Licensing

• S7-SCL is an integral part of the STEP 7 Professional software package or is available as a stand-alone software product.
• S7-SCL V5.6 is delivered with a floating license. The floating license allows installation of the software on any number of computers. This means one user per license can use the software independently of the computer used or from a specific workstation. The number of existing licenses determines the number of computers on which the software can be used simultaneously.
• An upgrade to version 5.6 is offered for users of the previous version 5.3.
• A separate update service can be purchased for S7-SCL.
• A trial license valid for 21 days is available for download from Industry Online Support: https://support.industry.siemens.com/cs/document/109748118
