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

Connections
Port	,Baud	,Parity	,Protocol	,Application
P8	,9600	,None	,DNP	,OriginalStyle

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.
