Recently Id been called by Hindalcos Fabrication Plant division to unlock the protected blocks in Siemens SIMATIC Step 7.

They were in need to unlock those blocks since an year because of 1 million Rupees of loss per month.

They want to re-program those blocks but it was locked by the man whod done the setup.

From the people working in that department, I came to know that they were trying to call that man (someone from Italy) right here but hes not coming.

Actually, what hed done was that hed locked some of the blocks and deleted the source file.

Department people also told me that even the people working in Siemens dont know how to do it.

Being a software engineer I know that any thing can be reverse engineered.

How did I unlocked the blocks The first thing Id done was searched about this software at Google and read about what is this software all about.

Further on hed shown me how do they lock a block via KNOWHOWPROTECT.

The blocks are now protected which means the code inside the block cant be seen by other.

So Id followed the steps given below to unlock those blocks, Step 1: Download.dbf file editor.
