    Abstract: A wireless mesh network is formed by nodes (GW1, GW2, A-F, X-Z) having a regular active schedule for transmitting and receiving messages, and a fast active schedule mode that is locally activated when a demand exists for transmission of a larger number of messages. As each node transmits a message to another node, the transmitting node includes a message buffer queue parameter that indicates the number of messages in the transmitting nodes, pending message queue. The receiving node determines, based upon the message buffer queue parameter received and its own capacity, whether to continue on the regular schedule, or to activate the fast active schedule. If the fast active schedule is activated, the receiving node sends a special acknowledge message back to the sending node, so that both nodes will transmit and receive messages over a fast active schedule link until the message buffer of the sending node has been reduced and the fast active schedule can be deactivated in favor of the regular active schedule.

    Abstract: A pressure measurement device (100) comprising an absolute pressure sensor (104) and a bus (114) coupling serial communication and energization to an electrical connector (110) in a field wiring compartment (108). An atmospheric pressure sensor module (116) is connected to the bus at the electrical connector. The bus provides the energization to the atmospheric pressure sensor module and the bus receives a serial communication signal from the atmospheric pressure sensor module. The serial communication signal includes numeric data (120) representing atmospheric pressure. The pressure measurement device provides a gage pressure output (124) as a calculated difference between the sensed absolute pressure and the received numeric data.

    Abstract: A process variable transmitter (200) connects a serial bus (232) to an accessory load. A supply limiter circuit (234) provides a first supply current limit and provides a stored energy output (236). A recessive driver circuit (238) draws a drive current from the stored energy output (236) and couples the drive current to the serial bus (232). The recessive driver circuit (238) provides a drive current limit. A dominant driver circuit (242) has a dominant state in which it conducts the drive current, and an inactive state in which the drive current is available to the accessory load.

    Abstract: An industrial process control transmitter (10) has a modular construction, with a detector module (16) and an output module (18) electrically connected together by a serial bus (20). The output module (18) includes a microcomputer (40), a modem (44) for digital communication over the two-wire loop, analog output circuitry (46) for controlling loop current, a digital-to-analog converter (48), and a memory (50) for storing calibration factors and D/A characterization factors. The detector module (16) includes several sensors (24, 28, 34) with associated circuitry (26, 32, 36) to convert the sensor signals to digital signals. The detector module (16) also includes a memory (38) which contains characterization factors unique to the sensors (24, 28, 34) which can be used by the microcomputer (40) to correct the digital values provided by the detector circuitry (26, 32, 36).
