Overview
What is TIA Portal?
TIA Portal (Totally Integrated Automation Portal) is Siemens's integrated engineering environment that combines PLC programming (STEP 7), HMI configuration (WinCC), drive parameterisation (STARTER/Startdrive), and motion control in a single application. It replaced the older STEP 7 Classic (SIMATIC Manager) for new projects starting around 2012.
The current hardware families programmed in TIA Portal are the S7-1200 (compact, cost-effective, IEC 61131-3 native), S7-1500 (high-performance, safety variants available), and S7-300/400 (legacy but still extensively installed). TIA Portal supports all five IEC 61131-3 languages: Ladder Diagram (LAD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL, deprecated in newer versions), and Sequential Function Chart (SFC/GRAPH).
Licensing
TIA Portal license tiers
All pricing should be verified directly with Siemens or an authorised distributor — prices vary by region and change over time.

| STEP 7 Professional | S7-300/400/1200/1500 + all languages | Yes (Standard) | Check vendor for current pricing |
| STEP 7 Professional + PLCSIM Adv. | As above + real-time simulation, OPC UA | PLCSIM Advanced (add-on) | Check vendor for current pricing |
| Academic license | Professional features — subsidised | Yes | Apply via Siemens Academic Program |
Requirements
TIA Portal system requirements
TIA Portal is one of the most resource-intensive PLC IDEs available. Requirements below are for current V18/V19 — always verify against the Siemens SIOS release notes for your specific version.
Download steps
How to download the TIA Portal 21-day trial
Create a Siemens ID account
Go to siemens.com and create a free Siemens ID account. This is Siemens's unified login for the Industry Online Support portal, Software Delivery Portal, and license management. You need an email address and a Siemens ID to download any TIA Portal package.
Go to the Siemens Software Delivery Portal
Navigate to the Siemens Software Delivery Portal (support.industry.siemens.com/cs/document/109784440). Search for "TIA Portal Trial" or navigate through the STEP 7 category. Select the most recent version and your preferred download format (DVDs ISO or executable package).
Download the trial package
The full TIA Portal trial download is large — typically 15–25 GB for Professional + WinCC + PLCSIM. Use a download manager or the Siemens Download Manager tool to avoid interrupted downloads. Allow several hours on a typical broadband connection.
Run the installer as Administrator
Extract the downloaded package and run the start centre as Administrator. Select the components you want: at minimum STEP 7 Professional and PLCSIM. WinCC Basic is useful if you are also learning HMI. The installer handles all dependencies including .NET and SQL Server LocalDB.
License activates automatically for 21 days
The trial license installs automatically during setup. You do not need a separate license key for the trial — the 21-day clock starts on first launch. After 21 days, TIA Portal reverts to a feature-limited mode until you activate a paid license. Save your work frequently near the end of the trial.
Practice now
Practice Siemens ladder logic in your browser while your download finishes
The TIA Portal download is large and installation takes time. Our browser simulator lets you start building Siemens ladder logic fluency immediately — using the same Normally Open / Normally Closed / Set / Reset / TON / TOF / CTU terminology that TIA Portal uses. No 21-day clock, no Windows required.
