摘要： An interactive software-based network design tool that may be used to simulate and view the operation of a wireless mesh device network used in a process plant, such as a wireless HART device network, allows a user to create a model of a wireless network, input several design requirements, and automatically generate and view communication routes and schedules for the wireless network. The network design tool provides an interactive graphic interface for the addition, removal, and positioning of nodes and devices within the wireless network and a menu including several interactive screens for specifying threshold values, network topology selections, routing preferences, and other configuration parameters related to generating and optimizing communication routes and schedules within the wireless mesh network. The network design tool automatically applies a set of optimization rules along with the parameters input by user to the network model in order to generate efficient network configuration data.

摘要： A method of routing a data packet between a first node and a second node on a communication network includes defining a first graph through the first node and the second node and zero or more intermediate nodes, associating several nodes which belong to the communication network with the first graph, associating a first unique graph identifier with the first graph and providing at least partial definitions of the first graph and the first unique identifier to at least some of the nodes associated with the first graph. The method then sends data packet with the graph identifier from the first node, and directs the data packet to the second node via the zero or more intermediate nodes using the graph identifier. This method may include forwarding the packet to a neighbor node of an intermediate node if the intermediate node and the neighbor node are nodes associated with the first graph and if the intermediate node and the neighbor node are connected by at least one direct communication connection.

摘要： A mesh communication network for use in, for example, process control plants includes a plurality of network devices transmitting and receiving data according to a network schedule defined as a set of concurrent overlapping superframes, and along a set of graphs defining communication paths between pairs of network devices. A network manager residing in or outside the communication network develops a routing scheme for the network by analyzing the topology of the network and defining a set of graphs for use in routing or transmitting data between various nodes of the network, each graph including one or more communication paths between pairs of network devices. Concurrently or consequently, the network manager defines the network schedule in view of at least transmission requirements, power availability, and signal quality at each network device. If desired, the network manager may begin to define the network schedule upon completing the definition of the graphs of the communication network, so that the network manager may define the network schedule in view both the defined graphs and the transmission, power, etc. parameters associated with each network device.

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.

摘要： A transactional data communications system and method communicates information within an enterprise having a process control system and a plurality of information technology systems that are communicatively coupled to the process control system via a web services interface and a transactional information server. The system and method generates transactional process control information and formats the transactional process control information based on an extensible markup language input schema to form formatted transactional process control information. The system and method sends the formatted transactional process control information to the transactional information server via the web services interface and maps the formatted transactional process control information to an extensible markup language output schema associated with one of the plurality of information technology systems to form mapped transactional process control information. The system and method then sends the mapped transactional process control information to the one of the plurality of information technology systems.

摘要： A diagnostic tool automatically collects and stores data indicative of a variability parameter, a mode parameter, a status parameter and a limit parameter for a multi-variable function block associated with one or more devices or loops within a process control system, processes the collected data to determine which devices, loops or function blocks have problems that result in reduced performance of the process control system, displays a list of detected problems to an operator and then suggests the use of other, more specific diagnostic tools to further pinpoint or correct the problems. When the diagnostic tool recommends and executes a data intensive application as the further diagnostic tool, it automatically configures a controller of the process control network to collect the data needed for such a tool.

摘要： Example methods, apparatuses and systems to correlate candidate factors to a predicted fault in a process control system are disclosed. Techniques may include obtaining a value associated with a particular factor corresponding to a process, and predicting a fault based on the value. A set of candidate factors corresponding to the predicted fault may be determined, and a correlation between the predicted fault and at least one factor from the set may be displayed. Different sections of the display may respectively correspond to the predicted fault and to the at least one factor, and the correlation may be indicated by time aligning the different sections. Modifications to one displayed section may result in automatic modification of other sections to maintain the correlation. A user may select one or more candidate factors to be displayed, and may indicate a particular point of a particular section to obtain additional details.
