4.1.4 Private VLAN
Layer 2 > Private VLAN
Figure 4-5
All the Private VLAN types are configured in the "Layer 2 > Private VLAN" menu.
For an explanation of the Private VLAN types, see Section 4.1.1. The following
settings are provided for the Service Bridge:
(1) Private VLAN Type:
– For the VLAN ID 1 (Port 1 – Plant bus): Primary PVLAN
– For the remaining VLAN IDs (Port 2..n – PNSeg): Isolated Secondary
PVLAN
(2) Primary VLAN ID: 1, because all Secondary PVLANs are assigned to the
Primary PVLAN (Plant bus).
With this configuration, communication is possible between VLAN ID 1 (Port 1) and
all PROFINET networks (VLAN ID 2 .n - Port 2..n). At the same time, the
PROFINET networks are located in various Isolated Secondary PVLANs and thus
remain logically separated from each other.
