For AI:
Alarm Enable or Warning Enable must be set in the Object Configuration Attribute (Attribute 1).
Low/High Alarm limits (Attribute 8, 11) or Low/High Warning limits (Attribute 9, 10) must be
programmed. Differential Value (Attribute 12) must also be programmed.
For BI:
Alarm Enable must be set in the Object Configuration Attribute (Attribute 1).
Normal state must be programmed in the Object Configuration Attribute (Attribute 1)
Att XX = Attribute number, HA = High alarm, LA = Low alarm, HW = High Warning, LW = Low
Warning
The AI COS alarms will only be cleared when the point value goes below the high alarm/warning
or above the low alarm/warning limit by more than the programmed differential value (Attribute
12).
The BI COS will set the Alarm (Object Status bit 4) if COS enabled (Object Configuration Bit 0) is
set, Alarm Enabled (Object configuration bit 3) is set, and Current State (Object Status bit 6) is
different from Normal State (Object Configuration bit 1).
