Abstract
A remote monitoring and control device or “remote device” generally for use in SCADA type environments. The remote device comprises a wireless IP type communication facility. The remote device further comprises a variety of communication channels, links, or ports for transmitting commands and receiving data to and from various instruments that may be connected with the remote device. Using the wireless IP communication facility, the remote device may provide a conduit for information and commands between the instruments and a central computer. In addition, the remote device may monitor the instruments and provide an unsolicited communication with the central computer when an abnormal value is detected at an instrument.

17. A method for transmitting information from a remote location to a central location in a SCADA environment, the method comprising:
-
monitoring one or more data parameters at the remote location;
determining if the one or more data parameters meets a value;
if the one or more parameters meets the value, generating at least one data packet indicative of the one or more data parameters meeting the value; and
wirelessly transmitting the at least one data packet to the central location. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
