entries in the log file.
<UCPTmodificationNumber>
A counter indicating the number of times the log file has
been modified. The counter is not increased when data is
added to the end of the log, but only if some modifications
are made to the existing data.
<UCPTlogLevel>
The volume of the log file that has been consumed, as a
percentage. For example, the value 90.0 indicates that the
log is 90% full.
<UCPTtotalCount>
This property contains the total number of entries contained
in the data log read by the function.
The Read function returns an <Item> element describing each log entry that met the selection criteria
you defined in the input parameters. The following table lists the properties within each of these
elements.
Property Description
<UCPTname>
The name of the data point in the following format:
<network/channel/device/functional block/data point>.
<UCPTaliasName>
The default or user-defined nickname provided for the data point.
<UCPTlastUpdate>
A timestamp indicating the time that the log entry was made. This
timestamp is shown in local time, with an appended time zone
indicator showing the difference between local time and UTC.
For more information on this, see
Local Times and Coordinated
Universal Time.
<UCPTvalue>
The value the data point was updated to when the log entry was
made. The value may be presented in the following two
LonFormats:
LonFormat="#<programID>[scope].<data type>". The
format is specified by the data type defined for the data point.
For a SNVT_switch data point, this value could be 100.0 1 or
0.0 0, for example.
LonFormat="UCPTvalueDef". The value defined for the data
point by a preset. For a SNVT_switch data point, this value
could be ON or OFF, for example. If a preset is not defined
for the data point, this value is AL_NUL.
<UCPTunit>
The unit type of the data point.
<UCPTpointStatus>
The status the data point was updated to when the log entry was
made.
<UCPTpriority>
The priority level currently assigned to the data point (0-255).
The priority level of a data point determines which applications
can write to its value. You can modify the value of this property
with the Write or ResetPriority functions.
