Serial communica-
tion parameters
Apart from the event codes the substation level
data communicator is able to read, over the
SPA-bus, all input data (I-data) of the module,
setting values (S-data), information recorded in
the memory (V-data), and some other data.
Further, part of the data can be altered by
commands given over the SPA-bus.
