Is there an option in DNP3 driver (In fact at TCP level) to make it listen on a certain (usually 20000 for DNP3)? In era of IoT devices, most devices are sleeping devices, they wake up usually once a day and push data to DNP3 Master (PI), however DNP3 PI collector doesn't support this model. As an enduser I would like to utilize this mode of operation at our plant. FYI, there are other products e.g. Citect SCADA and ClearSCADA use two separate ports for Inbound and outbound DNP3 traffic to use the both modes simultaneously.

Create some way to configure PI Points belonging to a DNP3 interface instance such that the interface only requests data for a single class (Class 1/Class 2/Class 3) and not all three? Essentially, an event scan that will request one specified Class 1, 2, or 3 data from the RTU.

DNP3 - add functionality to allow outputs for binary and possibly other object groups/variations.
