Sync Manager communication
Der Sync Manager steuert die Mailbox und Prozessdaten-Kommunikation des CMMT zu den anderen
Netzwerkteilnehmern (z.B. Steuerung).The Sync Manager controls the CMMT mailbox and process
data communication to the other network devices (e.g. controller).
The following table describes the fixed assignment of communication type and transmission type to
the Sync Manager.
