Title:
電力節約のための低電力無線ネットワークの制御
Document Type and Number:
Japanese Patent JP5405123
Kind Code:
B2
Abstract:
A control system uses a wireless network to provide communication between a host computer and field devices. The host and the field devices communicate with one another using control messages and response messages based upon a known control system protocol. The control and response messages are embedded as a payload within a wireless message that is transmitted over the wireless network. When the wireless message is received at its ultimate destination, the control or response message is separated from the wireless message and is delivered to the intended recipient (either a field device or the host computer).
