Information General

Communication Driver Name: DNP3
Current Version: 9.2
Implementation DLL: T.ProtocolDriver.DNP3V2.dll
ProtocolP: DNP3.0 Master standard protocol
Interface: TCP/IP
Description: The driver is used for communication with data acquisition devices (IED's) that use the DNP3 Level 3 protocol. Communication can be done through a multipoint serial channel or using local Ethernet network and TCP-IP protocol, in which case each IED has an IP address.
IEDs types supported: Any compatible IED DNP2
Communication block size: Maximum 250 bytes, FT 1.2 format
Protocol Options: "LinkConfirm" mode and end of the master station.
Threading: User configurable; default is five threads for the cda network node.
Max number of nodes: user-defined
PC Hardware Requirements: Standard PC Ethernet interface board
PC Software Requirements: ActionNET system.

DNP3 Channel Creation

To create a channel using the DNP30 protocol, go to Edit>Devices>Channel, and in Installed protocols, choose DNP30 L3-V2 - Master Standard Protocol.

After this choice, a window will be displayed to enter the channel name and choose the mode. You can choose TCP-IP communication mode (CustomTCPIP) or Serial communication mode (CustomSerial).

Depending on this choice, some other settings will be specific to each of these modes. In the next items, these settings will be detailed.
