    Abstract: A process variable transmitter (100) for use with a removable operator interface (202) has a non-volatile memory (204) and a latching component (210). The non-volatile memory (204) stores device settings (206). The latching component (210) prohibits changes to transmitter settings if the removable operator interface (202) is absent. Circuitry in the transmitter (100) detects the presence of the removable operator interface (202). The removable operator interface (202) can include zero and span settings.

    Abstract: A process variable transmitter (100) that preferably includes a transmitter output circuit (400, 300) that provides bidirectional HART and controller area network communication transceiver lines (LOOP+, LOOP-, CAN, GND). The transmitter output circuit also includes sensor circuit interface contacts (202) . An isolated circuit (201) couples to the sensor circuit interface contacts. The isolated circuit includes sensor circuitry sensing a process variable. The isolated circuit further comprises a galvanic isolation barrier (204) galvanically isolating the sensor circuitry from the HART and controller area network transceiver lines. A stacked power supply (Figs. 9A-9B) provides power management. Other aspects may include a controller area network current limiter diagnostic output (934), timed sequencing of microcontroller startup and shutdown, a local operator interface and power management.

    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.
