Figure 5–23: DUAL-CHANNEL CLOSED LOOP (DUAL-RING) CONFIGURATION
In the above application, the following settings should be applied. For UR-series IED 1:
DIRECT OUTPUT DEVICE ID:
“1”
DIRECT I/O CH1 RING CONFIGURATION:
“Yes”
DIRECT I/O CH2 RING CONFIGURATION:
“Yes”
For UR-series IED 2:
DIRECT OUTPUT DEVICE ID:
“2”
DIRECT I/O CH1 RING CONFIGURATION:
“Yes”
DIRECT I/O CH2 RING CONFIGURATION:
“Yes”
For UR-series IED 3:
DIRECT OUTPUT DEVICE ID:
“3”
DIRECT I/O CH1 RING CONFIGURATION:
“Yes”
DIRECT I/O CH2 RING CONFIGURATION:
“Yes”
In this configuration the following delivery times are expected (at 128 kbps) if both the rings are healthy:
IED 1 to IED 2: 0.2 of power system cycle;
IED 1 to IED 3: 0.2 of power system cycle;
IED 2 to IED 3: 0.2 of power system cycle.
The two communications configurations could be applied to both permissive and blocking schemes. Speed, reliability and
cost should be taken into account when selecting the required architecture.
b) CRC ALARM CH1(2)

PRODUCT SETUP
DIRECT I/O
CRC ALARM CH1(2)
The C60 checks integrity of the incoming direct input and output messages using a 32-bit CRC. The CRC alarm function is
available for monitoring the communication medium noise by tracking the rate of messages failing the CRC check. The
monitoring function counts all incoming messages, including messages that failed the CRC check. A separate counter adds
up messages that failed the CRC check. When the failed CRC counter reaches the user-defined level specified by the
CRC
ALARM CH1 THRESHOLD
setting within the user-defined message count
CRC ALARM 1 CH1 COUNT
, the
DIR IO CH1 CRC ALARM
FlexLogic operand is set.
When the total message counter reaches the user-defined maximum specified by the
CRC ALARM CH1 MESSAGE COUNT
set-
ting, both the counters reset and the monitoring process is restarted.
