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 astute 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.

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： An I/O-abstracted configuration is defined for a field device that has not yet been assigned or allocated to communicate via a particular I/O device or I/O network within a plant, and this configuration is stored in a device placeholder object in a back-end environment of the plant. Thereafter other objects, modules, applications, user interfaces, etc., that are to execute in the back-end environment of the plant to communicate with the field device during on-line operation of the plant may be designed, built, configured, and tested using the device placeholder object without any actual communications with the field device and without assigning the device placeholder object to a particular I/O channel or I/O network. A commissioning system which may create and store one or more device placeholder objects in a database within the back-end environment of the plant includes an execution engine that executes one or more other back-end environment objects to be commissioned and tested, and a communication interface that determines, from the device placeholder object if a field device is in an I/O-unallocated device state. If so, the communication interface uses the configuration data stored in the device placeholder object to verify that the form, format, and configuration of the object being tested is correct to properly communicate with the field device. Moreover, a simulation engine can generate simulated device signals to enable further testing of the object.

摘要： A communication bus suitable for use in a hazardous area of a process plant includes a first transmission path adapted to communicate electrical signals in a first direction, and a second transmission path adapted to communicate electrical signals in a second direction. A safety device is coupled to each of the first and second transmission paths and includes a control unit adapted to detect a fault condition associated with the communication bus. The safety device further includes a switch unit adapted to interrupt the flow of electrical signals along each of the first and second transmission paths in response to the detected fault condition. In this manner, the detection circuitry of the communication bus automatically reduces or prevents the occurrence of sparks or arcing in the event of a fault condition associated with the communication bus.

摘要： An integrated bus controller and power supply device includes a typical or standard bus controller and a bus power supply disposed in a common housing, the size and external configuration of which may match a standard bus controller device associated with a typical I/O communication network. The bus controller may store and implement one or more control routines using one or more field devices connected to the I/O communication network while the bus power supply generates and provides the appropriate power signal to the bus of the I/O communication network, the power signal being used to power the field devices connected to the I/O communication network. The integrated bus controller and power supply device can be easily connected to the bus of the I/O communication network to provide both bus controller functionality and bus power supply functionality on the I/O communication network, without the need of configuring and attaching separate, dedicated bus controller and power supply devices to the bus and having to wire these devices together using multiple different terminal blocks.

摘要： A versatile controller that can be used as either a stand-alone controller in a relatively small process plant or as one of numerous controllers in a distributed process control system depending on the needs of the process plant includes a processor adapted to be programmed to execute one or more programming routines and a memory, such as a non-volatile memory, coupled to the processor and adapted to store the one or more programming routines to be executed on the processor. The versatile controller also includes a plurality of field device input/output ports communicatively connected to the processor, a configuration communication port connected to the processor and to the memory to enable the controller to be configured with the programming routines and a second communication port which enables a user interface to be intermittently connected to the controller to view information stored within the controller memory. When used in a distributed process control system, the controller platform may be used as a remote input/output device and the ports of this remote input/output device may be logically mapped to controllers within the distributed process control system in a manner that is different than the physical connection between such controllers and the remote input/output device.
