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), 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. All the data are available
in channel 0.
R = data to be read from the unit
W = data to be written to the unit
(P) = writing enabled by a password
