Firmware and Manual Versions
Instruction Manual
version number and CID file version number are the same. If downloaded to
the Ethernet card, an incompatible CID file will generate file parse errors dur-
ing processing and disable the IEC 61850 protocol.
If you perform an Ethernet card firmware upgrade that spans different file ver-
sion compatibilities, the relay may not be able to process the stored CID file.
See the Ethernet Port Firmware Upgrade Instructions in the SEL-400 Series
Firmware Upgrade Instructions for CID file conversion procedures.
See Table A.4 for compatibilities between
ACSELERATOR Architect, ICD/CID
file, and Ethernet card firmware versions.
