Data Access
you can use the QUIT command to log out before closing the Telnet
connection.
Telnet to the SEL-2701
For the third connection type, use the TCP/IP port number (see setting
T2PNUM in Table 3.6 on page 3.7 in Section 3: Settings and Commands), to
Telnet directly to the SEL-2701. This is useful for operating the SEL-2701
user interface to collect diagnostic data and perform other operations with the
SEL-2701. Use the QUIT command to log out and end the Telnet session.
UCA2
The SEL-2701 provides the unique capability to allow both protective relays
and other IEDs to integrate into UCA2 systems without the need to install a
separate protocol converter and Ethernet network interface on each device.
See Section 3 for a description of UCA2 interface settings.
GOOSE
The SEL-2701 can generate and receive GOOSE messages. Acting as a single
source and recipient of GOOSE messages, the SEL-2701 listens for and
utilizes data in GOOSE messages from as many as eight GOOSE senders. For
a description of SEL-2701 settings for outgoing GOOSE messages and to map
incoming messages to specific control bits, see Section 3. The SEL-2701
communicates data from incoming GOOSE messages to the SEL-2030 as 64
incoming control points (CCIN1–CCIN64). The SEL-2701 automatically
maps the outgoing control points CCOUT1–CCOUT64 to the first 64
outgoing GOOSE message bits.
EXAMPLE 4.1 Outgoing Control Points
The SEL-2701 uses outgoing control points to generate and send
outgoing UCA2 GOOSE messages. To send the state of the SEL-2030
ALARM bit as User ST Bit 1 in the outgoing GOOSE message, set the
SEL-2030 CCOUT1 setting as shown below. The example assumes
that your SEL-2701 is installed on Port 17.
Enter the SEL-2030 SET O 17 command and set CCOUT1.
CCOUT1=ALARM
If something either activates or deactivates the SEL-2030 ALARM,
the SEL-2701 generates and transmits a new GOOSE message
containing a bit pair representing the new state of ALARM. If the
state changes to on, the bit pair is 10. If the state changes to off, the
bit pair is 01.
EXAMPLE 4.2 Incoming Control Points
In this example, the incoming GOOSE Monitor 1 User ST Bit Pair 1 will
control the Port 3 Remote Bit RB1. This example illustrates settings
when the SEL-2701 is installed on Port 17 (Card 1). The SEL-2701
settings used to direct information from the incoming GOOSE
message to the SEL-2030 and the Port 3 logic settings are shown
below.
Port 17, SEL-2701 Settings
CTRLB1 = 1:0
CTRLB2 = 1:33
Port 3 Logic Settings
SRB1 = 17:CCIN2 * !17:CCIN1 + 17:CCIN1
CRB1 = !17:CCIN2 * !17:CCIN1
In this example, CTRLB1 is set with the special GOOSE Bit 0. Bit 0 is
an alarm that turns on when the hold time for the previous GOOSE
message has expired and during GOOSE ID resolution. This bit is used
