  1. we have a machine with cpu1215c 6ES7215-1HG40-0XB0 firmware v4.3 and the cpu has been programmed with tia portal v14 sp1. we do not have the source of project and we just want to upload it. now when we want to upload the project from cpu to tia portal 14 it says that the firmware of online cpu is 4.3 and the offline is 4.2 and you cannot upload!! how is it possible? how we can upload project when v14 does not have firmware 4.3?!! if we use tia portal 16 it says that the the online cpu has been programmed with tia 14 and you cannot upload it to tia 16!!   what has siemens thought for this endless loop?
