Let’s walk through a typical recovery using a modern Delta PLC password unlocker.

Preparation:

Step 1: Wiring Connect pins 2 (RX), 3 (TX), and 5 (GND) from your converter to the Delta DVP’s COM1 port.

Step 2: Power Cycle Turn the PLC off for 10 seconds, then on. This resets the communication buffer.

Step 3: Software Configuration Open the new unlock tool. Select:

Step 4: The Attack Click “Start Unlock.” The new software will send a specific hex string %EE#1006... (a backdoor handshake). Within 2 to 20 seconds, the tool will display:

“PLC Password: 12345678 (Default) – Code Cleared”

Step 5: Verification Open WPLSoft or ISPSoft. Perform an “Upload” without entering a password. The program will appear.

Note: For AS series, you must use the “Ethernet Scan” feature of newer tools, as the RS232 backdoor is patched.

The "new" distinction is critical. Older unlocking tools (circa 2015-2019) relied on brute-force attacks over RS-232 serial ports. With a 9600 baud rate, testing a 10-character complex password could take 14 years.

"New" software (2022–2024) uses three modern approaches:
