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.
Claims25
An arrangement operable to communicate with a fieldbus network, comprising:
- at least one processor capable of receiving fieldbus function blocks;
- and
- at least one relay which is at least one directly or indirectly coupled to the at least one processor,
- wherein the at least one processor is capable of controlling the at least one relay using at least one of the fieldbus function blocks.
A method for operating at least one relay coupled to a fieldbus network, comprising:
- executing at least one fieldbus function block;
- and
- operating the at least one relay based on at least one output of the execution of the at least one fieldbus function block.
