SEL-749M Relay Instruction Manual Date Code 20080918
SEL Communications Processors
SEL Communications Processor Example
Table C.6 shows the automessage (Set A) settings for the SEL
communications processor.
Table C.7 shows the map of regions in the SEL communications processor for
data collected from the SEL-749M. Use the MAP n command to view these
data.
Relay Metering Data
Table C.8 shows the list of meter data available in the SEL communications
processor and the location and data type for the memory areas within D1
(Data Region 1). The type field indicates the data type and size. The
int type is
a 16-bit integer. The float type is a 32-bit IEEE floating point number. Use the
VIE n :D1 command to view these data.
