10. Layer Setting Services (LSS)
LSS offers the possibility to change the settings of
• Node-ID
• Bit timing parameters of the physical layer (baud rate)
of a CANopen Slave.
LSS Address
An LSS Slave is identified by an LSS Address. This LSS Address consists of
• vendor-id,
• product-code,
• revision-number and
• serial-number.
These parameters are identical to the Identity-Object 1018h of the object dictionary.
Switch Mode Services
The slave accepts the LSS services only in STOPPED mode (see 9. Network Management Objects).
To configure a slave via LSS the device has to be the LSS-mode CONFIGURATION.
There are two ways to do this:
• Switch Mode Global switches all LSS Slaves between configuration and operation mode
(used for configuration of the bit timing).
• Switch Mode Selective switches exactly one LSS Slave between configuration and operation mode
(used for configuration of the node-id)
Configuration Services
Configure Node-ID
By means of this service the LSS Master configures the NMT-address parameter of a LSS Slave.
This service allows only one LSS Slave in configuration mode. The remote result parameter confirms
the success or failure of the service.
Configure Bit Timing Parameters
By means of the Configure Bit Timing Parameters service the LSS Master sets the new bit timing on a
LSS Slave.
