## Abstract

A computer implemented method at an energy management system (EMS) controller apparatus for automatic generation of a SCADA (supervisory control and data acquisition) slave interface for an energy management system (EMS), includes storing a SCADA configuration file mapping SCADA data points to EMS data objects; providing the EMS data objects coded in statically typed programming language; providing site configuration information of the energy management system (EMS); scanning, by an object access framework (OAF), EMS data objects with EMS annotations and combining them with the site configuration information to generate an object binding repository (OBR); and compiling the SCADA configuration file to combine the SCADA data points mapping with the object binding repository to generate SCADA bindings information as part of the SCADA slave interface for the energy management system (EMS).
