Fig. 202: EEPROM Update
The new ESI description is selected in the following dialog, see Fig. Selecting the new ESI. The checkbox
Show Hidden Devices also displays older, normally hidden versions of a slave.

A progress bar in the System Manager shows the progress. Data are first written, then verified.
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 Ether-
CAT slave therefore has to be switched off briefly in order for the change to take effect.
