Aborting the "Complete Download" function
If a complete download is aborted, it will no longer be possible to perform an online delta
download. The online delta download is available again only when a complete download has
been successfully performed.
Aborting the "Delta Download" function
A delta download can be repeated after aborting a prior delta download, in contrast, whereby
only the missing components will be copied.
You can find a general description on monitoring and changing block interfaces and
parameters in the section titled "Testing user programs" in the "SIMATIC Process Control
System PCS 7 CFC for SIMATIC S7"
(https://support.industry.siemens.com/cs/ww/en/view/109748700) manual.
Parameter changes can be made via test mode in the CFC editor or in the process object
view.
However, you can only change the values of non-interconnected inputs of an FB instance;
outputs and interconnected inputs can only be monitored. In general, inputs/outputs of FC
instances cannot be changed, because FCs do not have instance DBs.
The parameters of all CFC charts contained in the chart folder of the active chart whose AS
data was changed, for example via OS operations, can be saved in the configuration and
read back. This also applies to limits and controller settings, for example.
A general description of how parameters are read back is included in the manual titled
"SIMATIC Process Control System PCS 7 CFC for SIMATIC S7"
(https://support.industry.siemens.com/cs/ww/en/view/109748700).
Note
As of PCS 7 V8.0, there is the option of reading back charts cyclically and automatically.
