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
DIRECT OUTPUT DEVICE ID
setting, which identifies the relay in all direct output
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 (
DIRECT I/O CH1 RING CONFIGURATION
or
DIRECT I/O
CH2 RING CONFIGURATION
is “Yes”), all direct output messages are received back. If not, the direct input/output ring break
self-test is triggered. The self-test error is signaled by the
DIRECT RING BREAK
FlexLogic operand.
Select the
DIRECT I/O DATA RATE
to match the data capabilities of the communications channel. All IEDs communicating
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."
