The challenges of designing embedded systems that are able to meet the ever-increasing demands of industrial applications cannot be solved by simply throwing memory and CPU cycles at them. Three characteristics of these applications present particular challenges for the system designer. Typically, they are complex, with diverse devices and software components; they must support sophisticated HMIs; and they have limited computing resources. Persistent publish/subscribe messaging (PPS) can simplify the design of embedded industrial systems.

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 Adobe Flash Lite.
