  • Vacuum system central control information server
    Patent number: 7016751
    Abstract: Status information about the vacuum system is received by a server. A portion of the status information is formatted in response to a request from a web browser, and the formatted vacuum system information is forwarded to the web browser. Commands, including parameter values, can are entered by a user from the web browser, and implemented at the server or forwarded to the proper component in the vacuum system. A command or change history log of commands is maintained and forwarded to the web browser upon a request from the web browser. Status information includes information about an on-going regeneration of a pump in the vacuum system. Furthermore, regeneration can be controlled, i.e., started, stopped, parameters adjusted, in response to commands received from the web browser. Plural sets of regeneration parameters can be defined by a user from the web browser, and issued simultaneously to many devices.
