Hello Amit Welde Unfortunately life with CFC ( PCS7 ) is not so easy as it is with a standard S7-400H. In a S7-400H system ( Without CFC ) you can make most downloads without both CPUs going to STOP Mode ( By following proper download sequence ) However Downloading CFC to a H system is quite another ballgame.Most Major changes ( Changes in Block interface, Interconnection etc ) would call for a full download and both CPUs will go to STOP. This at times defeats the very porpose of a H system. However if you are careful, you can reduce this condition ( If not avoid completely ) The Following FAQs include some information and Tips for avoiding such situations.

Changes Only was enabled during download or you have only option of entire download ??? In the manual read Chapter 3.12 to know more about Changes Only and Entire Program.

HelloAmit Welde,
Wouldn't make much difference because the download restriction comes from the nature of CFC not from being PCS7. As described earlier that some changes may require a STOP of both CPUs. So, we can't speculate the reason as long as we don't know what changes you have made and download procedures you have followed.
Best regards, H-H
