3.2 Operating Mode
The F3LA01-0N module has 2 operating modes: Configuration mode and Protected
mode. Starting in Configuration mode, configuration of slaves on the ASi line are
registered to the List of Projected Slaves (LPS)
*1
. After registration completes, the
module is switched to Protected mode for normal operation. Any mismatch between the
registered LPS and actual slave configuration detected on the ASi line generates an
error.
*1 For details on LPS, see Subsection 4.1.1.

*1: The mode switch was turned from PROTECT position to CONFIG position. In this case, the module remains in Protected
mode, without transiting to Configuration mode. To switch to Configuration mode, turn the switch to the SET position for more
than 3 seconds.
*2: This indicates that an attempt to transit from Configuration mode to Protected mode has failed due to presence of a
blank slave. Although the switch is in the PROTECT position, the module remains in Configuration mode.
