Abstract: A system and method are provided for the combined acquisition of data for SCADA and simulation or network calculation applications. At least one data processing device has means for generating templates and acquiring data. The means allows at least two model levels of a supply network (e.g., a gas network) to be generated on the basis of a template and/or pattern in cooperation with at least one data memory. At least one consistent generic template contains a uniform, consistent pattern for a detailed model of at least one first model level, for a simplified model of at least one second model level, and/or respective conversion instructions, such as for the transition between at least two respective model levels, to be established and/or retrieved for recurring subareas and/or object groups and/or objects of the at least two model levels.
