5.5 Installation und Konfiguration von Master <–> Master (SMMC) und
Master <-> Slave (SDDC)
The SMMC communication enables the safe data exchange of 2 byte between several SDDC
masters.
The communication takes place without master for the coordination of the data. Thus data
exchange between available participants is always given.
Through this principle, an incomplete or separate network can operate in its partial regions.
In order to be able to coordinate several SDDC masters with different cycle times, a SMMC
cycle time is parameterized, which must be adhered to by all participants.
This cycle time is the smallest common multiple of the cycle time of the individual participants.
