Data to be
transferred over
the serial bus
In addition to the event code data transfer, the
input data (I data), output data (O data), set-
ting values (S), memorized data (V data) and
some other data can be read from the relay
module over the serial communication bus.
Further, part of the data can be changed over
the SPA bus by separate commands. All data
information is available in channel 0.
