Where a third-party server uses the DNP3 protocol to retrieve data from Geo SCADA Expert, the Geo SCADA Expert system acts as a Slave Outstation.
For this scenario, within Geo SCADA Expert you need to configure (as appropriate to the type of communications being used):
- At least one DNP3 Slave Direct Channel and/or DNP3 Slave PSTN Channel
- At least one DNP3 Slave Direct Outstation Set and/or DNP3 Slave PSTN Outstation Set
- One DNP3 Slave Direct Outstation or DNP3 Slave PSTN Outstation for each DNP3 outstation that the Geo SCADA Expert server will act as (Geo SCADA Expert may be configured to appear as more than one) outstation.
- Filtered Value Maps to map values in the Geo SCADA Expert database that will be read by the third party DNP3 master.
The diagram below shows a third party server acting as a DNP3 master to Geo SCADA Expert:
