Trame de commande

French to German Tech/Engineering Telecom(munications) Trame de commande à distance

I would appreciate if a fellow translator could , please, help me out with a technical French expression in the area of telecommunications. The expression is "trame de commande". Context: "Trame de commande à distance d'actionneurs utilisés dans un système domotique, un bit de relais débutant la seconde partie".
Thank you.
