Simplified update by bundle firmware
The update using so-called bundle firmware is more convenient: in this case the controller firmware and the
ESI description are combined in a *.efw file; during the update both the firmware and the ESI are changed in
the terminal. For this to happen it is necessary
• for the firmware to be in a packed format: recognizable by the file name, which also contains the
revision number, e.g. ELxxxx-xxxx_REV0016_SW01.efw
• for password=1 to be entered in the download dialog. If password=0 (default setting) only the firmware
update is carried out, without an ESI update.
• for the device to support this function. The function usually cannot be retrofitted; it is a component of
many new developments from year of manufacture 2016.
Following the update, its success should be verified
• ESI/Revision: e.g. by means of an online scan in TwinCAT ConfigMode/FreeRun – this is a convenient
way to determine the revision
• Firmware: e.g. by looking in the online CoE of the device
Risk of damage to the device!
Note the following when downloading new device files
• Firmware downloads to an EtherCAT device must not be interrupted
• Flawless EtherCAT communication must be ensured. CRC errors or LostFrames must be avoided.
• The power supply must adequately dimensioned. The signal level must meet the specification.
In the event of malfunctions during the update process the EtherCAT device may become unusable and re-
quire re-commissioning by the manufacturer.

Attention regarding update of the ESI description/EEPROM
Some slaves have stored calibration and configuration data from the production in the EEPROM. These are
irretrievably overwritten during an update.
The ESI device description is stored locally on the slave and loaded on start-up. Each device description has
a unique identifier consisting of slave name (9 characters/digits) and a revision number (4 digits). Each slave
configured in the System Manager shows its identifier in the EtherCAT tab:
