Further information is available to download from the Weidmüller Support Center.
When downgrading the firmware, please also observe the document u-OS Firmware Migration Guide in the Weidmüller Support Center.
For firmware downgrades, we recommend connecting your computer with the controller via USB. Depending on the used downgrade file IP address changes and protocol changes will occur.
A firmware downgrade between minor versions is not recommended (e.g. from 2.1 to 2.0). If you still need to downgrade the firmware, make sure to perform a factory reset first.
