Step 1: Isolate the Device Remove the PLC/HMI from the running machine network. Place it on a bench with a sacrificial laptop (no connection to your factory network).
Step 2: Full Backup (If possible) Even if locked, can you upload the raw binary? Use the official software's "Upload" function. Just because you can't open the file doesn't mean you can't save the binary to disk. Save it three times.
Step 3: Search by Exact Model Do not search "All unlock tool." Search "Password remove [Exact Model Number] [Year]."
Step 4: Use Sandboxing Run any downloaded tool in a Windows Sandbox or a VM (VirtualBox) that has no internet access and no shared folders.
Step 5: The Hex Editor Method (Most Reliable) Learn to use HxD (Free). For many HMIs (Weintek, Beijer, older Red Lion), the password is stored in plain text or simple XOR in the *.pbu or *.cdf backup file. You can literally search for the string "Password" in the hex view and see the value next to it.
