If the Node-ID was recently changed with a Configure Node-ID command, the original Node-ID will continue to be returned until the next power on reset. A value of FFh is returned if the Node-ID is not configured … this is only possible if the slave is in ‘LSS Init State’.

3.5Identification Services

This protocol is used to implement the 'LSS Identify Remote Slaves' service.

3.5.1LSS Identify Remote Slaves

By means of this service, the LSS Master requests all LSS slaves, whose LSS address meets the LSS_Address_sel to identify themselves by means of the 'LSS Identify Slave' service.

LSS_Address_sel consists of a fixed Vendor ID and Product Code and a span of revision and serial numbers. This service goes unconfirmed.
