This lightweight, free utility is a lifesaver for assigning basic IP parameters, device names, and MAC addresses to Siemens field devices before your engineering software (like Step 7 or TIA Portal) takes over. Windows XP (32-Bit), Windows 7 (32-Bit and 64-Bit),
The Siemens Primary Setup Tool (PST) is a foundational software utility used by automation engineers to initialize Siemens network components. When commissioning plant equipment, devices often lack an IP address, making standard network communication impossible. The Primary Setup Tool resolves this by allowing users to assign IP addresses and network parameters directly via the MAC address.
After installation, you will find PST 4.2 under . | | Likely Cause | Suggested Fix |
: Ensure the application is running with administrative privileges to properly access network hardware.
