摘要： A process control system includes an executive routine located at a first node of a process control system, one or more soft phases located at other nodes remote from the first node and communication software located in the each of the nodes to enable the executive routine to call and execute the soft phases that are at nodes remote from the first node. This operation may reduce loading or communication traffic on the batch executive node and enables the operator to interact with a soft phase at a workstation or node that is convenient to the operation of the soft phase, which makes the operator's task easier and results in faster execution of the soft phase.

摘要： A distributed process control equipment ownership arbitration system and method for arbitrating equipment ownership conflicts are disclosed. Individual control modules representing various process control entities within a process control system define a plurality of lists or queues for storing equipment arbitration information. Requests by one process control entity to acquire ownership over another process control entity are represented by an arbitration token that represents the ownership relationship sought by the acquiring process control entity. Copies of the arbitration token are communicated between the respective control modules and stored in the various arbitration queues defined by the control modules, depending on the status of the acquisition request. Upon receiving an acquisition request from another process control entity, the control module associated with the targeted process control entity decides whether the targeted process control entity is available to be acquired by the requesting control entity based on arbitration rules that are embedded within the control module itself. Once the targeted process control entity has been acquired by another process control entity it may not be acquired by any other process control entity until it has been released by the acquiring process control entity.

摘要： 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.

摘要： Methods and apparatus to apply multiple trip limits to a device in a process control system are disclosed. An example method involves monitoring a value of a parameter associated with the operation of the device and receiving an input indicative of an operational state of the device, where a first input indicates a first operational state and a second input indicates a second operational state. If the first input is received, comparing via a function block the value of the parameter to a first trip limit, and if the second input is received, comparing via the function block the value of the parameter to a second trip limit, and implementing a response based on the comparison.

摘要： A control system, a safety system, etc., within a process plant may each use one or more state machine function blocks that can be easily integrated into a function block diagram programming environment. Such a state machine function block may include one or more inputs, which may cause a state machine implemented by the state machine function block to change states. The state machine function block may determine a next state to which it is to transition based, at least in part, on data indicative of the next state to which to transition, if any. The configuration data may be retrieved from a database based on the current state of the state machine and at least one of the inputs. The state machine function block may also include one or more outputs that are generated based on the state of the state machine.
