In legacy Siemens ecosystems—primarily encompassing the platforms running under STEP 7 Classic (SIMATIC Manager)—protection levels are assigned to safeguard system blocks, functional blocks (FBs), and function calls (FCs). Protection Levels

For the S7-200 series, Siemens documents the "wipeout.exe" utility (found on the STEP 7-Micro/WIN installation CD or the ProDIS website) to restore the CPU to its default settings. Another documented method is to use the "wipeout.exe" program to clear the memory of the S7-200, which deletes the user program and the password. Additionally, the S7-200 has a universal clear password, "CLEARPLC", which, when used, will delete the program from the CPU. Another documented method is to use the "wipeout

When a password is lost, you generally have two paths: recovery (finding the code) or a full reset (wiping the CPU to start fresh). 1. Software Recovery Tools The "Search Password S7" program

Tools like "S7Key" work by accessing the memory where the password hash is stored. S7 300 - Reset PLC password - URGENT - Siemens SiePortal

Several similar third-party tools have been documented. The "Search Password S7" program, for instance, is described as a tool for finding passwords on S7-300 and S7-400 controllers where the program resides in the CPU's internal memory rather than on an MMC or MC flash card. Another example is a tool that gained notoriety for using a brute-force method—systematically trying every possible password combination—against Siemens S7 PLCs.
