Siemens or external system. GSDML Device master file This file is required to be able to configure a device as a DN device in the HW Config of a Siemens or external system. Hardware support package The hardware support packages allow you to configure modules that are not listed in the hardware catalog of your TIA Portal installation.
Page 360 The soft starter can be configured with the STS (Simulation Tool for Soft Starters) software. The STS suggests suitable soft starters for the application based on the motor and load data and application requirements that you enter.
