Firmware and Manual Versions
Instruction Manual
IEC 61850 and
ACSELERATOR Architect
Versions
Newer SEL-751A firmware (R102 and higher) uses a different software
library from earlier versions and is unable to process version 001 CID files.
ACSELERATOR
®
Architect
™
SEL-5032 Software generates CID files from
ICD files, so the ICD file version number and CID file version number are the
same. If downloaded to the SEL-751A, an incompatible CID file will generate
file parse errors during processing and disable the IEC 61850 protocol.
If you perform an SEL-751A firmware upgrade that spans different file
version compatibilities, the relay may be unable to process the stored CID file.
See the SEL-751A firmware upgrade instructions for CID file conversion
procedures.
See Table A.5 for compatibilities between
ACSELERATOR Architect, ICD/CID
files, and SEL-751A firmware versions.
