I have a project comprised of a S7 1200 and a KTP400 Basic Panel. My problem is as follows:

I need to download the project program (built in TIA v13.0), which contains the code for both the CPU and the Panel, onto a SD card and insert the card into the CPU base. I no longer have access to the skid as it has been shipped to the client already, so I thought I could upload the updated programs to  SIEMENS SD card, ship the card to the client. Once the client has the card is it possible for him to insert the SD card into the PLC and the program to update?

Is it possible to transfer both applications (for CPU and HMI) from this card, alone,to the respective devices? I mean without actually having to go on-site and connect to the PLC via PC.

I would appreciate any feedback from you folks.

Thank you in advance!
