DNPR Driver

The DNPR driver allows Plant SCADA to communicate with devices that support DNP3 protocol subsets Level 1 and Level 2. Some level 3 features are also supported.

Citect SCADA 7.20 or later (or a later version of Plant SCADA) is required to use the DNPR Driver.

For an explanation of the protocol subsets, see The DNP 3.0 Protocol.

Note: To successfully implement the DNPR driver, it is recommended that you are familiar with the terminology and methods involved with configuring devices for DNP 3.0 communication.

Communication can take place over serial (RS232) or TCP/IP transport. The type of devices the driver will communicate with include:

• RTUs

• IEDs

• PLCs.

Note: With the release of version 7.20, Plant SCADA supports the retrieval of time-stamped data directly from field devices. This capability is enabled by the Driver Runtime Interface (DRI), a component of Plant SCADA that is used by the DNPR driver to directly update time-stamped digital alarms, time-stamped analog alarms and event-based trends. For more information, see the topic Retrieving Time-stamped Data from Field Devices in the main Plant SCADA help.
