• Welcome to the S7BlockProtectionManager homepage!


This tool was made to easy view and modify the “KNOW_HOW_PROTECT” protection on S7-300® and S7-400® blocks.

It is usable for OB, FB, FC and DB blocks
  • Your engineering office does no longer support the software they had developed.
    So you need to work with some S7 program blocks witch say "Block is protected" ?
  • You like to keep only one copy of every block ?
  • You lost your source code ?
  • You like to set and remove the "Know_How_Protect" protection simply, without compiling your blocks again?

If you are in one of these situations, the S7BlockProtectionManager will solve your problem!
