ODBC driver • Sell DB Server API/DB Server API COM-version

  13. APIs, Possibilities for integration • How can we use the APIs for integration? • Here follows examples of what have been done in DEUTA

  15. Open System architecture Open Systems based on “independent“ Standards • Software portability: IEEE POSIX Operating System Interface • Standards on workplaces (Human Machine Interface, HMI) • Database server: Structured Query Language (SQL) • Database Interface to the Office-world (ODBC) • Communication standards: e.g. ISO/ OSI- Reference Model • Remote control system protocols : RP 570/ 571, IEC 870-5-104 • ...

  24. The new IT-Integration concept is a real Milestone in network operation Our objectives • We help to optimize the business process four our customers. • We use IT- technologies for the integration of different software-components.

  25. APIs, Possibilities for integration • New functionality/project specials • Use the APIs to implement new functions like: • Stand alone calculations of various kind • Operators Diary (in the WS400 NT) • …. • Use the APIs to implement project specials • Supports upgrades of SPIDER (The API used is still supported in next release) • No messing up in standard implementation

  26. APIs, Possibilities for integration • Future APIs • Many more APIs will come • Release independent • Also available on integration platforms • SPIDER IDL (SIDL) • DAIS (OPC) • DAF/CIM • HMI third party API support • Java support via IIOP (Internet Inter-ORB Protocol) transport module will enable all coming SIDL based APIs to work with Java (RMI Remote Method Invocation) • JDBC support is possible to buy for the existing ODBC-driver

  27. APIs, Possibilities for integration • SPIDER Interface Definition Language (SIDL) • Opens up the functions of SPIDER to the external world (compare MS) • Supports different hardware as well as different platforms • Supports loose coupling of functions • Compare with MS closed to an open environment • Good performance • To guide and support development • Promotes modules/components • It is an ongoing development project (C-28)

  28. SPIDER IDL Framework Presentation • The framework is a ‘middleware’ with similarities to COM and CORBA but differs in some areas. • Similarities • IDL (SIDL) • Name Server • Support at least two of the three OO criteria's • Encapsulation • Polymorphism • (Inheritance (not supported by COM, only as aggregates)) • Differences • Supports system configuration and supervision • High performance although very flexible • Ease of use, low threshold for new users • Supports heterogeneous networks (as do most CORBA impl)

  31. APIs, DAIS • OMG DAIS (Data Acquisition for Industrial Systems) • Is a becoming standard • Initiated by ABB • Subscription of process data • Compatible with OPC (process data) • Used in the SPIDER Cadops integration • Based on the SPIDER IDL Framework

  32. APIs, DAF/CIM • OMG Utility Management Systems DAF (Data Access Facility) • API for retrieval of data according to the structure defined in CIM (Common information Model) • Mapping of CIM and Avanti structures • Ongoing work in US as well as in Sweden • Publishing via a DAF API
