Symptoms
The HMI displays a configuration mismatch error after a project download. The screen shows 'Project version does not match HMI firmware version'.
Possible Causes
- Project compiled with a newer version of the configuration software
- HMI firmware not updated to match the project requirements
- Project downloaded to the wrong HMI model or variant
- Configuration file corrupted during USB download
Troubleshooting Steps
- Step 1: Check the project software version and compare it to the HMI firmware version
Update either the software or firmware to match - Step 2: Verify the target HMI model number matches the project's configured device
Recompile the project with the correct target if the model is wrong - Step 3: Re-download the project after cleaning the download folder on the USB drive
Use a freshly formatted USB drive to eliminate file corruption - Step 4: If the error persists, perform a factory reset on the HMI and re-download
Factory reset clears all settings; back up data first
How to Reset
Reset: The configuration mismatch alarm clears after a successful project download with matching versions.
Common Replacement Parts
- USB drive: 8GB, FAT32 format (Use a new, formatted drive for project downloads)
- Firmware update file: OEM-specific format (.pkg or .bin) (Download from manufacturer support site)
