a) Event Mask
Set the status to detect in the Event Mask
parameter.
Device Status Mask
Status group 1 Mask to 10 Mask
Ext dev status Mask
Device Diagnostic Status 0 Mask
Device Diagnostic Status 1 Mask
AO saturated Mask
AO xed Mask
When changing the conguration of the device,
Conguration Changed (0x40) Flag (refer to Table
4.7) of Device Status is set, and Cfg chng count
(refer to subsection 4.1.3 (5)) is also incremented.
Conguration changed ag detection can be
masked by the Device Status Mask, but it is
impossible to mask the Cfg chng count.
Therefore, the conguration changes to the device
are always detected as an event regardless of the
setting of the Device Status.
