Fatek provides software tools for programming and troubleshooting their PLCs. Sometimes, these tools can help in recovering or resetting passwords. The availability and capabilities of these tools can vary, so you might need to contact Fatek support or an authorized distributor for guidance.
Warning: This deletes everything. If you do not have a .fds or .prj backup file, you have a useless brick.
In the world of industrial automation, Fatek PLCs (FBs, B1, and FBe series) are renowned for their cost-effectiveness and reliability in factories, water treatment plants, and conveyor systems. However, there is a silent crisis that plagues maintenance engineers and plant managers: the lost or forgotten PLC password.
When a programmer sets a password on a Fatek PLC to protect intellectual property, and that person leaves the company or the documentation is lost, the machine becomes a digital brick. Without the password, you cannot upload the ladder logic (the program), modify timers, or even perform basic diagnostics. This leads to weeks of downtime, expensive rewrites of code, or scrapping entire control panels.
Searching online for a "Fatek PLC password crack fix" yields a minefield of malware-ridden software, unethical hacking forums, and contradictory advice. This article aims to separate fact from fiction. We will explore why passwords lock, legitimate recovery methods, and the engineering "fix" for a locked PLC.
A legitimate hardware crack does not "break encryption." Instead, it uses a side-channel attack:
The problem: For PLCs manufactured after 2020, Fatek patched this vulnerability. Reading R 3839 returns zeros if a password is set. For these units, the "crack" fails completely.
You are standing in front of a humming control cabinet. A critical production line is down. On your laptop screen, the FATEK WinProladder software stares back at you with a single, maddening dialog box: "Password Protected. Please enter Password."
The original machine builder went out of business three years ago. The lead electrician who set the password retired to Florida and isn't answering his phone. You have the physical PLC (Programmable Logic Controller), but the digital key is lost.
When technicians search for a "Fatek PLC password crack," they aren't necessarily looking for malicious hacking. They are looking for a fix—a legitimate, technical workaround to restore access to a machine they are responsible for maintaining.
In this long-form guide, we will explore what the FATEK security model looks like, why simple "cracking" is rarely possible, and the legitimate fixes available to recover or reset your FATEK PLC (specifically FBs and B1 series).
In the context of Fatek PLCs (such as the FBs series), "password crack" usually refers to bypassing restricted access to project files or the PLC hardware itself to recover or overwrite ladder logic.
If you have forgotten the password and cannot access the PLC, the standard "fix" depends on whether you need to preserve the data restore hardware functionality 1. Hard Reset (Data Loss)
If you do not need the program currently stored on the PLC, you can perform a factory reset. This clears all protected logic and the password. MMC Card Method : Create a new, blank project in WinProladder . Transfer this program to an MMC card.
: Power off the PLC, insert the MMC card, and power it back on. The PLC will copy the new, unprotected program from the card, overwriting the previous password-protected program. 2. Communication Vulnerabilities (Historical)
Legacy PLC firmware often had vulnerabilities that allowed password retrieval via serial communication. Vulnerability Mechanism
: Certain older models were susceptible to specially crafted serial commands that forced the PLC to return its password information in plaintext. Security Fix
: Fatek and other manufacturers have released firmware updates to patch these "plaintext" responses. To secure your PLC against such "cracks," you should update the firmware to the latest version. 株式会社ジェイテクトエレクトロニクス 3. "Password Show 5%" Error
Users often encounter a specific "5%" indicator in Fatek software when attempting to unlock a PLC.
: If the screen displays "5%" while asking for a password, it often indicates a deep protection level or corruption that typically cannot be bypassed through standard software prompts. Resolution
: In these cases, the "fix" is usually a complete program wipe via the MMC method mentioned above. 4. Third-Party Software Risks
Many "PLC Password Cracker" tools found online are known vectors for malware, such as the SecurityWeek fatek plc password crack fix
: These tools may steal cryptocurrency, block antivirus updates, or compromise the host PC used for industrial programming. Safe Alternative : For legitimate recovery of commercial projects, contact Fatek Support or use official distributors. Summary of Result To "fix" a locked Fatek PLC, you must either factory reset the unit using an MMC card (which deletes the program) or update the firmware
to prevent unauthorized password retrieval by others using legacy exploits. Avoid third-party "crack" utilities as they frequently contain malware.
If you have forgotten the password for a Fatek PLC, there is no official "backdoor" or "fix" to reveal the password without potentially losing the existing program
. Standard industrial security protocols are designed to protect proprietary ladder logic, so procedures generally focus on resetting the hardware to a factory state. Method 1: Factory Reset via MMC/Memory Pack
If you do not need to keep the existing program and just want to reuse the PLC, you can overwrite the internal memory using an external Fatek Memory Pack (MMC). Prepare a Blank Program: Winproladder
on your PC to create a new, empty project with no password protection. Download to MMC:
Transfer this empty project to a Fatek Memory Pack (e.g., FBs-PACK). Transfer to PLC: Power off the PLC. Insert the Memory Pack into the PLC's expansion slot.
Power the PLC back on. The system will automatically copy the project from the Pack to the internal RAM, overwriting the locked program and removing the password.
Power off, remove the Pack, and power the PLC back on. It should now be in a default, unprotected state. Method 2: Official "Forget Password" Feature
Fatek provides a member-based password recovery for their software portal, but this typically applies to your user account rather than individual PLC hardware units. Visit the official FATEK Forget Password page if you have lost access to your developer account. FATEK Automation Method 3: Check Default Credentials
In some instances, security examples or default setups use common placeholders. While Fatek PLCs do not have a universal default hardware password like some other brands, it is worth testing:
(Case-sensitive) is frequently used in official security examples. Fatek Polska Important Security & Technical Notes Irretrievable Data:
If a PLC shows a "5%" progress bar or specific lock message when requesting a password, it often indicates a level of protection that cannot be bypassed without a complete memory wipe. Third-Party Tools:
You may find "unlocker" software online (e.g., for FBs Series V5.83). Use these with extreme caution as they are unofficial, may contain malware, or could permanently corrupt the PLC firmware. Backup Importance:
Always maintain a copy of the project file (.fbp) on a secure drive. Once a program is downloaded to the PLC with a password, it cannot be "cracked" back into a readable file if the original source is lost. Security User Example Version: 1.1
If you have forgotten the password for a Fatek PLC or are concerned about security vulnerabilities that allow "cracking," the solution depends on whether you are trying to recover access or prevent unauthorized entry. 1. Recovering a Forgotten Password
Official Fatek documentation and industry standards emphasize that there is no "master password" or built-in backdoor for standard users.
Official Support: The most secure method is to contact Fatek Automation Corporation or your local authorized distributor. They may require proof of ownership before assisting with a reset.
Offline Backups: If you cannot bypass the password, the standard practice is to use your original offline project file. You can overwrite the existing program on the PLC with your backup, which will also reset or clear the password protection.
Hardware Bypass (Communication Modules): Some communication boards (like the FBs-CBEH) have physical jumpers that can temporarily disable password protection for configuration purposes. This typically requires opening the module's plastic cover. 2. Fixing Vulnerabilities ("Cracking" Risks)
Third-party "password cracker" tools often exploit known firmware flaws (such as CVE-2022-2003) where a PLC might send its password in cleartext if triggered by a specific request. The Battery Drain Method (Legacy):
Firmware Updates: To "fix" the risk of being cracked, ensure your PLC is running the latest OS. Updates are performed using the FBs OS Update utility (os_update.exe) and the latest image files from the Fatek Download Center.
Advanced Security Settings: In WinProladder, you can enable higher security levels (Level 1–15) or "User Mode," which requires both a username and password. 3. Warning: Risks of Third-Party Crackers
Searching for "crack fixes" often leads to malicious software. Security researchers (e.g., Dragos) have found that many PLC password-cracking tools are actually malware droppers. Support | FATEK AUTOMATION CORP.

Providers: Platforms like PLC Unlock BD offer decryption services and software for various PLC models. 3. Factory Reset (Last Resort)
If you cannot recover the password and do not need the existing program, you can perform a factory reset.
Loss of Data: This will permanently delete the user program and data inside the CPU.
New Program: After the reset, you can download a new project to the PLC and set a new password of your choice. 4. Advanced "Project File" Bypass
If the password is set on the project file (.fpro) rather than the PLC hardware itself, certain modified versions of WinProladder may be able to bypass the prompt. This is highly dependent on whether the protection was applied to the source file or the physical unit. Fatek plc password cracker | PLCtalk - Interactive Q & A
FATEK PLCs are highly reliable controllers, but forgotten passwords can disrupt operations. Attempting to bypass these security locks carries both technical challenges and severe cybersecurity risks.
The following report covers the security architecture of FATEK PLCs, the risks associated with third-party "cracking" software, and official procedures to recover or reset locked equipment. 🔐 Understanding FATEK PLC Security
FATEK programmable logic controllers (such as the FBs, B1, and B1Z series) utilize distinct password layers to protect intellectual property and machine operations:
Project File Password (.prj): Encrypted within the WinProladder project file. Without this, the ladder logic cannot be opened or edited on a PC.
PLC CPU Password: Stored directly in the PLC hardware's non-volatile memory. This is required to go online, upload the active program from the CPU, or download a modified program to it. ⚠️ The Danger of Third-Party "Crack" Tools
A search for "FATEK PLC password crack" often yields links to third-party executable files, shady recovery software, or "direct unlock" scripts on social media and file-sharing sites.
🚨 Warning: Malware RiskIndustrial cybersecurity researchers have documented that software advertised online as "PLC password crackers" or "HMI unlockers" frequently harbor highly destructive malware. Threat actors exploit the desperation of engineers locked out of critical systems to bypass corporate firewalls and install backdoors or ransomware directly into industrial control environments. 🛠️ Official Fixes and Recovery Procedures
If you are locked out of a FATEK PLC and require access for maintenance or modifications, you must utilize verified, legal channels. 1. Contact the Original Machine Builder (OEM)
The fastest and safest way to recover a password is to reach out to the system integrator or the original machine manufacturer. They typically maintain backups of the original, unprotected WinProladder project files or keep an internal record of the master CPU passwords utilized during deployment. 2. Contact FATEK Technical Support
If the original builder is no longer accessible, you can contact FATEK Automation Corp or an authorized regional distributor.
You will likely be required to provide physical proof of ownership of the machine to maintain compliance and security.
While tech support generally cannot extract a forgotten password remotely, they can guide you through advanced hardware recovery options specific to your firmware. 3. Last Resort: Full Memory Clear (Factory Reset)
If access to the logic is not strictly required but the hardware needs to be reused or reprogrammed, you can perform a full memory clear. This process strips all security passwords but permanently erases the existing logic program.
The Procedure: Many legacy FATEK models (like the FBs series) have internal hardware pins labeled CLR.
The Process: By placing a jumper on the CLR pins, powering the unit on for a few seconds, and then removing it, the internal non-volatile memory is wiped clean.
The Result: The PLC returns to an unprotected factory default state, allowing you to establish a brand-new connection via WinProladder and download a new program without a password prompt.
