These mostly cannot be mapped into existing IT-Systems, since integration according to the idea of Plug and Play is not possible. To reach interoperability between the levels of field devices and control technology, an increasing amount of new standards and norms are being developed. OFFIS contributes actively to the international and national standardization, for example to the IEC or the German VDE/DKE and implemented together with CISE (Center for IT Standards in the Energy Sector) a competence center for automation and power system management, which offers the training of standards, consulting for the implementation in projects and decision support at the manufacturers, energy suppliers and the consultants.
