Configuring a DNP3 Channel

You configure DNP3 Channels in the Geo SCADA Expert database to represent the physical communication mechanisms between Geo SCADA Expert and the DNP3 outstations on your system. The Geo SCADA Expert DNP3 Driver supports these types of DNP3 Channel:

DNP3 Direct Channel

Used when Geo SCADA Expert is the master DNP3 device and connects to the DNP3 outstations directly (for example by serial cable, IP network, or radio).

If your system setup allows, you can configure outstations that are connected via direct channels to use PSTN as a backup means of communication if the direct channel fails.

DNP3 PSTN Channel

Used when Geo SCADA Expert is the master DNP3 device and connects to the DNP3 outstations using dial-up modems.

DNP3 Slave Direct Channel

Used when Geo SCADA Expert is configured as a slave DNP3 device and other DNP3 devices connect to Geo SCADA Expert directly (for example by serial cable, IP network, or radio).

DNP3 Slave PSTN Channel

Used when Geo SCADA Expert is configured as a slave DNP3 device and other DNP3 devices connect to Geo SCADA Expert using dial-up modems.

You specify the properties of a DNP3 channel using the fields on the DNP3 Direct Channel, DNP3 PSTN Channel, DNP3 Slave Direct Channel, or DNP3 Slave PSTN Channel Form, as appropriate.

Each Form has several tabs.

This section covers configuration of DNP3-specific properties on the Scan Parameters tab.

For each type of DNP3 Channel, you use the Scan Parameters tab to:

For DNP3 Direct Channels, you also use the Scan Parameters tab to:

Properties on the other tabs are common to channels on many advanced drivers—for information, see Tabs on Channel Forms.

For information on the minimal amount of configuration that you can undertake to produce a functional DNP3 Channel in Geo SCADA Expert, see Minimum Configuration.
