Used to enter the HMI's underlying OS (usually WinCE) to calibrate the touch screen or change IP settings. 3. How to Set or Change Passwords
This highlights a common vulnerability in industrial systems: the reliance on default passwords or weak recovery methods. Many facilities operate HMIs with default factory passwords (often simple sequences like "888888" or left blank) because operators prioritize ease of access over security. Furthermore, while tools exist to crack or remove MCGS project passwords, their existence underscores the need for integrators to avoid relying solely on the software password for critical security. If a malicious actor gains physical access to the HMI USB port, a weak system password offers little resistance.
This method works for most MCGS TPC series HMIs (TPC7062, TPC7062Ti, TPC1261, etc.).
This will wipe the existing program off the HMI. Ensure you have a backup of the project file before proceeding.
