Data to be
transferred over
the serial bus
In addition to the spontaneous data transfer the
SPA bus allows reading of all input data (I-data)
of the module, setting values (S-values), infor-
mation 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.
