SCADA Integration Infrastructure: The RTAP Development Environment
Today's environment requires a SCADA system to be very open for application integration and flexible enough for third parties to easily add new, unique functionality. For years seasoned RTAP users have been developing their own added value applications on top of RTAP. Examples of value added applications built onto RTAP include:
- custom leak detection, hourly/daily accumulations and power/pressure allowables applications in pipelines.
- Start-up management, integrated load management and network management applications in power.
- Cost management and capacity analysis, energy management applications for transportation.
- Energy management, pump optimization & scheduling applications in water.
At the heart of RTAP's superior flexibility and integration capabilities is an extensive, documented set of Application Programming Interfaces (API) that open the core real-time services to application programs. Applications can access the database, event manager, timekeeper, and process scheduler, as well as the scanning, alarming, history, and messaging systems. RTAP functions also enable you to use a range of real-time services in creative ways that extend the abilities of the core platform.
For maximum performance, the base API is provided for C and languages that can call C functions. RTAP also offers a Java interface that provides an object-oriented interface to RTAP services for Java developers writing applications using EJB, J2EE or JSP.
In addition, various scripting languages can be used to access RTAP services and develop custom applications. These include Javascript, VBA and TCL.
