Delta Plc Password Unlock Software New [better] Access
DVP-SS2
Unlocking a Delta PLC password typically involves either using specific recovery software for project files or specialized "crack" tools for the hardware itself. For newer Delta PLC series like the , ES2 , or EH3 , hardware-level security is more robust, often requiring professional services or specialized toolkits to extract data directly from the internal IC. 1.

Introduction
In the landscape of industrial automation, Delta Electronics is a dominant force, providing reliable Programmable Logic Controllers (PLCs) for a wide range of applications. As security becomes a growing concern in operational technology (OT), engineers frequently implement password protection on these controllers to safeguard proprietary logic and prevent unauthorized tampering. DVP-SS2 Unlocking a Delta PLC password typically involves
WPLSoft Procedure
: Open the WPLSoft software, navigate to Communication > Setup PLC program memory , and select Back to factory setting . This action erases both the password and the program. Power Down the PLC
- Power Down the PLC. Wait 60 seconds for capacitors to drain. This is crucial for the new "cold boot attack" method to work.
- Set the PLC to STOP mode. Move the physical switch to "STOP."
- Connect the hardware. Plug your USB-422 converter into the PLC's COM1 or COM2 port. Do not use the HMI port.
- Launch the software. Open PLCGuard Pro. Select "Delta -> DVP Series -> New Exploit 2024."
- Select Baud Rate. The software will auto-detect (usually 115200 or 38400).
- Click "Extract Hash." The tool will send a "warm start" command. The PLC will flicker its ERROR light once. This indicates the bootloader vulnerability is present.
- Click "Decode." The software uses a local rainbow table.
- Result: Within 15 seconds, the password appears on screen (e.g.,
*TechCorp#2021). - Connect WPLSoft or ISPSoft. Use the recovered password to upload the program and disable the lock permanently.
Yes, but with extreme caution.
