DNP3 parameters
MasterAddress defines the DNP3 address that this master session uses for communication.
ValMasterAddr determines if the stack should validate the source address in receive frames. DNP3
frames contain both a source address field and a destination address field. If this parameter is set to 0,
the stack does not validate the source address and thus the frames whose destination address matches
the configured slave session are accepted. If this parameter is set to 1, both the source and the
destination addresses have to match before the frame is accepted.
MasterIP-Addr defines the master's IP address.
MasterIPNetMsk determines the subnet mask that should be used to mask with the IP address.
Obj1DefVar determines the default variation for Object 1, Binary Inputs.
Obj2DefVar determines the default variation for Object 2, Binary Input Change Events.
Obj3DefVar determines the default variation for Object 3, Double Bit Inputs.
Obj4DefVar determines the default variation for Object 4, Double Bit Input Change Events.
Obj10DefVar determines the default variation for Object 10, Binary Output Status.
Obj20DefVar determines the default variation for Object 20, Binary Counters.
Obj22DefVar determines the default variation for Object 22, Binary Counter Change Events.
Obj30DefVar determines the default variation for Object 30, Analog Inputs.
Obj32DefVar determines the default variation for Object 32, Analog Change Events.
AddrQueryEnbl determines whether to enable self-address functionality on this master session (slave) as
specified by the DNP Technical Bulletin 2003-003. Self-Address Reservation. The master session (Slave)
responds to the address 0xfffc as if it had received a request for its configured address. It responds with
its own address so that the master can automatically discover the slave address.
tApplConfTout specifies how long the slave waits for the application layer confirmation from the master.
This in combination with unsolRetryDelay or unsolOfflineRetryDelay determines how frequently an
unsolicited response is resent.
ApplMultFrgRes determines if the application layer of this master session in the slave is allowed to send
multi fragment responses.
ConfMultFrag determines if application layer confirmations are requested for non-final fragments of a
multi-fragment response. Application layer confirmations are always requested for responses that contain
events.
UREnable determines if unsolicited responses are allowed. If set to 0, no unsolicited responses are
generated and requests to enable or disable unsolicited responses fail.
UREvClassMask specifies the initial or new state of the unsolicited event mask. This mask is used to
determine which event class or classes generate unsolicited responses. According to the DNP3
specification, unsolicited responses should be disabled until an Enable Unsolicited Response request is
received from the master. Thus, this value should generally be 0. However, some masters do not
24
When going down in baudrate, the size of the configuration on DNP must be considered.
