"Processes and apparatus for obtaining data representative of the operational performance of a device for process control.Control system for assessment of the operation of a control device used to control a process, and the process for data acquisition.Are obtained data sample (- L) of a control device (10, 11, 12, 16, 17) during use to control a process of material (13).Selected samples of these samples are stored representing the results of the operation of the device through parts of their characteristics.And the same are selectively combined to obtain an indication of the characteristics of the whole device.Selected samples of the sample data are used to obtain information on the parameters selected of the control device based on the characteristics of the device.
