Wie kann ich die Uhrzeit meines PC mit der EMC synchronisieren

  • Die EMC Professional NET kann direkt über Ethernet als Sntp Server abgefragt werden.
  • Zum Beispiel geben Sie bei Windows 10 einfach die IP Adresse der EMC in den Datum/Uhrzeit Einstellungen an.
  • Darüber hinaus sind zahlreiche Ntp Clients für diverse Betriebssysteme verfügbar.

Ntp Test mit w32tm /stripchart

Mit Hilfe des Programmes w32tm können sie überprüfen ob Ihr NTP Server erreichbar ist und auf NTP Anfragen antwortet. Statt wie hier im Beispiel 'ntp1.ptb.de' geben Sie z.B. die IP Adresse Ihrer 'EMC Professional NET' an. 

C:\>w32tm /stripchart /computer:ntp1.ptb.de /dataonly /samples:3
Tracking ntp1.ptb.de [192.53.103.108:123].
Collecting 3 samples.
The current time is 21.09.2017 14:28:34.
