¿µ¹®³»¿ë¿ä¾à The standard defines interfaces for OCF-based interfacing of prosumer facilities among user-side electrical installations in the grid. The power generation, transmission, and distribution power facilities, which are the facilities of the power supplier, are managed by using standards such as IEC 61850 (Communication networks and systems for power utility automation). As it manages by itself, the degree of management of electric power facilities differs from customer¡¯s facilities. Small customer-side equipment such as prosumer equipment provides additional services for the safety management of equipment by providing a simple level of collection of status information using Modbus-based serial communication for reasons of equipment size and cost. This is a difficult situation. In addition, it is difficult to interwork between different manufacturers' facilities by defining and using Modbus data expression methods for each manufacturer. With the proliferation of IoT technology, development of standards and open source for connecting facilities such as homes, buildings, and factories, which are user areas using IoT-based OCF platforms, is actively progressing. However, electrical facilities are connected to IoT based on OCF. The work of providing it is still in its early stage. The standard defines interworking interfaces between Modbus data model and OCF data model for OCF-based connection of prosumer electrical equipment using Modbus data model.
