Abstract

The present invention is a remote monitoring diagnostic system and method for centralized monitoring of multiple industrial plants. The remote monitoring system comprises a data storage file used to collect and store plant data representing operation status of the plant, a monitoring system to monitor the plant according to the collected plant data, a database storing the past plant data associated with errors having occurred at the plant and actions taken to cope with the errors, a diagnostic system to analyze the plant data sent according to the database, and a reporting system to send a report to the user of the plant regarding the causes for the error and/or actions taken to cope with the error based on the result of the analysis.
