Date Code 20111215 Reference Manual SEL-421 Relay
IEC 61850 Communications
IEC 61850 Configuration
Ensure that you work with the appropriate version of ACSELERATOR Architect
relative to your current configuration, existing project files, and ultimate
goals. If you desire the best available IEC 61850 functionality for your SEL
relay, obtain the latest version of
ACSELERATOR Architect and select the
appropriate ICD version(s) for your needs.
ACSELERATOR Architect generates
CID files from ICD files so the ICD file version
ACSELERATOR Architect uses
also determines the CID file version generated.
As of this writing,
ACSELERATOR Architect comes with two versions of the
ICD file for use with the SEL-421-2 or SEL-421-3 on new or existing
projects. These versions are:
➤ 002 (SEL-421-2/-3 8-Pushbutton Model): This file is
compatible with Ethernet card firmware R107 to R112 and the
8-pushbutton model of the SEL-421.
➤ 002 (SEL-421-2/-3 12-Pushbutton Model): Identical in
content to the file above, with additional logical nodes for extra
pushbuttons made accessible in SEL-421 R123 or higher
firmware. Select this file to enable access to these additional
logical nodes when using the 12-pushbutton model of the
SEL-421.
Note: Using this file with SEL-421 R122 and lower firmware
may cause unexpected behavior.
CID File Conversion
If you attempt to download a version 001 CID file to a relay with Ethernet
card firmware R107 to R112,
ACSELERATOR Architect will offer to make the
file compatible with version 002. If you agree,
ACSELERATOR Architect will
modify the existing CID file so that the relay can successfully process it. If
you decline, the relay will cancel your request to download the CID file to the
relay.
Similarly, if you attempt to download a version 002 CID file to a relay with
Ethernet card firmware R113 or higher,
ACSELERATOR Architect will offer to
convert the file to version 003. Once converted, there will be no difference
between version 002 and 003 except for the file version number stored in the
CID file. If you agree,
ACSELERATOR Architect will change the CID file
version so that the relay can successfully process it. If you decline, the relay
will cancel your request to download the CID file to the relay. Note that the
version 003 file created this way for the SEL-421-2 or SEL-421-3 is
completely different from the version 003 file intended for the SEL-421-4 or
SEL-421-5 relay with firmware R300 or higher. This conversion is the only
method
ACSELERATOR Architect supports to download a CID file to a relay
with Ethernet card firmware R113 or higher. Do not attempt to download the
version 003 file supplied for the SEL-421-4/-5 in the default IED Palette to an
SEL-421-2 or SEL-421-3.
ACSELERATOR Architect will only prompt you to perform this conversion
when it recognizes that it is trying to download an unsupported CID file to a
relay. This is done on a per-file basis. That is, there is no option to do a batch
conversion of all CID files in a project.
See Table 8.7 for a summary of the logical nodes provided with each ICD file
version.
NOTE: If left unmodified,
downloading the file will cause
CID file parse errors and
disable the IEC 61850 protocol.
