table_no: Integer – The number for the table from which to collect data.
record_no: Integer – The record number where data collection will start. All
records following this record number will be included in the collection.
Therefore, if the record number is set to 0, all records in the table will be
collected. In addition, if the record number specified does not exist in the
datalogger, all existing records from the oldest to the newest will be returned.
However, if the record number is set to a negative number, only the most
recent record in the table will be collected. There is not a way to specify and
collect a single record from a table using this command unless that record is the
most recent record in the table.
