An electrosurgical generator system includes an electrical generator having an RF stage for outputting electrical energy having at least one waveform for performing an electrosurgical procedure. The system further includes at least one control module executable on at least one processor which controls at least one parameter of the outputted electrical energy and a configuration controller operably associated with the electrical generator which generates configuration data to configure the at least one control module to provide at least one modality of control of the outputted electrical energy based on the configuration data.
