If you found a "top" result on a third-party file-hosting site (not siemens.com), proceed with caution. Downloading legacy industrial software from unverified sources poses a security risk (viruses, trojans) and may result in corrupted files that could misconfigure industrial hardware. Summary Siemens PST v4.2 is no longer available for public download. For modern devices, use TIA Portal or the device's web interface. For legacy maintenance, contact Siemens Support to obtain a copy of the archived software or locate your company's internal backup of the Service Pack DVDs.
