Siemens Primary Setup Tool 4.2 ((top)) Download (2026)

If you are looking for the Siemens Primary Setup Tool (PST) 4.2, you should know that Siemens has largely phased out this tool in favor of more modern successors. While version 4.2 (+ HF1) is the final iteration compatible with modern systems like Windows 10 (64-bit), finding an official standalone download link can be difficult as Siemens now directs users toward updated software. What is the Primary Setup Tool (PST)?

The PST is a utility used to assign initial network parameters (like IP addresses, subnet masks, and device names) to SIMATIC NET network components, Ethernet CPs, and gateways. It uses the DCP (Discovery Control Protocol) to find devices on a local network, even if they don't have an IP address yet. How to Get PST 4.2

Because there is no longer a direct, permanent public download link for the legacy PST on the main Siemens SiePortal, you generally have three options:

Check Your Product Media: The PST is traditionally supplied on the CD/DVD that comes with hardware like Scalance switches or ET 200 modules.

Request from Support: If you specifically need version 4.2 for a legacy system, you can open a Support Request with Siemens to obtain the file.

Use Existing Engineering Software: If you have STEP 7 or TIA Portal installed, you already have these capabilities. Use the "Edit Ethernet Node" function (found under the PLC menu) to perform the exact same IP and name assignments. Official Successors

Siemens recommends moving to these free, modern alternatives which offer more features and better security:

SINEC PNI Basic: This is the official successor to the PST. It is designed for initializing Siemens network components and can be downloaded from the Siemens Industry Online Support (SIOS) site. siemens primary setup tool 4.2 download

PRONETA Basic: A popular and free diagnostic tool for PROFINET networks. It can change IP addresses, names, and even perform I/O tests. You can find it on the PRONETA download page.

SIMATIC Automation Tool: Useful for managing multiple devices simultaneously, including firmware updates and IP assignments. Key Technical Details for PST 4.2

Step 3: Assign a Profinet Device Name (Crucial for PLC Communication)

For a device to be used as a Profinet IO device, it must have a name.

1. Select the device.
2. Go to Edit > Assign Name.
3. Type the exact name you defined in your TIA Portal or STEP 7 hardware configuration (e.g., ET200SP_Station_1).
4. Click "Assign Name."

The device will now respond to that name. If you later ping the device name via Windows Command Prompt, PST ensures your PC’s DNS is bypassed using DCP.

1. Initial Scan

• Open PST and select your network interface card (NIC) from the dropdown list
• Click "Search" or press F5
• PST will send DCP (Discovery and Configuration Protocol) broadcasts
• All found devices appear in a table with MAC addresses, current IP (if any), and device type

"No devices found" during scan

• Cause: Firewall blocking DCP (UDP ports 34964, 34980)
• Solution: Disable Windows Firewall temporarily or add PST to allowed apps
• Also check: Use a direct Ethernet cable, not Wi-Fi (DCP is link-layer, not routable)

Key Features of PST 4.2

Before we dive into the Siemens Primary Setup Tool 4.2 download process, let’s review the features that make this version a staple in the industry:
