5.1 Input data section in the pilot
control
The DDL address sets the position of the input data
in the data section of the DDL bus module and thus
sets the position in the address section of the pilot
control. The VS LP04 with Inputs takes up 2 bytes in
the input section of the pilot control. If the address 0
(automatic addressing) has been set, the data
section of the input data comes after the data from
the pressure control valve and before the data of the
analog module.
Only the parameter byte of the valve unit is
transmitted. The assignment of the input signals to
bit positions is listed in the following table. Byte 0
represents the first byte of the input module in the
process figure.

5.2 Output data section in the pilot
control
The DDL address sets the position of the output data
in the data section of the DDL bus module and thus
sets the position in the address section of the pilot
control. The VS LP04 with Inputs takes up according
to the valve manifold 1–4 bytes in the output section
of the pilot control. If the address 0 (automatic
addressing) has been set, the data section of the
output data comes after the data from the pressure
control valve and the valve unit.
