: Contact the engineering firm that originally built the machine. They typically archive the original, uncompiled source code projects in their company repositories. To help find the right approach, tell me: What is the exact brand and model number of the PLC or HMI? Do you have a copy of the original backup project file ?

First, let’s address the elephant in the control room. | | | WinCC / TIA Portal |

It sounds obvious, but look through old server backups, printed electrical schematics, or the original vendor documentation. Often, commissioning engineers leave default passwords active (e.g., 1234 , 0000 , ADMIN ) or write the modified password inside the physical electrical cabinet panel.

Introducing unauthorized software into an industrial environment violates standard security frameworks like IEC 62443. Furthermore, if a third-party tool corrupts a controller driving heavy machinery, pumps, or chemical processes, it can cause severe physical damage, void equipment warranties, and create immediate safety hazards for plant personnel.

: Many HMIs, like those from Delta Electronics , have a factory default (e.g., 12345678 ) that is often never changed.
