Compatibility of the DNP3 Driver (Interoperability)

The telecontrol protocol DNP3 was implemented in WinCC OA on level 3+ master functionality. That means that a communication is supported between WinCC OA as master and the IED (Intelligent Electronic Device) as slave. An IED is in this case more precisely an outstation.

The following object group types are supported by the WinCC OA DNP3 driver:

Binary entries and events
Counter and counter events
Analogue entries and events
Binary and analogue output states

In the following table you can find the predefined function codes and index numbers, which are used to send a request or to receive a response.

Only highlighted in bold groups are currently supported
