EPLAN Preplanning enables you to save engineering data early in the preplanning process. This data can include actuators and sensors for a plant system, machine or building. You can import data from external tabular sources and also enter plant system or machine overviews and graphical process and instrumentation diagrams. This allows you to quickly generate initial data sheets or specifications for materials procurement. You can also access the data collected in EPLAN Preplanning to use in downstream planning phases in engineering.
