Hi,

I am using CPU 412-5H. I am trying to download CFC program to CPU. Please find attachment for the error.

After getting error, I had put CPU is in STOP mode. after that i also got the error "The download of F-blocks is not allowed with online CPU connection."

I had also followed procedure given on "https://support.industry.siemens.com/tf/WW/en/posts/download-of-f-blocks/18330?page=0&pageSize=10".

In Edit safety program, I didn't get "Download" button which is to be activated as mentioned above .

Please give solution this problem.

Have nice day
