    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: An adapter (300) for coupling to a process control transmitter (308) of the type used to monitor a process variable in an industrial process includes a first connection configured to couple to a first side of a two wire process control loop (302), a second connection configured to couple to a second side of the two wire process control loop (302) and in series with a first connection to a process control transmitter (308), and a third connection configured to couple to a second connection of the process control transmitter (308). Wireless communication circuitry is coupled to at least the third connection and is configured to provide wireless communication for the process control transmitter (308).

    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 translation: 无线网状网络由具有用于发送和接收消息的常规有效时间表的节点（GW1，GW2，AF，XZ）和当存在用于传输大量消息的需求时本地激活的快速有效时间表模式 。 当每个节点向另一节点传送消息时，传送节点包括消息缓冲器队列参数，该消息缓冲器队列参数指示传送节点中未决消息队列中的消息数量。 接收节点基于接收到的消息缓冲器队列参数和其自身的容量来确定是否继续按照常规调度，或者激活快速激活调度。 如果快速激活调度被激活，则接收节点向发送节点发回特殊的确认消息，使得两个节点将通过快速有效调度链路发送和接收消息，直到发送节点的消息缓冲器已经减少，并且 快速活动时间表可以停用，以支持常规活动时间表。
