Hi,
unfortunately I’m not a safety expert, so I hope that others in the community can give more precice information on that topic.
But what I know is, that the safekey does not only contains the licences, but also the program an parameter flash memory for the device.
So, if there’s no safekey I’m pretty sure that there’s no possibility to download software to the device because it can’t be stored anywhere on the safelogic.
If the communication is activly refused because of a missing safekey, I don’t know. But I can imagine, that because of the missing safekey’s memory the safelogic cannot even boot up into a state where communication is possible?
Maybe other community members know more about that.
Best regards!
