摘要： A smart field-mounted control unit, for controlling a process, receives signals and sends a command output over a two-wire circuit which powers the control unit. An input section receives the signal, which can be instructions representative of commands or instructions sets, process variables sensed by external control units or setpoints representative of a desired process state. The instructions are representative of a control requirement of the process and adjust a controlling section in the control unit to generate the command output in conformance with the control requirement. The command output can be a function of the difference between the process setpoint and a process variable, or a function of a linear combination of a process variable and its calculated time integral and time derivative functions. A sensing section in the control unit can sense and scale a process variable for generating the command output as well, The control unit can include a regulator section, controlled by the command output, which regulates application of a mechanical, hydraulic, pneumatic or electromagnetic force applied to the process.

摘要： 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 when messages cannot be transmitted or received. Based upon messages to be sent by the host computer to selected field devices, the network is controlled to selectively maintain active those nodes required to route messages to the selected field devices. Those required nodes are maintained in an active state as long as communication with the selected field devices continues, while other nodes are allowed to return to a low power inactive state. When communication between the host computer and the selected field devices is no longer required, the entire network is allowed to enter the low power inactive state.

摘要： A wireless mesh network is formed by nodes 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.
