Figure 13-16. Current Differential Relay Comms Settings
Comms Settings Definitions:
Transmit Addr 1 or 2 (0-4095 inc 1)
This sets the transmit address for communications channel 1 and/or 2. It may be from 0 to 4095 in
increments of 1. The transmit address setting at the local relay must match the receive address setting
at the remote relay for communications to take place.
This prevents inadvertent communications network cross-connects from creating incorrect relay links.
Receive Addr 1 or 2 (0-4095 inc 1)
This sets the receive address for communications channel 1 and/or 2. It may be from 0 to 4095 in
increments of 1. The transmit address setting at the local relay must match the receive address setting
at the remote relay for communications to take place.
This prevents inadvertent communications network cross-connects from creating incorrect relay links.
RS# 1 or 2 Loss of Time Sync causes alarm
Enable to give a minor alarm if the remote station and local real-time clocks are not synchronized. The
default is disabled. Note that the current differential algorithm does not rely on real-time clocks so loss
of time sync between them is of no consequence for the protection function.
