Hello dear all, 

I have installed the STEP7 professional V12 (TIA Portal) on my PC with windows xp sp3. 

Now i want to upload a project data from cpu s7-1200; but the upload to device option is disabled (unselectable) for me.

May you please tell me that what is the wrong?

Best regards

Tekabi 

Hello Tekabi.

Check this FAQ. Online Tech just pointed it out in an earlier topic.

Hope this information helps you.

Hi Dear Rescobedo,

Thanks for your best reply.

I will test the uploading again, with these new information.

Best regards
