Explain the GSD file in the TIA portal
These are files that are supplied by other parties to be seized via Siemens TIA. Think of controlling a frequency regulator. You get the function blocks needed for control. GSD file has got nothing to do with TIA, in fact, every device which communicates on Profibus needs a GSD file, and bear in mind Profibus is an open platform not only for siemens. simply put a GSD file is a text file that describes your device for it to be configured on Profibus DP
