CONTROL SYSTEM WITH PREDICTED RESPONSE TIME OF FIELD DEVICE VIA WIRELESS NETWORK |
摘要 |
FIELD: information technology. ^ SUBSTANCE: host computer communicates with field devices by means of sending control messages and receiving response messages via wireless network. When host computer sends control message via wireless network the host computer is given predicted response time within which a field device receiving the message should respond. Wireless network cycles between wait status and active status based on wireless network "current source connected/current source disconnected" cycle. Predicted response time is based on current status of wireless network, "current source connected/current source disconnected" cycle, and time of field device on, execution of action (like parameter measurement) and output of response messages. ^ EFFECT: providing possibility to determine if there was breakdown in connection with one of field devices when communicating via wireless network. ^ 13 cl, 6 dwg |
