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:
"
HYB POTT TX1
"
DIRECT INPUT 5 DEVICE ID:
"2"
DIRECT INPUT 5 BIT NUMBER:
"2" (this is a message from IED 2)
DIRECT INPUT 6 DEVICE ID:
"2"
DIRECT INPUT 6 BIT NUMBER:
"4" (effectively, this is a message from IED 3)
UR IED 3:
DIRECT OUT 2 OPERAND:
"
HYB POTT TX1
"
DIRECT INPUT 5 DEVICE ID:
"2"
DIRECT INPUT 5 BIT NUMBER:
"2" (this is a message from IED 2)
DIRECT INPUT 6 DEVICE ID:
"2"
DIRECT INPUT 6 BIT NUMBER:
"3" (effectively, this is a message from IED 1)
UR IED 2:
DIRECT INPUT 5 DEVICE ID:
"1"
DIRECT INPUT 5 BIT NUMBER:
"2"
DIRECT INPUT 6 DEVICE ID:
"3"
DIRECT INPUT 6 BIT NUMBER:
"2"
DIRECT OUT 2 OPERAND:
"
HYB POTT TX1
"
DIRECT OUT 3 OPERAND:
"
DIRECT INPUT 5
" (forward a message from 1 to 3)
DIRECT OUT 4 OPERAND:
"
DIRECT INPUT 6
" (forward a message from 3 to 1)
Signal flow between the three IEDs is shown in the figure below:

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 (

DIRECT ANALOGS
The direct analogs feature allows the transmission of analog values between any two UR-series relays that support the fea-
ture. The communication channel is the same as that used for the direct inputs and outputs. When the direct inputs and out-
puts and direct analog features are used together on the same channel, all UR-series relays must all be using firmware
version 5.20 or higher.
Values are transmitted as unscaled floating point numbers. The units for these values are the base units of the FlexAnalog
value (for example, volts, amperes, watts, vars, VA, etc.).
