Patent Number Title Of Patent Date Issued
7986968 Control of field device on low power wireless networks July 26, 2011
A control system uses a wireless network to provide communication between a host computer and field devices. The host and the field devices communicate with one another using control messages and response messages based upon a known control system protocol. The control and response m
7986657 Selective activation of field devices in low power wireless mesh networks July 26, 2011
A control system uses a wireless network to provided communication between a host computer and field devices. The field devices are normally maintained in a lower power or sleep state. Only field devices that will be involved in a communication with the host computer are turned On and
7924774 Control system with predictive field device response time over a wireless network April 12, 2011
A host computer communicates with field devices by sending control messages and receiving response messages over a wireless network. When the host computer sends a control message to the wireless network, the host computer is provided with a predictive response time within which the
7903596 Control of low power wireless networks for power conservation March 8, 2011
A wireless mesh network routes messages between a host computer and a plurality of field devices. The mesh network is synchronized to a global regular active schedule that defines active periods when messages can be transmitted or received by nodes of the network, and inactive periods
7783330 Control system with wireless address domain to field device address domain translation August 24, 2010
A host computer communicates with field devices over a wireless network that includes a gateway and a plurality of wireless nodes. At least one of the field devices is associated with each wireless node, and each field device has a unique field device address. The host computer sends
7768530 Verification of process variable transmitter August 3, 2010
A method and apparatus for verifying operation of process variable transmitters in process control or monitoring systems is provided. A process variable is measured with a process variable transmitter to verify operation of the process variable transmitter by comparing the process va
7600234 Method for launching applications October 6, 2009
An originating application in a process plant is able to launch multiple desired applications, with one or more of the desired applications having a different application programming interface. In one example, the originating application is able to launch multiple desired applications
5283716 Electrical component support structure February 1, 1994
A component support assembly releasably retains, electrically insulates and improves thermal transfer of a plurality of vertically stacked electrical components associated with the operation of a printed circuit card. Each of a plurality of integrally-molded component support structures
