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.

Methods and systems for batch processing and execution in a process system

Methods and apparatus to monitor tasks in a process system enterprise are disclosed. In one example, a method is disclosed that comprises analyzing, using a processor, tasks in an enterprise to determine a criticality of each task and an actionability of each task, ordering, using the processor, the tasks based on the criticality and the actionability of each of the tasks, and rendering, via a display, a first graphic representative of at least a portion of the ordered tasks.

A method of executing a batch process in a manufacturing environment according to a product recipe, such that the product recipe specifies a plurality of actions and a plurality of parameters, includes performing at least one action of the batch process corresponding to a first version of the product recipe, receiving a second version of the product recipe, such that the second version of the product recipe is distinct from the first version of the product recipe, suspending the execution of the batch process prior to completion of the batch process, and resuming the execution of the batch process according to the second version of the product recipe.

Online recipe synchronization in a real-time batch executive environment

Example methods and apparatus to execute an auxiliary recipe and a batch recipe execution are disclosed. A disclosed example method involves executing a first recipe, and before completion of execution of the first recipe, receiving an auxiliary recipe. The example method also involves determining whether the first recipe has reached an entry point at which the auxiliary recipe can be executed. The auxiliary recipe is then executed in response to determining that the first recipe has reached the entry point.

Systems and methods for providing an integrated HMI application for monitoring and interacting with both batch and non-batch processes in a process plant are disclosed. A plurality of independent stand-alone software objects defining various batch process interface views are embedded within a non-batch process control interface application. A blackboard service is provided for storing batch control data used by the various stand alone software objects. The blackboard service may be adapted to communicate with a batch control server to receive batch control data for populating the various batch interface views with data relating to various batch processes being carried out in the process plant and to send instructions for controlling the various batches input by users via the various batch interface views. When executed by a processor, the stand alone software objects defining the various batch interface views read data from and write data to the blackboard service to communicate data between batch process interface views and preserve contextual information between interface views to allow efficient and intuitive navigation between batch process interface views.

Example methods and apparatus to modify a recipe process flow during recipe execution are disclosed. A disclosed example method involves executing a recipe, and before completion of execution of the recipe, receiving process flow change information indicative of a modification to a process flow of the recipe. Process flow rules are then retrieved from a process flow rules data structure. The recipe process flow is modified based on the process flow change information in response to determining that at least one requested change indicated by the process flow change information does not violate one of the process flow rules.

A controller includes a control module to control operation of a process in response to control data, a plug-in module coupled to the control module as a non-layered, integrated extension thereof, and a model identification engine. The plug-in detects a change in the control data, and a collects the control data and data in connection with a condition of the process in response to the detected change. The model identification engine executes a plurality of model parameter identification cycles. Each cycle includes simulations of the process each having different simulation parameter values and each using the control data as an input, an estimation error calculation for each simulation based on an output of the simulation and based on the operating condition data, and a calculation of a model parameter value based on the estimation errors and simulation parameter values used in the simulation corresponding to each of the estimation errors.

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.

Method and system for batch process arbitration in a process control system

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.

Batch execution engine with independent batch execution processes

A process control system capable of executing a function after initiation thereof by a user includes a computer having a memory and a processing unit. A security module stored in the memory of the computer and adapted to be executed on the processing unit of the computer analyzes security information to determine whether the function should be executed. The security information is collected contemporaneously with the initiation of the function and in association therewith.

Function-based process control verification and security in a process control system

A campaign management technique for batch processes enables a process control system user to flexibly create, edit and execute batch process campaigns. The campaign management technique uses a campaign management function that sends messages requesting batch information to a batch executive function. The batch executive function extracts the requested batch information from a database and sends responsive messages containing the requested batch information to the campaign management function. The campaign management function displays the requested batch information to a user via a graphical display and enables the user to select batch information to be included within a batch process campaign. The user can create a campaign having multiple types of batches, which can include special startup and cleanup batches. The campaign management function releases batches of a campaign for execution by the batch executive function according to a user-specified batch execution mode, which may queue a ready batch in the batch executive function prior to the completion of a currently executing batch. A user can add batches to a campaign and/or can modify or delete unreleased batches of a currently executing campaign. Additionally, the campaign management function is tightly integrated with a data historian function and a security function and automatically sends campaign execution messages to the data historian and uses the security function to control user access to the campaign management function.
