  • Methods and systems for batch processing and execution in a process system
    Patent number: 9804589
    Abstract: A system and method for implementing a control process within a process control system and resolving inconsistencies during execution of the control process includes loading the logical structure of the control process, loading a plurality of instantiation objects or processes when the control process is instantiated, using the instantiation objects to instantiate a procedural element of the control process as the control process calls for the procedural element during execution, executing the procedural element as part of the control process, and deconstructing the procedural element as execution of the procedural element is completed during execution of the control process. Resolution of inconsistencies includes executing a first model of an entity in a controller, executing a second model of the entity in an execution engine, detecting a difference between the models, generating a prompt and receiving an operation instruction to continue the process or abort the process.

  • Method and system for batch process arbitration in a process control system
    Publication number: 20060089739
    Abstract: A method and system for equipment arbitration in a process control system are presented. The method and system include receiving a request for a first resource associated with a first area from a first resource user associated with a second area where the first and second areas are distinct. The method and system automatically determine whether the first resource is available for use by the first resource user.
