ABSTRACT:
A system and method for computer control of machine processes. The system and method provide a set of predefined data management or data analysis tasks which an operator of the system can use when using the system to run a selected process.
Measurement data structures for storing data measured during the running of processes, and related data, for a multiplicity of processes are defined and stored. Data is added to these data structures each time a process is run, and this data is automatically accessed when the operator requests data analysis on the data collected during previous uses of a selected process.
Access to measurement data for detailed data management tasks is provided graphically through the use of trend charts and statistical quality control charts. These charts depict trends in the measurement data for selected processes. By pointing at any data point in the chart, the user can access the corresponding record of data for detailed data analysis or for use in a data management task.
