For administrative or factory-level access to the HMI hardware itself (such as changing network settings or performing system updates), specific default or factory passwords are often required. Factory/Login Password
(Kunlun Tongtai) devices, passwords are used for both project protection and system-level access. In many industrial applications, "factory password"
By binding input boxes to local HMI string variables (e.g., Current_Password , New_Password ), you can create a "Change Password" screen. A simple data-change script validates the input:
Assumptions: A numerical input box writes to Data_Entry (PLC Register LW0). The correct password is stored in Correct_PW (PLC Register LW10).
: Technicians sometimes use a USB drive with specific files (like ChgStart ) to bypass or update the environment, which can trigger a login interface once the "burning" process is successful.
Note: String comparison is case-sensitive in MCGS. Convert both to upper case using StrUpper() if needed.
: A known factory password used during certain programming and restart procedures. 2. The Lock: Application-Level Security
This article explores how , including how to unlock or bypass security, manage user access, and reset passwords in the MCGS Embedded Configuration Software. 1. Understanding MCGS HMI Security Structure
(Try pressing enter without entering a password). Method 2: Accessing the System Menu via Cold Boot
: Technicians sometimes pull the runtime file from the hardware storage card and inspect specific hex addresses associated with user tables to identify password hashes or plain-text values.
Prepare a USB drive with the necessary recovery files (often named CHgstart or similar). Insert the USB into the HMI and restart.
Before clicking a single button in MCGS software, you must understand the control logic. MCGS does not have a built-in "User Manager" like Siemens WinCC or Weintek EasyBuilder Pro. Instead, it relies on:
