Logging

The

Configuration.DataLogFile

table contains the file selection string. Options

include the following:

The desired Data Log file name from which to return records

Alternately, ‘allfiles’, to return records from all Data Log files

An appended chronology switch:

‘/r’ to begin with the most recent record

‘/f ‘to return the oldest record first (default if no chronology switch is
appended)

For example, writing the string ‘DataLog_20130112_0630_11/r’ selects the file
DataLog_20130112_0630_11. Successive reads of the

LoggingResults.Data_Log

table return sequential data log records, starting with

the last record.

The

LoggingResults.Data_Log

table contains the most recent record read from

the selected data log file, and contains the following elements.

Element 0 indicates the type of record. Options are:

0 = No record returned

1 = Parameter values

2 = Parameter index values

3 = Log file not found

Element 1 returns a unique record ID or the total number of records,
depending on the value of Element 0.

Elements 2…5 return the date and time stamp of the record

Elements 6…34 return parameter values or parameter index values
depending on the value of Element 0.

Parameter index values are associated with parameter tag names as listed in
