Abstract: A drivetrain for linear movement of a machine component along a linear guide of a machine includes a motor with a motor-measuring system. A length-measuring system is assigned to the linear guide for determining a position of the machine component. To determine rigidity of the drivetrain, a constant acceleration for the machine component is predetermined by a numerical controller for performing closed-loop control of the movement of the machine component. The numerical controller determines a difference between a position of the machine component derived from the motor-measuring system and a position of the machine component measured at the same time by the length-measuring system during the acceleration phase, and the difference is assigned to the acceleration or to a force required for the acceleration and storage in the numerical controller of the pair of values established in this way and/or of a rigidity value emanating from the pair of values.

Abstract: A method for redundant transmission of data telegrams between automation devices of an installation by a communication network requires a ring topology. A sending device sends out two data telegrams in different transmission directions of the communication network and a receiving device processes the data telegram arriving at the receiving device first and discards the other data telegram as a duplicate.

A network component arranged between the sending device and the receiving device receives the data telegram, recognizes the priority level based on the communication protocol used, and forwards the data telegram taking into consideration the priority level.
