Report: SIMATIC STEP 7 V5.5 Professional Licensing SIMATIC STEP 7 V5.5 is a legacy engineering software used for configuring and programming SIMATIC S7-300 and S7-400 controllers. Licensing is mandatory for unrestricted operation, managed primarily through the Siemens Automation License Manager (ALM). 1. License Types for STEP 7 V5.5
Siemens provides several licensing models to fit different usage needs:
Floating License: The standard professional choice, allowing unlimited use on any one computer at a time or via a network.
Rental License: Valid for a specific operating time, typically 50 hours, which only elapses while the software is actively running.
Trial License: A free, one-time license provided with the software media, granting full functionality for 14 to 21 days for evaluation purposes.
Combo License: Found in newer versions (like TIA Portal V13+), these allow for the use of both the modern TIA Portal version and the "classic" STEP 7 V5.x versions. 2. Acquisition and Delivery
Since STEP 7 V5.5 is considered a "classic" version and has been largely replaced by newer versions like V5.7 or TIA Portal, official acquisition often involves: siemens simatic step7 v5 5 profesional license key
Upgrade Simatic Step7 V5.5 with Upgrade License - PLCTalk.net
This guide outlines the licensing and management of Siemens SIMATIC STEP 7 Professional V5.5, a core engineering software for SIMATIC S7-300 and S7-400 controllers. 1. License Types for STEP 7 V5.5 Professional
Siemens offers several license models to suit different engineering needs:
Floating License: Allows unlimited use on any one computer at a time and can be transferred between machines via a network or USB stick.
Rental License: Provides limited use for a specific duration as defined in the rental agreement.
Trial License: A 14-day or 21-day license for testing and validation.
Combo Floating License: Enables use of both classic STEP 7 (V5.x) and the newer TIA Portal versions.
50-Hour Trial License: A specific runtime-based license that only counts down while the software is actively open. 2. Professional Package Inclusions
The "Professional" edition differs from the standard version by including several high-level engineering tools within a single license: S7-GRAPH: For sequential function chart programming. S7-SCL: Structured Control Language (similar to Pascal).
S7-PLCSIM: Software for simulating PLC hardware on a PC without needing physical controllers. 3. Management via Automation License Manager (ALM)
The Automation License Manager is the mandatory tool for handling Siemens license keys. I can’t help with creating, finding, or distributing
Transfer: Licenses are typically delivered on a License USB Stick. To activate the software, you must use the ALM to "Cut and Paste" the license key from the media to the computer's hard drive.
Installation Prompt: During the STEP 7 setup process, the installer will check for a valid license. You can install it immediately from your media or skip and add it manually later via the ALM.
Unlicensed Mode: Without a valid key, STEP 7 will alert you every 10 minutes with a popup, and certain critical engineering functions may be disabled. 4. Upgrading to V5.5
If you are moving from an older version like V5.3 or V5.4, you must purchase an Upgrade License. Install the newer version of the software.
Transfer both the old license and the upgrade license to the same PC using ALM.
Use the "Upgrade" function within the ALM to merge them into a single, valid V5.5 license. STEP 7 Professional Licenses MLFB - Siemens SiePortal
Siemens AG actively pursues software piracy, especially in industrial markets. Using an unlicensed copy in a commercial production environment exposes your company to massive fines (up to $150,000 per instance in the US under the DMCA and EU Copyright Directive). Moreover, any automation-related injury or accident could lead to criminal negligence if unlicensed (and thus untested) software was used.
The "Professional" edition is critical because it includes the full suite: S7-SCL (Structured Control Language), S7-GRAPH (Sequential Function Charts), S7-HiGraph, and S7-PLCSIM (simulation software). The non-Professional or "Standard" license lacks these advanced languages.
It’s understandable: Step7 V5.5 Professional can cost over $5,000 USD for a single license. Many hobbyists, students, and even small integrators look for shortcuts. Web search results for "license key" often lead to:
Surprisingly, Siemens still sells Step7 V5.5 licenses, though it is officially in "phased-out support."
Note: Steps can vary. Follow Siemens-supplied activation instructions that come with your license. Purchase the software and license key directly from
