Hi nguyenkuong.
You cannot directly take the runtime file from the TP270 and download it to the MP270.
It has to be converted to the MP270, and for this you need the original Protool or WinCC Flex project file.
There is a slim chance that there is a backup of the project file on the panel. In that case there must be a CompactFlash card in the slot in the rear of the panel. If there is, you can try to use the Upload function in Protool or WinCC Flexible (not Prosave).
That said, most programmers dont use the ability to store a backup of the project on the panel.
