Bits marked with "–" are filler bits. They may not be used and are assigned the value "0". Bytes that are not used also receive the value "0".

The input bytes are assigned as shown in Table 11. The diagnostic data is appended to the input data
and always consists of two objects, with a total of 8 bytes.

A sub-object with a length of 4 bytes is used for each module. Therefore, the length of the
process data depends on the number of modules and the type of data (input or output data)
(see section "6 Structure of the Valve Driver Data" on page 92 as well as the system description
of the I/O modules).
