"Value" section (value)
This section is used to transfer numerical values. The significance and function of the numerical values
are defined by the sections described above.
Structure of the input data (PDI)
In transfer mode, the purpose of the input data (PDI) is to confirm the transfer that has taken place
or to output the requested value. To do this, the information that was transferred via "valve mode",
"channel", "transfer control", "addressed target" and "index" to the output data is returned to the
corresponding positions in the input data.
The "valve state" section shows the information described in section (
è
3.5.2.2 Structure of the input
data (PDI)).
