The Siemens Primary Setup Tool (PST) version 4.2 was a critical utility for assigning IP addresses and node names to SIMATIC NET Industrial Ethernet products. However, it is important to note that this software is largely legacy. Status and Downloads
Version Update: PST V4.2 was officially updated to V4.2 HF1 (Hotfix 1).
Official Successor: Siemens has replaced the Primary Setup Tool with SINEC PNI (Primary Network Initialization). For modern hardware and newer Windows operating systems, Siemens recommends using SINEC PNI Basic for commissioning tasks.
Official Download: You can find the legacy download for PST V4.2 (and the subsequent V4.2 HF1) on the Siemens Industry Online Support (SIOS) portal. Key Functionalities
Network Scanning: Scans for Siemens devices on the Industrial Ethernet network that have not yet been assigned an IP address.
Address Assignment: Allows the user to verify and modify network address data, such as IP addresses and node names, without needing a full installation of TIA Portal or STEP 7.
Quick Commissioning: Ideal for initial setup of devices like SCALANCE switches, PROFINET IO devices, and ET 200 distributed I/O. Security and Usage
Security Advisory: Legacy versions of PST have been cited in security advisories (such as ICSA-17-129-01) related to vulnerabilities in PROFINET discovery protocols. Siemens recommends updating to the latest available hotfixes or transitioning to SINEC PNI to ensure better security. Siemens Primary Setup Tool V4.2 Download -UPD-
Language Support: Upon first start, the tool allows you to select the interface language (e.g., German, English). Siemens devices using the PROFINET Discovery and ... - CISA
In the fast-paced world of industrial automation, the Siemens Primary Setup Tool (PST) acts as the "first handshake" between a computer and a new piece of hardware. Imagine a brand-new factory floor where dozens of SIMATIC NET components, like SCALANCE switches or Ethernet gateways, have just been unboxed. They have MAC addresses, but no way to talk to the rest of the network yet. The Role of PST V4.2
This is where Siemens Primary Setup Tool V4.2 steps in. Its primary mission is to assign initial IP addresses and names to these "blank" devices. Instead of requiring the massive overhead of the full TIA Portal, PST is a lightweight utility designed for one specific, critical task: initial commissioning.
Network Discovery: Using the DCP (Discovery Control Protocol), the tool "browses" the local network to find any unconfigured Siemens components.
Identification: It displays a tree view of MAC addresses. A technician simply matches the MAC address on the physical device's sticker to the one on the screen.
Configuration: Once identified, the user can type in a valid IP address and "download" it directly to the module. The Evolution: V4.2 and Beyond
Version 4.2 was a notable update that improved compatibility for SIMATIC NET Industrial Ethernet products. However, the story of PST is also one of transition:
Legacy Challenges: While versions like V4.2 were reliable for older systems, users often faced hurdles with modern operating systems like Windows 10, sometimes requiring a Windows 7 virtual machine to run properly.
The New Standard: Siemens has increasingly shifted users toward the SIMATIC Automation Tool and the TIA Selection Tool for managing multiple devices efficiently. Where to Download
Official downloads for Siemens software, including the PST and its updates, are hosted on the SiePortal (formerly Industry Online Support).
The Siemens Primary Setup Tool (PST) V4.2 is a specialized utility used to assign IP addresses and station names to SIMATIC NET network components. The Siemens Primary Setup Tool V4
Important Status Update: Siemens has officially discontinued the Primary Setup Tool. While older versions like V4.2 HF1 supported Windows 10, it is no longer actively available for download from the official Siemens Industry Online Support (SIOS) portal. Recommended Successors
Siemens recommends transitioning to the following modern tools which perform the same network initialization functions:
SINEC PNI Basic: The direct official successor for primary network initialization.
PRONETA: A free tool for commissioning and diagnostics of PROFINET networks.
SIMATIC Automation Tool: A more comprehensive tool for managing multiple devices, firmware updates, and IP assignments. Installation Guide for Legacy PST V4.2
If you already possess the installation files, follow these steps to set it up:
System Preparation: Ensure your PC is on the same physical network as the Siemens hardware. Note that PST V4.2 HF1 is compatible with Windows 10 Pro, Windows 7, and Windows 8.1.
Run Installer: Locate and double-click Setup.exe from your unpacked ZIP file.
Follow Setup Wizard: Follow the on-screen instructions until the final dialog confirms a successful installation.
Initial Launch: Open the tool via Start > SIMATIC > Primary Setup Tool. On the first run, you will be prompted to select your preferred language.
DCP/DLC Protocols: PST uses DCP and DLC protocols for communication. If you receive a "DLC protocol not installed" message, follow the prompted instructions to install it on your network adapter. IP Address Assignment Using Primary Setup Tool (PST) Siemens Download Manager (SDM)

Pro Tip for non-customers: Siemens offers a Time-limited demo version of PST V4.2 on their public GitLab or support forum. Search for "PST Demo - 21 day trial".
For cybersecurity-conscious plants, V4.2 introduces the option to set initial passwords and disable SNMP v1/v2 during first setup.
The Primary Setup Tool is a free utility from Siemens AG designed for the initial commissioning of SIMATIC PN (PROFINET) devices. Unlike TIA Portal or STEP 7, which are full-scale engineering platforms, PST is a lightweight, standalone tool focused on one core job: preparing devices before they are integrated into a broader automation project.
With PST V4.2, you can:
The keyword "UPD" in our title signals that this guide covers the latest maintenance release, which includes critical bug fixes and improved compatibility with modern Windows operating systems and newer Siemens hardware like the S7-1200 G2 and ET 200SP series.
You can now create a template in Excel, fill in IPs and device names, and import directly into PST. This is a game-changer when commissioning 100+ identical devices.
Before proceeding with the Siemens Primary Setup Tool V4.2 Download -UPD-, ensure your PC meets these requirements:
