3.3.5 Process bus modules
The N60 can be ordered with a process bus interface module. The module interfaces with the HardFiber Process Bus
System, or HardFiber Brick, allowing bidirectional IEC 61850 fiber optic communications with up to eight HardFiber Bricks.
The HardFiber system integrates seamlessly with the existing UR-series applications, including protection functions,
FlexLogic, metering, and communications.
This process bus system offers the following benefits:
•
Reduces labor associated with design, installation, and testing of protection and control applications using the UR by
reducing the number of individual copper terminations
•
Integrates seamlessly with existing UR applications, since the IEC 61850 process bus interface module replaces the
traditional CT/VT modules
•
Communicates using open standard IEC 61850 messaging
For details on the HardFiber system, see its Instruction Manual.
