Version: 2.8
In this example in Fig.
Change dialog
, an EL3201-0000-
0017
was found, while an EL3201-0000-
0016
was
configured. In this case the configuration can be adapted with the
Copy Before
button. The
Extended
Information
checkbox must be set in order to display the revision.
Changing the ESI slave identifier
The ESI/EEPROM identifier can be updated as follows under TwinCAT:
• Trouble-free EtherCAT communication must be established with the slave.
• The state of the slave is irrelevant.
• Right-clicking on the slave in the online display opens the
EEPROM Update
dialog, Fig.

Update
Fig. 189: 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.
