Software update k.air +030220981 rel. 1.2 - 01.12.2020
13.3 Update with fi le transfer via F T P
k.Air controllers include an FTP server that allows access to the public partition of the fi le system. It is thus possible to read,
modify, create and remove fi les and folders. A client program is used to transfer fi les with the FTP protocol, such as “FileZilla”.
The default username for accessing the fi le system is “anonymous”, with no password (to protect the contents of the public
fi le system from unauthorised access, diff erent users can be created, giving each user diff erent access profi les). For further
details, see the c.pCO 0300057EN.
To update the application program via FTP:
1. Open a fi le uploader with FTP protocol (e.g. FileZilla).
2. Enter the IP address of the c.pCO controller and the access credentials (default user “anonymous”, no password).
3. Drag and drop the .ap1 update fi le from the computer folder to the “UPGRADE” folder on the c.pCOn controller.

Note: set the following confi guration in FileZilla:
• Edit > Settings > Connection -> set timeout in seconds = 0
• Edit > Settings > Transfers > set maximum simultaneous transfers to 1
4. Enter the system menu (press Alarm and Enter for 3 s) and select “UPGRADE”. Proceed as described in the previous paragraph.
Note: after uploading the update fi le to the upgrade folder via FTP, the update can also be started remotely via a virtual ter-
minal. For further details, see the c.pCO 0300057EN.
