摘要： A software object approval system is integrated with a process control or safety system environment and, in particular, with a process control or safety system design environment to implement and manage electronic approval of new software objects created within the process control and safety system environment. The software object approval system electronically generates identification information representing a group of entities whose approval is needed prior to implementing a software object within the process control or safety system. The system may then send the software object to the entities and receive from each entity an electronic indication regarding approval of the software object. The approval system prevents the process control or safety system from implementing the software object until each entity within the group of entities approves the software object.

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 or may not cause a state machine implemented by the state machine function block to change states. The state machine function block may also include a plurality of outputs. Output configuration data associated with the function block may indicate values of the outputs of the function block for each of the states of the state machine. The state machine function block may use this output configuration data to determine its outputs when in a particular state.

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.

摘要： A technique for configuring a Boolean logic function block displays a matrix associated with the Boolean logic function block on a display screen of a computer. A programmer may then enter configuration data into the matrix to configure the Boolean logic function block. The matrix may include a plurality of cells, some of which correspond to variables to be used in generating a function block output, and the programmer may enter configuration data into the cells. The configuration data entered into cells are indicative of logic functions to which the variables corresponding to the cells are to be provided as inputs.

摘要： A Unified Threat Management System (UTMS) for securing network traffic in a process control system may comprise network devices configured to receive network traffic related to the process control system and including a ruleset received from an external source. The ruleset may include one or more rules defining a condition to accept or deny the network traffic received at the network device. The state of the network device may be integrated into the process control system as a process control object or variable, thus allowing the state and other UTMS and component network device parameters and variables to be displayed to an operator at a workstation within a graphical process control system environment. The network devices may also communicate with a perpetual service that proactively supplies the devices with rulesets to meet the latest security threats, threat patterns, and control system vulnerabilities found or predicted to exist within the network.

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： A configuration system for use in a process control network having a controller, a first device network that communicates using a first input/output protocol, such as a Fieldbus or a HART device protocol, and an AS-Interface device network that communicates using an AS-Interface input/output communication protocol includes a configuration database that stores configuration information pertaining to the first device network and configuration information pertaining to the AS-Interface device network, a data access routine that automatically requests configuration information pertaining to the first device network and configuration information pertaining to the AS-Interface device network and a configurator that configures the AS-Interface device network based on the AS-Interface device network configuration information. The configurator stores the AS-Interface device network configuration information in the configuration database along with configuration information pertaining to the first device network. A documentation routine accesses the configuration database to display a process control documentation schematic illustrating the configuration of the first device network and the AS-Interface device network within the process control system.

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： Devices and applications within a process control system make data generated therein available using a really simple syndication (RSS) XML communication format, thereby making this data easily retrievable from the plant and useable for various purposes both within and outside of the plant. The RSS data communications may provide RSS data for use in control of the plant or for use in other applications not directly associated with the control of the plant, including third party applications run on devices outside of the plant. The RSS data sent from one device to another may include enclosures, such as video, audio or text files, or may include references such as hyperlinks to other sources of information stored on the receiving device or on a further device that may be accessed and used to understand or process the RSS data.
