A progress bar in the System Manager shows the progress. Data are first written, then verified.
Note
The change only takes effect after a restart.
Most EtherCAT devices read a modified ESI description immediately or after startup from
the INIT. Some communication settings such as distributed clocks are only read during
power-on. The EtherCAT slave therefore has to be switched off briefly in order for the
change to take effect.
