Data to be trans-
ferred via the fibre-
optic serial bus
In addition to the spontaneous data transfer the
SPA bus allows reading of all input values (I-
values), setting values (S-values), information
recorded in the memory (V-values), and some
other data. Further, part of the data can be
altered by commands given over the SPA bus.
