AES Key Refresh Event

[ME_Rotronic]

Hi,
AES Key Refresh stands for the encryption refresh between two RMS participants.
It is triggered
- with the start-up
- after a communication interruption within the network
- after a power off/on
- after max. 48h

Hallo everyone

Within my RMS System I see an AES Key Refresh at Events.
What does it mean and when is it triggered?
