DNP3 Outstation

The DNP3 Outstation driver allows Wise SCADA to act as a “substation” (RTU/Slave) and expose its data to another DNP3 Master system. Through this module, you can serve tags within SCADA to the outside world using the DNP3 protocol.

Connection Settings

Parameter	Description	Example Value
IP Address	Usually the local IP address (0.0.0.0 listens on all available network interfaces).	0.0.0.0
Port	The standard listening port for a DNP3 Outstation is 20000.	20000
Settings	Contains specific identity and timing configurations for the Outstation. Clicking this field opens the “DNP3 Outstation Dialog” for detailed settings.	[“NORMAL”,”100″,”1″,…]

DNP3 Master Dialog Ayarları

This window manages timing, data class rules, and identity settings for the Outstation.

Parameter	Description	Default / Options
Logging Level	Determines the detail level of background logs.	• NORMAL (Default) • ALL: Logs everything. • APP_COMMS: Logs the application layer only. • NONE: Does not keep any logs.
Local Address	The unique address of Wise SCADA in the DNP3 network (Outstation ID).	100
Remote Address	Only requests coming from a Master with this specific ID will be answered.	1
Keep Alive Timeout (s)	The expected TCP-level duration to verify link activity.	30
Allow Unsolicited	If checked, data is sent immediately upon change without waiting for a request from the Master.	Checked (Enabled)
Unsol Class Mask	Defines which data classes are permitted to send “Unsolicited” messages.	AllClasses: Immediate updates for Class 1, 2, 3. AllEventClasses: Event data only (Excludes Class 0). None: Disables unsolicited reporting; Polling only.
