The PLC configuration key for the entire unit is thus:
423–4M4U43
8DI8M8
8DI8M8
8DO8M8
The data lengths of the bus coupler and the modules are shown in the following
table.

Both the input and output objects are mapped to the input and output PDOs in
physical sequence. This cannot be changed. In most masters, however, alias
names can be assigned to the data, making it possible for users to select any de-
sired names for the data.
After the PLC configuration, the output bytes are assigned as shown in the follow-
ing table. See g Table 8.

Bits marked with"–" are non-information bits. They may not be used and are as-
signed the value "0". Bytes that are not used also receive the value "0".
The input bytes are assigned as shown in the following table. See g Table 9. The
diagnostic data is appended to the input data and always consists of two objects,
with a total of 8 bytes.

Bits marked with"–" are non-information bits. They may not be used and are as-
signed the value "0". Bytes that are not used also receive the value "0".
A sub-object with a length of 4 bytes is used for each module. There-
fore, the length of the process data depends on the number of mod-
ules and the type of data (input or output data) (see
the Valve Driver Data
Valve Valve
modules).
