DNP3 in Geo SCADA Expert — Master Station Configuration
Key Takeaway
How to configure Geo SCADA Expert as a DNP3 master — channel setup, outstation objects, data point mapping, polling schedules, and unsolicited response handling.
Quick Answer
Geo SCADA Expert has industry-leading DNP3 master support built into the core platform. Create a DNP3 channel (serial or TCP), add outstation objects with DNP3 addresses, and create point objects mapped to specific DNP3 data object indices. See also the Geo SCADA DNP3 device setup guide for detailed configuration.
Channel Configuration
- Serial — COM port, baud rate, RS-485 mode
- TCP — Outstation IP address, port 20000
Outstation Configuration
Create a DNP3 outstation object under the channel. Set the outstation DNP3 address, master address, integrity poll interval, and event class poll rates (Class 1/2/3).
Point Mapping
- Binary Input → DNP3 Binary Input index (Object Group 1)
- Analog Input → DNP3 Analog Input index (Object Group 30)
- Counter → DNP3 Counter index (Object Group 20)
- Control output → DNP3 Binary/Analog Output index
Unsolicited Responses
Geo SCADA fully supports DNP3 unsolicited response acceptance. Enable per outstation — Geo SCADA sends the enable-unsolicited command at connection startup and processes incoming unsolicited events with the same alarm and historian handling as polled data.
Geo SCADA + SCADAPack
Geo SCADA and SCADAPack are both Schneider Electric products — they offer the tightest DNP3 integration in the market. Auto-configuration features can populate the Geo SCADA point database from SCADAPack DNP3 device profiles.
