Lines or star topologies can be implemented using the SMGM-SI segment interface.
TIPS AND RECOMMENDATIONS!
Information about the SMGM system
Cable lengths
Please ensure adherence to the maximal permissible cable lengths for the respective
devices - see section “5 SMGM technical data”.
Switch latency period
Superfluous “daisy-chaining”
1
lead to higher latency! The SMGM-SI modules must al-
ways be connected on the highest switch level.
Diagnosis segment
To use the HF diagnostics of the mobile participants, the SMGM-SC must be connected
to a defined rail segment on which only one SMGM-DI or BCC/SMGM has mechanically
enough space together with both couplers.
