摘要： 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 maintained On until communication between the field devices and the host computer is completed.

摘要： A control system uses a wireless mesh network to provide communication between a host computer and field devices. The host and the field devices communicate with one another using wireless messages containing requests and responses that are routed through the wireless mesh network. The wireless messages include sequence information that allow the receiving device to identify and reject messages that are received out of order.

摘要： 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 field device receiving the message will respond. The wireless network cycles between a sleep state and an active state based upon a wireless network power cycle. The predicted response time is based upon the current state of the wireless network, the power cycle, and the time required for the field device to turn on, take an action (such as measuring a parameter), and generating a response message.

摘要： 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 control messages to field devices using their field device addresses. The gateway translates the field device address of a control message to a wireless address of the wireless node with which the field device is associated. The gateway sends a wireless message over the network to the wireless node at the wireless address. The message contains the field device address so that, when the wireless message is received and opened, the control message from the host computer can be routed to the intended field device based upon the field device address.
