5.7 INPUTS / OUTPUTS
In the above architecture, Devices 1 and 3 do not communicate directly. Therefore, Device 2 must act as a 'bridge'. The fol-
lowing settings should be applied:
UR IED 1:
DIRECT OUT 2 OPERAND:
DIRECT INPUT 5 DEVICE ID:
DIRECT INPUT 5 BIT NUMBER:
DIRECT INPUT 6 DEVICE ID:
DIRECT INPUT 6 BIT NUMBER:
UR IED 3:
DIRECT OUT 2 OPERAND:
DIRECT INPUT 5 DEVICE ID:
DIRECT INPUT 5 BIT NUMBER:
DIRECT INPUT 6 DEVICE ID:

DIRECT INPUT 6 BIT NUMBER:
UR IED 2:

DIRECT INPUT 5 BIT NUMBER:
DIRECT INPUT 6 DEVICE ID:
DIRECT INPUT 6 BIT NUMBER:
DIRECT OUT 2 OPERAND:
DIRECT OUT 3 OPERAND:
DIRECT OUT 4 OPERAND:
Signal flow between the three IEDs is shown in the figure below:
UR IED 1
In three-terminal applications, both the remote terminals must grant permission to trip. Therefore, at each terminal, Direct
Inputs 5 and 6 should be ANDed in FlexLogic™ and the resulting operand configured as the permission to trip (
setting).
