3.3.5 Process bus modules
The C70 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.
