### HelicsWin.Net variables and values

The internal data structure of the HWN databases differs from that of the TESSy database. The variable names and code values stored in the database are also different. The internal code values of HWN are stored in the Reference.mdb database.

For a description of the HWN variable names and the corresponding TESSy variables, see the HelicsWin.Net protocols.

The following screenshot shows the internal code values in HWN that are stored in the ID field in the tables in Reference.mdb
