The certificate is printed as text on the device. It can also be scanned from the printed QR code via
a webcam.
The list of all device certificates can be managed in the ETS panel Reports – Project Security.
This initial key is required to safely put a device into operation from the start. Even if the ETS
download is recorded by a third party, the third party has no access to the secured devices
afterwards. During the first secure download, the initial key is replaced by the ETS with a new key
that is generated individually for each device. This prevents persons or devices who may know the
initial key from accessing the device. The initial key is reactivated after a reset to factory default
settings.
The serial number in the certificate enables the ETS to assign the correct key to a device during a
download.
