Techniques for assessing and presenting differences between the current commissioning data of a set of process control devices within a process plant and the respective baseline or defined commissioning parameters of the set of process control devices. According to embodiments, systems and methods may obtain the current commissioning data from the set of process control devices and access baseline parameters corresponding to the commissioning data. The systems and methods may compare the current commissioning data to the baseline parameters to determine a set of differences, and present, via a user interface, the set of differences for review by an administrator. In reviewing the set of differences, the administrator may facilitate different functionalities including rebaselining or reconfiguring process control devices.

A tandem control system for a machine tool, according to the present invention, comprises: a numerical control unit; a main operation unit; a PLC which executes a control command via communication with the numerical control unit or the main operation unit; a servo drive which includes a notch filter unit and executes the control command from the PLC; a servo motor unit which is driven under the control of the servo drive; and a power conversion unit which is electrically connected to the servo motor unit and the servo drive so as to apply current to the servo motor unit, wherein the servo drive suppresses resonance due to the operation of the servo motor unit by controlling the application state of current transferred to the power conversion unit according to changes of notch &; filter coefficients calculated in real time at the notch filter unit.
