Abstract: A process control system includes at least one controller and at least one wireless valve element capable of being controlled by the at least one controller. The process control system also includes a first transceiver configured to communicate with the at least one wireless valve element and a second transceiver configured to communicate wirelessly with the first transceiver. The second transceiver is further configured to communicate with the at least one controller.

Abstract: A system for tracking an object associated with a mobile tag reader includes a first identification tag capable of providing a first set of location information associated with the first identification tag. The system also includes a second identification tag capable of providing a second set of location information associated with the first identification tag. In addition, the system includes a controller capable of correlating the first set of location information and the second set of location information to predict a current location of the object.

Abstract: A diagnostic concentrator includes a first interface that is capable of receiving a signal sent from a field device to a process controller. The signal includes a primary process variable and additional information. The diagnostic concentrator also includes a controller that is capable of generating a message corresponding to the received additional information and a second interface that is capable of transmitting the generated message. The first interface may be a HART interface. The second interface may be a wireless interface or a network interface. The message may be transmitted to a diagnostic monitor or a process controller. The first interface may receive a plurality of signals sent from a plurality of field devices to the process controller. The controller may generate a plurality of messages corresponding to the plurality of additional information in the signals and transmit the messages via the second interface.

Abstract: Methods, devices and systems for integrating multiple communication systems including multiple wireless communication protocols into a single system are discussed. In an illustrative example, a communication system includes a device adapted to communicate via first and second wireless communication protocols. The system may further include local area network or other wired sub-network, with the device adapted for first and second protocols also being adapted to operate using the local area network or other wired sub-network.

Abstract: Methods and devices for operating a wireless network including redundant communication. Methods involving redundantly connected nodes are discussed including addressing methods and/or methods of creating groups for such redundant communication. The use of primary and secondary redundant connections is discussed. The inclusion of a redundant network in association with a non-redundant network such as a Zigbee® protocol network is discussed. Also, devices for implementing such methods are described.
