Abstract:
An arrangement operable to communicate with a fieldbus network and operate an attached relay and a method for implementing such arrangement is provided. The arrangement and method provide conventional discrete outputs from a fieldbus device using standard fieldbus function blocks, such as those used for Foundation and Profibus fieldbus networks. The arrangement and method may facilitate the integration of traditional discrete relay functions into these more advanced digital fieldbus networks, and also utilize additional functions available to standard Foundation fieldbus and Profibus fieldbus network devices.
