hi everyone,

i have HMI model kTP400 basic, my question is, can i upload the program from hmi through tia portal?because ialready tried, but is failed. i can download only from tia portal.

Unfortunately, you cannot upload the program from the panel to TIA Portal. Siemens has a utility program called ProSave that can be used to make a backup of what is in the HMI, but it is not editable once saved.

For the KT series of touchscreen HMI's, you will need make sure you have a good copy of the project software (I like to archive my projects at least once a day if I have made changes). TIA Portal can only be used configure, make changes, and download to the panels.
