5-122 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUALREMOTE RESOURCES CHAPTER 5: SETTINGS5Figure 5-56: Remote Resources configuration menuThe remote resources settings configure a C70 with a process bus module to work with HardFiber Bricks. Remoteresources configuration is only available through the EnerVista software, and is not available through the C70 front panel.A Brick provides eight AC measurements, along with contact inputs, DC analog inputs, and contact outputs, to be theremote interface to field equipment such as circuit breakers and transformers. The C70 with a process bus module hasaccess to all of the capabilities of up to eight Bricks. Remote resources settings configure the point-to-point connectionbetween specific fiber optic ports on the C70 process card and specific Brick. The relay is then configured to measurespecific 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 processbus module, and a specific digital core on a specific Brick. This is a necessary first step in configuring a process busrelay.• Configure the AC banks. This sets the primary and secondary quantities and connections for currents and voltages. ACbank configuration also provides a provision for redundant measurements for currents and voltages, a powerfulreliability improvement possible with process bus.• Configure signal sources. This functionality of the C70 has not changed other than the requirement to use currentsand 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'sfunctionality. These inputs and outputs are the physical interface to circuit breakers, transformers, and otherequipment. They replace the traditional contact inputs and outputs located at the relay to virtually eliminate copperwiring.• Configure shared inputs and outputs as required for the application's functionality. Shared inputs and outputs aredistinct 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 SystemInstruction Manual.
