7.1 Changes to the AS configuration
Important rules for working with CiR
● Use Ctrl+Alt+F (menu command "Station > Check CiR Capability") to check if the
currently open configuration can be loaded via "Download station configuration in RUN
mode" prior to making a change in HW Config. This consistency check is also performed
automatically before the download is carried out.
● If a distributed station has an orange background color, this color indicates that the
station has been added or can be removed via CiR.
● New slaves are dragged and dropped to the CiR object of the DP master system and not
directly to the master system.
● New modules for ET 200M/ET 200isP are dragged and dropped to the CiR module of the
station.
● Use the "Save and Compile" function only after successfully downloading the
configuration changes. If you cannot perform the download for some reason, you can
reverse your configuration changes by closing HW Config.
● Download each configured change to the AS individually using "Download station
configuration in RUN mode". You can use such "small" changes to shorten the CiR
synchronization time to a few milliseconds. The new I/O is registered in the AS during the
CiR synchronization time. The entire processing cycle is interrupted.
● After each HW Config delta download, the charts need to be updated (including the
"Generate module drivers" option). The PCS 7 driver blocks are then automatically
adapted to the modified I/O.
Note
The CiR function only supports addition or deletion for F I/Os. You can find further
information in the section titled "Configuration in Run (CiR)" in the "SIMATIC Industrial
Software S7 F/FH Systems – Configuring and Programming"
(https://support.industry.siemens.com/cs/ww/en/view/109742100) manual.
