AS-i 3.0 Command Interface
Commands of the Command Interface
4.3.3.12 Commands 11 and 13:
read "Current safety monitor shutdown-history"
Information
This command is only available with safety monitors, version GII "ext. mode" (in stain-
less steel housing).
See <table 4-33> for an overview of the acyclic transfer commands and the supported
monitor types.
In the case of a second generation safety monitor, the shutdown-history can be
read additionally to the safety unit diagnostic.
If an OSSD abandons the state green, the states of all devices are hold on at this
moment. Therefore it is possible to detect the cause for the turning-off läter.
If there has been no turning-off of the related OSSD since the start, all devices
are grey.
If the slave-/monitor address is "0", the internal monitor is activated, otherwise the
external one.
