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.
Claims26
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,
- wherein the at least one processor utilizes the fieldbus function blocks to control the at least one relay.
A method for operating a relay arrangement coupled to a fieldbus network, comprising the steps of:
- executing at least one fieldbus function block;
- and
- operating at least one relay in response to the execution of the at least one fieldbus function block, wherein the execution of the at least one fieldbus function block and operation of the at least one relay are performed within a single field device.
