If you download a project via Operator Terminal Expert 3.2 to HMI the Firmware will be updated. EOTE will upgrade downgrade always the Firmware of the HMI.

hello

i have backup of old hmi in .vml format , can i open it in software?

So far I now a reloading of the VML file will not work in EOTE. The VML file contains the firmware and the compiled project file. To open it in the software you need the EOTE project file.

can i use EOTE v 4.1 as 3.2 is not available. 

if HMI version will be upgraded to 4.1 , then will i be able to copy backup of v3.2 HMI's backup?
