6.3 Usage of the Layer Settings Service (LSS)
The integrated Layer Setting Services (LSS) functionality is designed according to
the CiA normative DS305V200 CANopen Layer Setting Services�
These services and protocols can be used to enquire or to change settings
of several parameters (of the physical, data link, and application layer) on a
CANopen device with LSS slave capability by a CANopen device with LSS master
capability via the CAN network�
If this is the case, the inclination sensor will be the LSS slave device and the PLC
(control) has to support the LSS master device functionality� The LSS functionality
of this series is restricted to the parameters of the application level (number of
nodes and baud rate)�
The LSS master device requests services that are performed by the inclination
sensor (LSS slave devices)� The LSS master device requests the LSS address
from the LSS slave device� The LSS address in defined in the 1018h Identity
Object and consists of a manufacturer ID, a product code, a revision number and a
series number�
After receiving this information the control can identify the inclination sensor�
The node number and baud rate can then be set� The exact procedure varies in
detail, independently of the utilised PLC tool� This object provides the general
identification of the inclination sensor�
