Appendix A.16. Controlling DA Offsets

Versions of the driver prior to 1.02a used a method to calculate DA offsets that was not consistent
with the general FieldServer model. This was corrected in versions 1.02a and later. To retain the old
offset calculation, specify the ‘Application’ parameter on the connection.

Use either ‘OriginalStyle’ or ‘OrigStyle-NoLink’ (to overwrite Link Reset).

Example

// Server Side Connections

Appendix A.17. dnpIndexStyle

Normally the Server responds to requests for data using the same qualifier as the poll. Use this
parameter on a Server Map Descriptor to override the indexStyle of the qualifier in the response.
Refer to Section 5.3.6 for an example.
