Download Operation Aborted - Siemens SIMATIC S7 F Manual

Programming
Procedure
1. Change the Safety Program and compile it (see "Compiling a Safety
Program"
2. If simulation mode is activated, deactivate it (see "Testing a Safety Program
Offline with S7-PLCSim").
3. Deactivate safety mode (see Deactivating Safety Mode).
4. Choose the PLC > Download > Changes Only menu command in CFC.
Always respond with "Yes" when you are asked to confirm that you want to
register the CPU for a test.
5. If necessary, repeat steps 1 to 4 to download changes step by step, for
example.
6. Activate safety mode (see "Activating Safety Mode").
7. Choose the Options > Edit Safety Program menu command in SIMATIC
Manager.
In the "Safety Program – S7 Program" dialog box, activate the "Online" and
"Offline" options one after another and check whether the overall signatures (online
and offline) match (see "Checking the Overall Signatures" in the section entitled
"Initial Acceptance of a Safety Program"). If they match, downloading has been
successfully completed. If not, repeat step 4 of the download operation. In the case
of S7 FH systems you must carry out this comparison for the two CPUs.
Safety Note – Download Operation Aborted
!
If the download operation is terminated, you must repeat downloading the changes
(step 4) and check the overall signatures online and offline (step 7) to ensure the
consistency of the data in the load memory and the working memory.
