Fig. 8-4 Recommendation for structuring an SMGM system (mobile participants not shown)
When structuring the SMGM system, as shown in the figure, the data traffic is highest on Switch 1. Here, all
the frames coming from the system are transfered to the PLC. To ensure the stability of the PROFINET network,
the maximum utilization should amount to 20% (on Switch 1). This maintains the cycle time required by the
PROFINET specifications.
