Notes
This is a shutter type of filter for DNP3 point change detection that is
implemented in the code, per DNP3 specifications. Refer to Section 6.3.4.DNP3
Polled Object Parameters –Push-Back Messages (Section b) It is a WORD
denominated in milliseconds. Value: 10 to 32000; default is 250ms. The filter
value is set in the COMMREQ instruction when the station is parameterized.
Each master station communicating with the Outstation must have a unique LLA
address. The DNP3 code manages the connections using the LLA address and as
such the Outstation cannot handle duplicate LLA Source (Master Station)
addresses.
The EDS001 module will not start the DNP3 Outstation portion of the application
if NO network is connected to the EDS001 module. This can be worked around
by using a Loopback style of RJ-45 Ethernet connector to indicate a network
presence to the EDS001 module.
