Do you need a new licence or an extension?
We will match the order number to your project, your existing licence and your preferred delivery method.

Software usage
Select this for supported projects with the S7-1500F, S7-300F, S7-400F, fail-safe Software Controller or WinAC F. It is also suitable for the S7-1200F. Please check the specific CPU, firmware and any other options required for your project. Following any changes to the safety programme, it is essential to carry out the appropriate checks and verification of safety functions.

Full Licence and Upgrade Combo
The Upgrade Combo is intended for the corresponding existing Distributed Safety V5.4 or Safety Advanced V11-V20 Combo. It enables the licence-restricted parallel use of Distributed Safety V5.4 SP5, Safety Advanced V11-V20 and V21. This ‘Combo’ designation relates to safety software; it does not replace the selection of a basic STEP 7 licence.

Scope of delivery and licence management
For these variants, the delivery of the licence key is the key factor. The key itself does not imply that the package also includes the new STEP 7 base environment. We will verify the availability of installation files and the required base software based on the selected code.
For electronic delivery, we require the recipient’s email address. Before reinstalling or replacing a hard drive, ensure that licence keys are transferred securely; do not consider simply copying files to be a confirmed licence transfer.
Project and computer compatibility
Please send us the project version, the exact CPU or HMI type, the firmware, and the edition and version of Windows. Together, we will check the configuration in Siemens Compatibility Tool. A licence for a newer version does not in itself guarantee that every older project can be opened.
Frequently asked questions
Is STEP 7 Basic V21 enough?
Safety Advanced V21 requires STEP 7 Professional V21. The inclusion of Safety Basic in a lower edition does not fulfil this requirement.
When should you choose the Combo upgrade?
If you own a corresponding older Distributed Safety or Safety Advanced Combo licence. For a new installation without such a licence, select a full licence.
Does the delivery include new PLC hardware?
The options listed are software licences. PLCs and associated hardware must be purchased separately.
