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.
Fig.203: Selecting the new ESI
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.

Beckhoff EtherCAT slaves feature serial numbers applied by laser. The serial number has the following
structure: KK YY FF HH
KK - week of production (CW, calendar week)
YY - year of production
FF - firmware version
HH - hardware version
