DNP3 Outstation
In Outstation mode inSCADA lets external masters connect and read data from it. The mode is typically used to:
- present data over DNP3 to a higher-level SCADA system
- pass data up to a control centre
- share data between separate inSCADA installations
Configuration
Section titled “Configuration”Connection
Section titled “Connection”| Parameter | Example | Description |
|---|---|---|
| Protocol | DNP3 Slave | The protocol |
| Port | 20000 | The listening port (for incoming connections) |
Device
Section titled “Device”In outstation mode the two address roles swap over:
| Parameter | Description |
|---|---|
| Local Address | The outstation’s own DNP3 address |
| Remote Address | The DNP3 address of the master that will connect |
Frame and variable
Section titled “Frame and variable”Frames and variables are defined exactly as in master mode. The values of the variables you define are presented to the connected master as DNP3 objects.
A typical deployment
Section titled “A typical deployment”Here inSCADA collects data from field devices over several different protocols and presents it upwards as a DNP3 outstation, acting as a protocol gateway.
