D.5
Date Code 20130214 Instruction Manual SEL-2414 Transformer Monitor
DNP3 Communications
DNP3 in the SEL-2414
In response to the delay measurement function code, the SEL-2414 will return a
time delay accurate to within 50 milliseconds.
Object List
Table D.5 lists the objects and variations with supported function codes and qual-
ifier codes available in the SEL-2414. The list of supported objects conforms to
the format laid out in the DNP specifications and includes both supported and
unsupported objects. Those that are supported include the function and qualifier
codes. The objects that are not supported are shown without any corresponding
function and qualifier codes.
