BoardScope turns raw .brd files into an interactive diagnostic workspace — measure voltages, trace signals, annotate faults, and close repairs faster.
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.
Establish a direct wire connection to the hardware using an appropriate RS-232, RS-485, or USB programming link. Navigate into the or PLC Settings menu. Execute a Format PLC Memory or factory reset command.
Unlicensed unlock software forces communication commands into the PLC that the device is not designed to handle. This can cause memory corruption, causing the PLC to enter a permanent "STOP" or "ERROR" state that can only be fixed by replacing the physical hardware. 3. Voided Warranties and Support
If you can tell me the (e.g., DVP-14SS2, DVP-28SV) and the firmware version , I can suggest the most appropriate unlocking tool. Also, are you trying to unlock the project file or the PLC hardware itself? Delta PLC Password Settings by WPLSoft - Delta Electronics delta plc password unlock software new
Advanced Delta variants—including newer firmware iterations of the popular —support multi-level administrative restrictions. These levels can completely block reading functions, lock out communication ports, or permanently disable uploads to ensure proprietary logic remains safe. Technical Recovery Methods
Recent updates in the automation community have introduced tools designed to handle the latest firmware on the DVP-ES2 , EH3 , and SS2 series. 1. Delta PLC Password Tool 1.0 (2025/2026 Edition)
WPLSoft and ISPSoft, Delta’s primary programming environments, also support project-level passwords. These protect the project file stored on a PC rather than the PLC itself. Unlike PLC passwords, project passwords do not affect PLC operation if the original source code remains available. In the landscape of industrial automation, Delta Electronics
We have reviewed dozens of tools. Here are the three most cited "new" solutions currently circulating in automation forums. Disclaimer: Use these only on equipment you own or have permission to repair.
Prevents unauthorized users from copying the program from the PLC to a PC.
Limits access to the software file itself. Navigate into the or PLC Settings menu

Using third-party cracking software may void warranties or violate security policies. Always ensure you have the legal right to access the PLC program before proceeding.
Once the hash is extracted, the tool applies known rainbow tables or dictionary strategies to reverse the encryption. The success of this method depends heavily on the specific PLC model and its firmware revision.
If you need legitimate help regaining access to a Delta PLC you own or administer, here are lawful, safe steps you can follow:
BoardScope is built around the real workflow of board repair — not around theory.
Drag in any .brd file. BoardScope parses it instantly — components, nets, pads, and both board sides rendered with zoom and pan.
Use the Fault Tree to follow a guided symptom path. Search rails, trace signal paths, and use the Short Finder to locate bridges.
Record voltages per net directly in the app. Connect a serial multimeter for live readings with stable-reading detection and auto-fill.
Run the Test Suite to confirm every rail is back in spec. Export a pass/fail report and log the repair for the board model's history.
No switching apps. Everything lives inside BoardScope.
Connect real test equipment via USB — readings flow directly into the board view.
Download BoardScope and open your first board file in under a minute. No account required. Pro features unlock AI diagnosis, macro recorder, and test suites.
