4.9 Firmware update/restoring the firmware
4.9.1 Updating the firmware via FoE (File Access over EtherCAT)
The bus node supports FoE. It is possible to load the firmware onto the module via the EtherCAT master
(provided that it supports this function).
The current firmware version can be found on the Festo website
( www.festo.com/sp).
Note
Loss of function of the device
If the supply voltage fails while the firmware is being written, it will result in a loss of
function of the bus node.
• Do not interrupt the firmware download and writing process under any circum-
stances.
When using the TwinCAT 3.x configuration software proceed as follows:
1. Copy the new firmware into a directory.
2. Switch the bus node to the status BOOTSTRAP.
The “RUN” LED on the bus node flickers; the “Current State” in the TwinCAT 3.x configuration
program changes to “BOOT”.
