DNP3 parameters
28
UDPPortInitNUL defines the master's destination port to which the initial NULL
response should be sent if the channel is configured for networking. Default is 20000.
UDPPortCliMast defines the master's destination port to which responses should be
sent if the channel is configured for networking. If the parameter is set to 0, the port
number and master IP address is taken from the previous request. Default is 0. There
are specific settings for the master sessions if the master session occurs on the serial
channel or on the TCP/IP channels.
ApLayMaxRxSize specifies the maximum application fragment size received in octets.
ApLayMaxTxSize specifies the maximum application fragment size transmitted in
octets.
Master session settings for a specific communication
channel ,MST1TCP - MST4TCP
Operation determines the operation of the master session. 0 = Disabled. 1 = Enabled.
SlaveAddress defines the DNP3 address of this master session.
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.
When going down in baudrate, the size of the configuration on DNP
must be considered.
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.
