Im EtherCAT-Kommando sind 4 Bytes für die Adresse reserviert, die je nach

Kommandotyp, eine andere Bedeutung haben können: Bei Autoinkrementbefehlen
|

sind die ersten zwei Bytes die (negative) Autoinkrement-Adresse, bei Knoten-

adressierten Befehlen entsprechen sie der Knotenadresse. Das dritte und

vierte Byte entspricht in diesen Fällen der physikalischen Speicheradresse

der logischen Adresse.
