GENERATION AND PUBLICATION OF SHARED TAGSETS

摘要

Systems and methods are provided to facilitate receipt of tag requests from one or more interfaces, based upon which a single tagset is compiled at a controller comprising all the requested tags for a given update rate, whereupon the single compiled tagset is subsequently forwarded to the one or more interfaces. A controller generates a superset of tags associated with an industrial process. Each interface can request a copy of the superset, from which the required tags are selected. The controller receives the requested tags from all of the interfaces and combines the requested tags into a single tagset, for a given update rate, comprising the various parameters associated with the tags. At the selected update rate, the tagset is forwarded to the interfaces. A masterset can be utilized to identify the sequence of tags in a tagset and check code can ensure continuity of the tags in the tagset.

主权项

1. A method, comprising:
receiving, from each of a plurality of controllers each associated with a respective terminal in an industrial process, a request including a set of tags related to process control information and an update rate for each of the tags in the set; compiling, for each of the update rates amongst the requests, a tagset including all tags that share a particular update rate; and forwarding, for each tagset compiled, the tagset at the particular update rate to the plurality of controllers.
