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. The vacuum system status information is be compared against one or more alarm definitions to determine whether an alarm exists, i.e., is 'active.' Active alarms are sent to the web browser. Furthermore, a historical log of alarms is maintained and a portion of it forwarded to the web browser upon a request for alarm history. Alarms may be enabled or disabled individually by means provided to the browser. Means are provided to the browser to allow a user to specify alarm definitions.
