You can download the boot application to the controller only when the defined dongle (license key) is connected to the computer.

The dongle is provided by ABB AG or by the respective hardware manufacturer. The firmcode is displayed. Type in the delivered product code.

“Encryption with license management”

You can download the boot application to the controller only after you have specified the product code and firmcode, and the respective dongle is connected to both the development computer and the controller. You receive the codes from the vendor that manages the licenses.

“Encryption with certificates”

You can download the boot application to the controller only when a valid certificate exists for it. The “Certificates” group is enabled. See the description below.

The option is already selected if the “Enforce encryption of downloads, online changes and boot applications” option is selected on the “User” tab of the “Security Screen” view.

You can also select the “Digitally sign application code” option.
