This paper explores the security mechanisms and operational procedures for password management within MCGS (Monitor and Control Generated System) HMI software. 1. Introduction to MCGS Security
Create a dedicated login screen containing input boxes bound to the system variables _SysUser and _SysPassword . Utilize built-in functions to validate the inputs against the User Manager database upon pressing the login button. Advanced Password Operations with Scripts
It’s important to note that MCGS security typically operates on two distinct levels:

Open your project in MCGS embedded or professional software. Click on the project explorer tree, locate the system parameters, and open the user configuration window to establish your default administration credentials. Step 2: Configure Object Properties
These grant access to the underlying Windows CE network settings, calibration, and clock synchronization menus. 3. How to Clear or Recover a Forgotten Project Password
Typically, developers define levels (e.g., Level 0: Operator, Level 1: Maintenance, Level 2: Engineer). Higher-level tasks require higher-level passwords. This paper explores the security mechanisms and operational
Visibility and operability attributes of screen components instantly refresh based on the new _UserLevel . Recovering Lost MCGS Passwords
If the original programmer set up user levels (e.g., Operator, Technician, Administrator), there is no "universal" default. However, many developers leave the Admin password as "1" or "888888" during testing.
Navigate to HardDisk -> StartUp and look for files named CHgstart . Utilize built-in functions to validate the inputs against
IF Pwd_Input = Sys_Pwd THEN !SetDevice(DeviceName, Cmd, Value) ' unlock function Pwd_Input = 0 ELSE MessageBox("Wrong password") ENDIF
Use database-driven security where possible. This allows you to manage multiple users with different access levels (e.g., Level 0 for operators, Level 1 for supervisors) so that one forgotten password doesn't lock everyone out.
: Always change factory default passwords immediately during the initial commissioning phase.
