DNP 3.0 Driver Description The DNP 3.0 Driver allows the FieldServer to transfer data to and from devices over RS-232 or RS-485 using DNP 3.0 Driver protocol. The FieldServer can emulate either a Server or Client. ∗ The following description of DNP is from the DNP User Group internet site. “The development of DNP was a comprehensive effort to achieve open, standards-based interoperability between substation computers, RTUs, IEDs

The request is with respect to inputs 20 to 29 and we will place the results of the read in the data array called DA_AI3 in positions 20 to 29. In this example the dnpSubType is not specified so the driver will report the value of the object. // Client Side Map Descriptors Map_Descriptors Map_Descriptor_Na

Vendors group data into classes based on the relationships and importance of the data. In this example you will see that only one of the Map Descriptors is active – the class data read. The remaining passive Map Descriptors are used to process the response from the class data read. The

Map Descriptor Example 6 – Read an unknown variation If the DNP device does not document the object type variation that it serves, set the variation to zero. The remote device will respond with its default variation. The problem is that the response cannot be stored using this Map Descriptor because the response will have its variation non- zero. Thus you would need to make a Server Map Descriptor for each possible variation. A b

All will work fine except when the Client polls for this data with qualifier 7. The default response will be qualifier 7 with implied index style 0. The problem is that qualifier 7 tells the Client the number of objects in the packet, but they are all assumed to be addressed sequentially from
