The aim of the invention is to better adapt the power range of a linear motor to specific applications. For this purpose, the secondary part () is subdivided into at least one first () and one second section () in the direction of travel () of the primary part (). The secondary part (), in the first section (), has a different shape than in the second section () and/or is produced from a different material. In this manner, different speeds of the primary part () can be achieved on the traveled distance independent of the actuation of the primary part. Optionally, cage windings can be inserted in a section of the secondary part so that said secondary part can be used for passive breaking.

The invention relates to a system and method for the control of a first station () in a switched data network () by a second station () in the switched data network (), the communication between stations of the switched data network () taking place via one or more point-to-point connections in transmission cycles which are synchronous with one another; for the transmission of a reference value from a first station () of a switched data network () to a second station () of the switched data network (), the communication between stations of the switched data network () taking place via one or more point-to-point connections in transmission cycles which are synchronous with one another; for the transmission of input values and output values between an input/output station () and a control unit () via a switched data network (); for the transmission of a data telegram with applications data via a switched data network (); and for the generation of a relative clock () in a station () of a switched data network ().
