APPENDIX H: SEL-2020 CONFIGURATION AND FAST
OPERATE COMMANDS
OVERVIEW
This appendix describes the binary commands supported on SEL-2020 master ports using SEL
protocol with FAST_OP=Y. There are three types of commands supported: device definition,
Fast Operate configuration, and Fast Operate commands. See Application Guide AG95-10:
Configuration and Fast Meter Messages to see how these commands relate to the general SEL
binary command definitions.
DEVICE DEFINITION
The device definition can be found in response to the A5C0h command. It will have the
following format:
A5C0 Command
0E Message length (14 bytes)
03 Support three protocols
00 Does not support Fast Meter messages
00 Does not support status flag commands
0100 Supports SEL protocol with Fast Operate commands
0001 Supports LMD protocol without Fast Operate commands
0002 Supports Modbus protocol
00 Pad byte
xx Checksum
FAST OPERATE CONFIGURATION
The Fast Operate Configuration information is returned in response to the A5CFh command. It
has the following format:
A5CF Command
0C Message length (12 bytes)
10 16 ports in SEL-2020
10 16 breakers per port supported
10 16 remote bits per port supported
A5E5 Fast Operate command to open a breaker
A5E6 Fast Operate command to close a breaker
A5E8 Fast Operate command to clear a remote bit
A5E7 Fast Operate command to set a remote bit
