Building Embedded Industrial Applications with PPS

A Persistent Publish/Subscribe (PPS) messaging model is an excellent choice for embedded industrial systems which must integrate many disparate devices and components, as well as support a sophisticated Human-Machine Interface (HMI). PPS messaging simplifies the design of these systems and facilitates implementation of HMIs built with disparate technologies, such as HTML5, OpenGL ES, Qt, Elektrobit Guide or Crank Storyboard.
