Figure 5-91: Remote Resources configuration menu
The remote resources settings configure a F35 with a process bus module to work with HardFiber Bricks. Remote
resources configuration is only available through the EnerVista software, and is not available through the F35 front panel.
A Brick provides eight AC measurements, along with contact inputs, DC analog inputs, and contact outputs, to be the
remote interface to field equipment such as circuit breakers and transformers. The F35 with a process bus module has
access to all of the capabilities of up to eight Bricks. Remote resources settings configure the point-to-point connection
between specific fiber optic ports on the F35 process card and specific Brick. The relay is then configured to measure
specific currents, voltages and contact inputs from those Bricks, and to control specific outputs.
The configuration process for remote resources is straightforward and consists of the following steps.
•
Configure the field units. This establishes the point-to-point connection between a specific port on the relay process
bus module, and a specific digital core on a specific Brick. This is a necessary first step in configuring a process bus
relay.
•
Configure the AC banks. This sets the primary and secondary quantities and connections for currents and voltages. AC
bank configuration also provides a provision for redundant measurements for currents and voltages, a powerful
reliability improvement possible with process bus.
•
Configure signal sources. This functionality of the F35 has not changed other than the requirement to use currents
and voltages established by AC bank configuration under the remote resources menu.
•
Configure field contact inputs, field contact outputs, RTDs, and transducers as required for the application's
functionality. These inputs and outputs are the physical interface to circuit breakers, transformers, and other
equipment. They replace the traditional contact inputs and outputs located at the relay to virtually eliminate copper
wiring.
•
Configure shared inputs and outputs as required for the application's functionality. Shared inputs and outputs are
distinct binary channels that provide high-speed protection quality signaling between relays through a Brick.
For additional information on how to configure a relay with a process bus module, see the HardFiber Process Bus System
Instruction Manual.
