Figure 678: Example of usage of binary signal transfer for position indication

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

Ethernet Port X6

Ethernet Port X3

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).
