Abstract:
Arbitrating access to industrial resources as a function of controller identify is provided herein. For example, a unique identifier can be associated with a control module that can distinguish the module from other components of a system. Upon receiving a request to control a resource, the identifier of the requesting module can be associated with that resource. In a case of multiple requests, an arbitrated ID can be chosen and added to an owner queue. The chosen ID is then published and, if the published identifier matches the module identifier, the module can assume control of the resource; if not, the module's request is placed into a request queue for further arbitration. The subject innovation provides for generally applicable arbitration that can reduce redundant code crafted for each module of a system, greatly reducing overhead costs associated with such redundancy.
