2 Access over CANopen

2.9 The device Layer Setting Services (LSS)

The device supports LSS according the DSP 305. The necessary data to perform the LSS switch mode selec-
tive service can be read from the name plate of the device (see figure 2).
The LSS offer the possibility to change the node ID bit-timing of the CAN module and the inquiry of the
LSS address (via remote access).
The LSS functionality is modelled using two objects:
• LSS master
The module, that configures other modules via a CAN network, is called the LSS master. There may be
only one LSS master in a network.
• LSS slave
The module, that is configured by the LSS master via a CAN Network, is called the LSS slave. Our
valves and pumps act as LSS slaves. The LSS slave can be uniquely addressed by its LSS address.
There is no other module in the world with the same LSS address, which is assigned to the module by
the manufacturer.
Information about the LSS address is available from the name plate of the device or can be inquired by a LSS.
The LSS slave can be in two states, either in the Operation Mode or in the Configuration Mode. The LSS are
activated when the LSS slave is in Configuration Mode. This ensures that only the desired module listens to
the LSS.
The LSS are used to set the node ID and baud rate of the CANopen device. Before a configuration over LSS
can take place, the slaves need to be in configuration mode. In configuration mode, protocols such as the
configure node ID protocol can be used.
