DIN EN IEC 63376:2024-06

This document specifies the functions and the information flows of industrial FEMS (Facility Energy Management System). These industrial energy management systems are referred to as FEMS (Facility Energy Management Systems). Generic functions are defined for the FEMS, to enable upgrading traditional EMS (Energy Management System) from visualization of the status of energy consumption to automating energy management defining a closer relation with other management and control systems. A generic method to classify the FEMS functions will be explained. The information exchange between the FEMS and other systems such as MOM (Manufacturing Operations Management), (MES (Manufacturing Execution System)) and ERP (Enterprise Resource Planning) will be outlined. This standard models data on energy use by equipment in factories and plants and specifies data exchange to enable the distribution of information on energy use in processes in factories and plants. In addition to optimizing energy efficiency as individual equipment, FEMS also enables coordinated control between multiple pieces of equipment at different locations. This document does not specify concrete parameters or variables for energy management systems, nor does it describe algorithms for energy optimization. The document identifies further limitations of the scope, particularly in relation to other enterprise control systems, such as enterprise resource planning (ERP) and manufacturing execution systems (MOM/MES). The optimal operation of an industrial facility requires coordination between affiliated organizations. Therefore, the functions of an industrial energy management system (FEMS) for a facility shall be standardized in order to realize the benefits of better use of available energy and between companies and organizations. Manufacturing systems are subject to various constraints for general optimization, such as safety, cost, product quality, production schedule, market requirements, and other constraints specific to the industry and application. These various constraints are prioritized according to the business situation and used as target functions for optimization. Due to the complexity and continuous availability of practical operating conditions, the target functions for optimization are in most cases set manually on the production system by an experienced technician or operator with comprehensive knowledge of the operation. The FEMS can support these individuals by providing the necessary information for their decision-making process during operation. The FEMS provides the necessary functions and information for the aforementioned optimization.
