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.

Note: It is recommended that you use the DNPR driver with a version of Plant SCADA that is fully supported in accordance with AVEVA's Software Support Lifecycle and Retirement Policy. The driver will work with Citect SCADA 7.20 or later (or a later version of Plant SCADA), however it will not be fully tested or supported on these earlier versions. Search the AVEVA Support Site Technology Matrix to determine the support status for your current version of Plant SCADA.

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.
