Time settings
It is recommended to set a transparent time with
Power profile. The Ethernet switch then only
corrects and forwards the PTP messages and
cannot become the PTP master.
This concludes the Time Settings activities.
Switching Settings (VLAN)
The traffic segregation is especially essential for
the process bus to reduce data traffic and to let it
go only where needed (for example GOOSE, SMV
shared between protection relays should not be
sent to the control system, SMV should only be
sent where required).

Traffic filtering in managed Ethernet switches
can be done via logical separation of the data
traffic to several VLANs or via multicast MAC
address filtering for ports.
Select “VLAN Settings” from the menu to open
the VLAN settings dialog box. (Figure 17) Follow
the diagrams as shown in Figures 18 and 19.
The PTP profile must be enabled on all ports. The
Peer to peer delay interval is definite for power
profile 1s.
Set the time values under the PTP settings as
shown in Figure 16.
