For updating the FPGA firmware
• of an EtherCAT coupler the coupler must have FPGA firmware version 11 or higher;
• of an E-Bus Terminal the terminal must have FPGA firmware version 10 or higher.

Updating an EtherCAT device
The following sequence order have to be met if no other specifications are given (e.g. by the Beckhoff
support):
• Switch TwinCAT system to ConfigMode/FreeRun with cycle time >= 1ms (default in ConfigMode is
4ms). A FW-Update during real time operation is not recommended.
