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"
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.
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.
