DAS Software

  • We shall provide Lab view Runtime platform on Lab view development environment for developing the real tome software and real time simulation
  • We shall provide BSP, library, API & test applications for the I/O models to test and clear the ATP of installation

The lab view Run-Time Platform from Lab VIEW-built applications relates to the concept of componentbased software development and distribution. The world of software today is a component-based world. No longer do we develop and deploy monolithic applications. Rather, we develop software that reuses common components as often as possible. When we deploy this software, more than a single file is almost always required. Applications that use the same components are then able to use the same common files, resulting in smaller disk usage than if each application included all required components. Perhaps even more importantly, developing component-based software allows us to update individual components separately from the software that uses those components.

The principal complaints about Lab VIEW applications were their large size. A contributing factor to the size of Lab VIEW applications was that the Application Builder includes a copy of the Lab VIEW Run-Time Engine in every application. Using the principles of component-based software, one way to solve this problem was to separate out the common component, the Lab VIEW Run-Time Engine, so that all Lab VIEW-built applications on a system could use the component.

Many of the technologies that we use in Lab VIEW today are available only as components. Examples include Data Socket, NI-Reports, and the Mesa graphics library for displaying three-dimensional controls and indicators.
