Drawbacks • If the connection to the NTP server is interrupted (e.g. Internet connec- tion fails, modified firewall rules), the Access system time between the Access server and Access end devices may differ. • If there is a longer interruption, this may result in a time deviation. • Registration and operation of the Siedle App (ALSA 270-0) on the Access system is only possible if there is no time deviation. • If the time deviation is more than 59 seconds, no more switching commands are executed for safety reasons.
