NV
Name SNVT
ID Comments
DL_Clear_1 95 Setting this network variable to

tracking if set to FALSE
DL_Level_Full_1 21 Emitted as the event log fills depending on Alarm at
Percent Full configuration property. An external device

Each event contains the following fields:
Event Num (1 byte) The enumerated value associated with this event as
defined in
dmobj.h
.
Severity (1 byte) The user defined severity of the event. This value is kept
only in the event list and is intended for use as
documentation date, i.e., the value has no effect on the
event. The default is 0 for all events. This value may be
changed using the Event List Editor, described later in
this chapter.
Send Async (1 byte) A
TRUE
or
FALSE
value which determines whether the
event will be sent on the DM_Event network variable
when the event is generated. If set to
FALSE
, generated
events will be logged in the Device Manager event log (see
Event Log later in this chapter) but not sent on the
DM_Event network variable. If set to TRUE, generated
events will be logged in the event log and sent on the
Device Manager network variable. The default is FALSE
for all events except
DMEVNT_DEVICE_COMMISSIONED
, for
which the default is
TRUE
. This value may be changed
using the Event List Editor described later in this chapter.
Parameter (2 bytes) The parameter returned by this event, if this event
returns a parameter.
Text (30 bytes) The text associated with this event. This value may be
changed using the Event List Editor described later in this
chapter.
See File Transfer later in this chapter for details on how to read the event log.
