Interception of the password hash via network packet sniffing during an authentication handshake.
Protecting intellectual property.
Moreover, within these systems, individual blocks (OBs, FBs, FCs, DBs) can be encrypted with "Know-How Protection" passwords. These secure the block's source code, allowing it to be used as a black box without revealing its internal logic. Without the password, even engineers with full CPU access cannot view the block's code.
