4.5 LPS/LAS/LDS/SDL
The LPS, LAS, LDS and SDL lists represent network slave status. They are
maintained while in RUN mode. These lists are stored in the scanner M files:
M0 for Channel 1 and M1 for Channel 2.
The List of Projected Slaves (LPS) indicates the slaves that are configured
and stored in the EEPROM of the AS-i scanner. The LPS can be configured
using the Config port on the scanner or the G file on the SLC.
The List of Detected Slaves (LDS) indicates the slaves that are actually found
on the network, whether they appear in the LPS or not. When AS-i enters
Configuration mode, all slaves, regardless of their presence in the LPS, are
activated and listed in the LDS.
The List of Activated Slaves (LAS) contains the slaves listed in both the LPS
and the LDS. Slaves on the network are activated on AS-i power-up. Only
slaves that are present in the LPS and found on the network are activated.
Slaves must match ID and I/O codes stored in the LPS to be activated.
The Slave Delta List (SDL) contains the slaves listed in either the LPS or the
LDS, but not in both. When a slave is detected, but doesn't match any slave
listed in the LPS, it is listed in the SDL.
For each bit of the LPS, LAS, and LDS, 1 represents a present slave and 0
represents an absent slave. For SDL, 1 indicates a discrepancy between LPS
and LDS, 0 indicates a match between LPS and LDS. Refer to section 7.3 for
more information.
