Machine vision in Profibus networks
Javier Silvestre-Blanes, Víctor Sempere-Payá · 2002
In this paper, a system for the transport of images across Profibus industrial networks acting as support to the monitoring and control system of industrial processes is implemented and evaluated. The capacity of Fieldbus Data Link (FDL) to support the transport of images and the impact on the performance achieved through the utilization of compressed images are analysed. A communications protocol over FDL is implemented and tests are realized with different image sizes, compression ratios and background traffic which allows for the simulation of various scenarios. Profibus networks have been shown to be capable of simultaneously transporting images with control traffic, which opens up a new range of applications.
