The data type of each record in a datalog file can be of any type. However, the data type varies depending on how you logged the data to the datalog file.

Table 21. Datalog Data Type by Creation Method
Creation Method Data Type
Datalog file created using the Write Datalog function The data type matches the data LabVIEW wrote to the datalog file.
Datalog file created using front panel data logging The data type is a cluster of two clusters.
  1. The first cluster contains a time stamp. The timestamp comprises the following:
    • A 32-bit unsigned integer that represents seconds
    • A 16-bit unsigned integer that represents milliseconds elapsed from LabVIEW system time
  2. The second cluster contains the front panel data. The front panel data cluster contains the data types that correspond to all front panel controls and indicators in their respective tabbing order.
