SIMATIC STEP 7 is the professional engineering software developed by Siemens for configuring, programming, and commissioning their SIMATIC S7, C7, and WinAC automation systems. Before the TIA Portal era, STEP 7 Classic, including version V5.6, was the standard tool used for these tasks. It provides an Integrated Development Environment (IDE) known as the SIMATIC Manager. STEP 7 Professional V5.6 is essentially the same core software, offered as a bundle that may include additional optional packages.
Siemens protects Step 7 via the Automation License Manager (ALM). Licenses are transferred using specialized encrypted USB keys or via network license servers. License Types Simatic Step 7 V5 6 Sp2 Download
