ABSTRACT:
In a method of monitoring the status of a machine and/or a process run on the machine a plurality of parameters (v) containing information about the status of the machine and/or the process is measured and stored. From a database (24) a corresponding plurality of stored reference values for the parameters are extracted according to a predetermined criteria, and the plurality of measured parameters are compared with the plurality of corresponding reference values for determining the status of the machine and/or the process. A corresponding system for automatic on-line monitoring includes at least one sensor for sensing a plurality of parameters (v) containing information about the status of the machine and/or of a process run on the machine. Extracting unit (22) are provided for extracting from a database (24) a corresponding plurality of stored reference values for said parameters according to predetermined criteria. A comparator compares the plurality of measured parameters with the plurality of corresponding reference values for determining the status of machine and/or process.
