Es gibt folgende Domains:

loaded once at startup, mostly by a
PLC.

quite often in normal operation.

Tabelle 38: Daten-Domains
Oft gibt es ein Topic für alle Gateway-bezogenen Informationen und Topics
für jeden Port. Alle Identity-Topics werden nur einmal beim Gerätestart
veröffentlicht, da diese Information statisch sein sollte. Alle anderen Topics
werden, abhängig von ihrer Konfiguration, entweder in einem festen Intervall
veröffentlicht oder manuell ausgelöst.
