messages for SEL devices in ACSELERATOR Architect. See the
ACSELERATOR Architect instruction manual or online help for more
information.
Each IEC 61850 GOOSE sender includes a text identification string (GOOSE
Control Block Reference) in each outgoing message and an Ethernet multicast
group address. Devices that receive GOOSE messages use the text
identification and multicast group to identify and filter incoming GOOSE
messages.
CCIN (Communications Card Input) bits are control inputs that you can map
to GOOSE receive messages using the
ACSELERATOR Architect software. See
the CCINnn bits in Table 8 .15 for details on which logical nodes and names
are used for these bits. This information can be useful when searching through
device data with MMS browsers. If you intend to use any SEL-421 CCIN bits
for controls, you must create SEL
OGIC
®
equations to define these operations.
The CCIN Logical Nodes only contain CCIN status, and only those CCINs
that are part of the SER dataset will be able to track CCIN transitions (via
reporting) between LN data update scans.
File Services
The Ethernet File System allows reading or writing data as files. The File
System supports FTP and, for the SEL-421, the Shared Memory File Transfer
service. The File System provides:
➤ A means for the device to transfer data as files.
➤ A hierarchal file structure for the device data.
SCL Files
Substation Configuration Language (SCL) is an XML-based configuration
language used to support the exchange of database configuration data between
different tools, which may come from different manufacturers. There are four
types of SCL files:
➤ IED Capability Description file (.ICD)
➤ System Specification Description (.SSD) file
➤ Substation Configuration Description file (.SCD)
➤ Configured IED Description file (.CID)
The ICD file describes the capabilities of an IED, including information on
LN and GOOSE support. The SSD file describes the single-line diagram of
the substation and the required LNs. The SCD file contains information on all
IEDs, communications configuration data, and a substation description. The
CID file, of which there may be several, describes a single instantiated IED
within the project, and includes address information.
Reports
SEL-421 supports buffered and unbuffered report control blocks in the report
model as defined in IEC 61850-8-1:2004(E). The predefined reports shown in
Figure 8.1 are available by default via IEC 61850.
