Abstract: An application programming interface schema, method and system for communicating between first and second application programming interfaces within a process control system includes processing a call from a first application programming interface for a data request, translating the data request from the first application programming interface into one or more methods of a unified application programming interface, and implementing the one or more methods of the unified application programming interface with a second application programming interface. A first unified layer receives a transmission request from a proprietary application programming interface, and translates the transmission request into one or more methods of a unified application programming interface. A second unified layer implements methods of the unified application programming interface with the wireless network application programming interface.

Abstract: A method and system of communicating between a wireless network and a process control system communicatively coupled to a server, such as OPC. The server receives data from the wireless network, where the data is generated from an input/output data point within the wireless network. The server maps the data between the input/output data point and a data point placeholder within the process control system. The server writes the mapped data to the corresponding data point placeholder of the process control system via a process control interface, and the mapped data is provided to the process control system as process control data native to the process control system. Process control data may also be provided to the server, mapped between a data point placeholder of the process control system and an input/output data point of the wireless network, and written to the corresponding input/output data point.

Abstract: A method and system of communicating between a wireless network and a process control system communicatively coupled to a server via a process control system interface, such as OPC or a proprietary API. The wireless network may be a mesh network and the server may be a mesh server. The server receives data from the wireless network, where the data is generated from an input/output data point within the wireless network. The server maps the data between the input/output data point and a data point placeholder within the process control system. The server writes the mapped data to the corresponding data point placeholder of the process control system via the process control interface, and the mapped data is provided to the process control system as process control data native to the process control system. Process control data may also be provided to the server, mapped between a data point placeholder of the process control system and an input/output data point of the wireless network, and the mapped process control data is written to the corresponding input/output data point.

Abstract: Disclosed are methods and devices for controlling a process with a control signal. Iterations of a control routine are implemented to generate the control signal, and when an indication of a response to the control signal is unavailable, a feedback contribution to the control signal is maintained over one or more of the iterations of the control routine. The feedback contribution is then modified upon receiving the response indication, in which the feedback contribution is determined in accordance with an elapsed time between the received response indication and a previous communication of the response indication.

Abstract: A handheld communicator wirelessly interfaces or communicates with individual devices in a process control system, such as field devices, controllers, etc., to wirelessly perform monitoring, maintenance, configuration and control activities with respect to those devices. The wireless handheld communicator includes a housing adapted for handheld operation, a processing unit disposed within the housing, a computer readable memory disposed within the housing and coupled to the processing unit and a display, a keypad and a radio frequency transceiver. The handheld communicator may be adapted to communicate with a host system to receive information needed to communicate with various field devices in the process plant and may then be used to wirelessly communicate with each of the various field devices directly while in close proximity to the field devices to perform monitoring and configuration activities with respect to the field devices. Thereafter, information obtained from the field devices may be wirelessly communicated to the host system or to a repository, such as a data historian or a configuration database.

Abstract: A communication method operates to seamlessly transmit internet protocol (IP) data frames, such as IPv6 data frames, over a communication network that uses a non-IP network routing protocol, i.e., a communication network that implements a network routing protocol other than, or that is incompatible with an IP network routing protocol, such as the WirelessHART protocol. This communication method enables, for example, field devices or other intelligent devices within a process plant network that uses a non-IP communication network to perform messaging of IP data frames generated at or to be received by internet protocol enabled devices either within the process plant network or outside of the process plant network.

Abstract: Disclosed is a controller having a processor and a control module adapted for periodic execution by the processor and configured to be responsive to a process variable to generate a control signal for a process. An iteration of the periodic execution of the control module involves implementation of a routine configured to generate a representation of a process response to the control signal. The routine is further configured to maintain the representation over multiple iterations of the periodic execution of the control module and until an update of the process variable is available. In some cases, the update of the process variable is made available via wireless transmission of the process signal. In those and other cases, the controller may be included within a process control system having a field device to transmit the process signal indicative of the process variable non-periodically based on whether the process variable has changed by more than a predetermined threshold. In some embodiments, the field device also transmits the process signal if a refresh time has been exceeded since a last transmission.

Abstract: A first node sends a first message to a second node. The second node sends a second message to the first node. A first elapsed time is measured from the beginning of the transmission of the first message to the beginning of receipt of the second message. A second elapsed time is measured from the beginning of the receipt of the first message to the beginning of the transmission of the second message. The second node sends a third message to the first node containing the second elapsed time. The distance between the first and second node is calculated based on these elapsed times and a calibration count multiplier contained in the second or third message. A node may be moved within a wireless mesh network. Positional information about the node and distances to its neighbors is determined and transmitted to the network manager where it is stored.
