Appendix A. Sample Program Table

Structure

The table structure of a PakBus datalogger is given in the example below. This

example shows a datalogger with two user defined tables plus the Status table

and Public or Inlocs table. The second table in the example below contains

three records and the third table contains four records. Both the Status table

and Public or Inlocs table will always return the most recent records and will

not contain any historical data records.

The first table is the Status table, which shows the status of the datalogger.

The Public or Inlocs table contains all public variables or input locations. All

other tables found in the datalogger are created and defined by the user in the

datalogger program. The tables in a PakBus datalogger will always contain a

record number and timestamp followed by the data fields.
