Abstract
A process plant control system includes a batch execution engine that spawns or creates an individual batch process application in a separate application process space for each batch to be run within a process plant. The batch execution engine includes communication software for communicating with batch operator interfaces used to set up batch runs, a master process equipment model reflecting the current state of the equipment and a batch execution manager that creates individual batch processes and spawns each of the individual batch processes to run in a separate application process space. Each of the created batch processes includes batch logic that implements the batch run specified by the user, a copy of the process plant equipment model used to select equipment within the plant and a communication interface for communicating with controllers and other runtime equipment to implement the batch as well as for communicating with the batch execution manager.
