Firmware or project update


To use the latest features of the EA HMI-Series, it might be necessary to update the internal firmware of the module. On the other hand it might be necessary to update the HMIDesigner project in the field.


Firmware and project-update via serial interface and Windows PC:

It doesn't matter if the module is connected via modbus or short / small protocol. The tool uniTransfer is able to use both:


  • Save the firmware file (e.g. EA_uniTFTs_V1_1.fw) to your local drive. The HMIDesigner project file (e.g. MyFirstProject.eup) can be found in the root directory of your project path.
  • Connect the EA HMI-Series module with your PC
  • Start uniTRANSFER.exe (found in the Simulator_and_Tools folder of the HMIDesigner installation) and select the correct interface to the EA HMI-Series.
  • Drag'n'Drop the firmware or the project file to the EA uniTRANSFER window.



               

  • After transferring the data, a manually reset needs to be performed, then the firmware will be loaded automatically after restart. Attention: Please do not switch of the module while updating.



Firmware or project update via serial/network interface (Small/Short Protocol)

The firmware file also can be transferred to EA HMI-Series  with any system. To do this, transfer the contents of the * .fw / *.eup file 1:1 (with protocol in packets) to the module. The transfer progress will become visible on the display module. After successful transfer, a data check will be done automatically. If the data is correct, the update starts automatically. Attention: Please do not switch off the module while updating.


Firmware or project update via serial/network interface (Modbus)

To update the firmware or project via Modbus with any system, the usage of user-defined function codes is mandatory. To do this, transfer the contents of the *.fw / *.eup file 1:1 to the module. The content must be divided into multiple Modbus packets and send as user-defined function. The transfer progress will become visible on the display module. After successful transfer, a data check will be done automatically. If the data is correct, the update starts automatically. Attention: Please do not switch off the module while updating.
