Restoring the firmware with the Festo Field Device Tool (FFT)
The Festo Field Device Tool enables you to restore the operational capability of the bus node (e.g. after
a failed firmware update via FoE).
The FFT software can be found on the Festo website (
www.festo.com/sp).
Install the FFT software on a PC or notebook.
1. Disconnect the power supply of the CPX terminal and, if relevant, the compressed air supply.
2. Remove the bus node from the EtherCAT network.
3. Connect your PC directly to the bus node via the network connection.
4. Set both switching elements on DIL switch 2 of the bus node to ON (
Section 3.2).
5. Start the “Recovery” function in the FFT under the “Actions” tab and select the corresponding com-
mand in the “General” group of instructions.
