Figure 678: Example of usage of binary signal transfer for position indication
change
Additional dedicated channel can be used to transfer binary signal infor-mation
quickly without the need to configure GOOSE. This minimizes the configuration
effort since configuration templates can be directly used when signal transfer is
required only for point to point instead of multipoint.
In addition to X6 Ethernet port which is tied to PCSITPC1 and BSTGAPC1-2, X3
Ethernet port can be configured to dedicated channel mode. It also requires
PCSITPC2 block for supervision and one of the BSTGAPC3-4 for signal connections.
Analog signals are not available for this channel.
Dedicated channel Functions Description
Ethernet Port X6 BSTGAPC1-2,
PCSITPC1,
LNPLDF1
Includes analog data and can be used for line differen-
tial application as well as for binary signal transfer.
Ethernet Port X3 BSTGAPC3-4,
PCSITPC2
Analog data cannot be either send or received. Only
used for binary signal transfer. Ethernet port must be
set to dedicated channel mode.
Relay pairs exchanging only binary signals can be connected to either port. However,
one must verify that connector types match especially when X3 is connected to X6
(SFP module).
