Delta HMIs use several layers of security to protect intellectual property:

: Many tools advertised as password crackers for PLCs and HMIs are actually delivery mechanisms for malware or exploit zero-day vulnerabilities in your engineering workstation.

: These specialized tools, like those from PLC247 , are designed to read "Project Passwords" directly from the source files.

: Controls user access to specific screens or buttons on the HMI during operation. Delta HMI Password Unlock Tools

: Various providers offer HMI unlock services for DOP-A, DOP-B, and DOP-100 series. This often involves sending the hardware or an EEPROM chip dump to the service provider.

: Restricts the ability to transfer data between a PC and the HMI hardware.

: Prevents unauthorized opening of the .dps , .dpa , or .dpb project files in DOPSoft .

: Before using third-party software, check if the system is still using factory defaults. For many Delta HMI projects, the default highest security password is 12345678 . Risks of Using "Crack" Software
