The MCGS software ecosystem utilizes distinct security tiers to control access to different layers of the HMI project. These levels prevent unauthorized tampering, copying, or reverse-engineering of the machine control logic.

If verified, _UserLevel updates to match the user's assigned privileges.

Even experienced engineers get stuck. Based on real support forums, these are the top reasons fails:

: North American users frequently report that the software won't install or run correctly on standard English Windows versions, even with language packs.

Use the MCGS software tools menu to create an HMI initialization or firmware update disk. Insert the drive into the HMI power-cycle the unit.

: When designing an HMI project, each object (like a button or numeric input) has a "Security" or "User Level" property. If a user's logged-in level is lower than the object's requirement, the button will either be hidden or non-functional. Password Management

Re-download the project to the HMI to apply the new security settings. 2. Resetting a Forgotten Password

Set within the project communication parameters. When an engineer connects a laptop via USB, Ethernet, or serial cable to upload data from the HMI or download a new runtime project to it, the software prompts for this password.

If you encounter an "anomalous" password screen that appears even when trying to access basic settings, it is likely that the previous owner implemented a custom "application password" that does not match the default factory settings.

To troubleshoot password-related issues in MCGS HMI, follow these steps:
