5 Device description
The bus coupler makes it possible to control the VS via the DDL
link structure on a fieldbus. A bus coupler that complies with the
appropriate fieldbus protocol is required for this. It is not
included in this scope of delivery. In addition to connections for
data lines and power supplies, the bus coupler also enables you
to set various parameters, and permits diagnosis via LEDs. The
bus coupler can also be extended with input and output
modules. A detailed description of the bus coupler and input/
output modules can be found in the chapter "Device description"
from page 69.
The following overview outlines the entire valve system and its
components. The VS proper is described in separate operating
instructions.
