Dear experts.

today i tried to do some modifications in one of our s7-1200 PLC and to my surprise the block was protected by know-how protection. i do not know the password for this block.

Is there any way that password is removed or I can make desired changes in my block?

Thanks in advance.

Hi,

the original password must be known to remove the protection again. Without the password, its not possible. At least as far as i know.

Hi Imameazam143,

You cannot remove know-how protection from a block without knowing the password. And while the block is protected, you cannot make any changes to it. So you should try to find out the password.

Kind regards
