OpenLNS Programmer's Reference 870
The possible values for this
parameter, which is contained in
the ConstEventSyncModes
constant, are as follows:
0 lcaEventNoSyncMode
Disables automatic event
synchronization.
If missed events are enabled, an
OnMissedEvent will be sent for
every missed event, including the
periodic ping event.
Missing a ping event will cause an
OnMissedEvent to be sent with the
isUnrecoverable parameter set to
TRUE, and the numMissedEvents
parameter set to 0.
1 lcaEventAutoSyncMode
Enables automatic event
synchronization.
Recovery will be done
automatically within calls to the
DoEventSync method.
An OnMissedEvent will only be
sent if the Server's "previously sent
events" buffer overflows. This
buffer can hold up to 20 events. If
the remote is out of contact while
more than 20 events were
generated for it, an OnMissedEvent
will be generated with the
isUnrecoverable parameter set to
TRUE and the numMissedEvents
parameter equal to some positive
integer. This lets the remote
device know that it should flush
out any caches it maintains via
event updates.
2 lcaEventHostSyncMode
This is not currently supported.
delay The delay (in milliseconds) prior to
delivering a resynchronization
request. The default value is 0.
You shoud set the delay parameter
when there are more than a few
remote event subscribers to
prevent the network from being
flooded with resynchronization
