CHAPTER 5: SETTINGS
Direct input and output settings are similar to remote input and output settings. The equivalent of the remote device name
strings for direct inputs and outputs is the
messages. All UR-series IEDs in a ring need to have unique numbers assigned. The IED ID is used to identify the sender of
the direct input and output message.
If the direct input and output scheme is configured to operate in a ring (
is "Yes"), all direct output messages are received back. If not, the direct input/output ring break

over direct inputs and outputs must be set to the same data rate. UR-series IEDs equipped with dual-channel
communications cards apply the same data rate to both channels. Delivery time for direct input and output messages is
approximately 0.2 of a power system cycle at 128 kbps and 0.4 of a power system cycle at 64 kbps, per each "bridge."
