CHAPTER 5: SETTINGS
In this architecture, Devices 1 and 3 do not communicate directly. Therefore, Device 2 must act as a 'bridge'. The following
settings are applied:
UR IEC 1:
: "HYB POTT
DIRECT OUT 2 OPERAND
: "2"
DIRECT INPUT 5 DEVICE ID
DIRECT INPUT 5 BIT NUMBER
: "2"
DIRECT INPUT 6 DEVICE ID
DIRECT INPUT 6 BIT NUMBER
UR IED 3:
: "HYB POTT
DIRECT OUT 2 OPERAND
: "2"
DIRECT INPUT 5 DEVICE ID
DIRECT INPUT 5 BIT NUMBER
: "2"
DIRECT INPUT 6 DEVICE ID
DIRECT INPUT 6 BIT NUMBER
UR IED 2:
: "1"
DIRECT INPUT 5 DEVICE ID
DIRECT INPUT 5 BIT NUMBER
: "3"
DIRECT INPUT 6 DEVICE ID
DIRECT INPUT 6 BIT NUMBER
: "HYB POTT
DIRECT OUT 2 OPERAND
: "DIRECT INPUT
DIRECT OUT 3 OPERAND
: "DIRECT INPUT
DIRECT OUT 4 OPERAND
The figure shows the signal flow among the three IEDs.
