Where Geo SCADA Expert uses the DNP3 protocol to retrieve data from its outstations, the Geo SCADA Expert system acts as a DNP3 Master.
For this scenario, within Geo SCADA Expert you need to configure (as appropriate to the type of communications being used):
- At least one DNP3 Direct Channel and/or DNP3 PSTN Channel
- At least one DNP3 Direct Outstation Set and/or DNP3 PSTN Outstation Set
- One DNP3 Direct Outstation or DNP3 PSTN Outstation for each DNP3 outstation with which the Geo SCADA Expert server is to communicate.
- A DNP3 Point for each point in the DNP3 outstations.
In the diagram below, Geo SCADA Expert is using the DNP3 protocol to communicate with three DNP3 outstations:
