Points Used on DNP3 Outstations
This section provides information about DNP3 string and ‘Generic’ points (see DNP3 Master Configuration). If your system is running a DNP3 Extension Driver, other types of DNP3 point might be available. For information about non-generic DNP3 points, see the relevant DNP3 extension driver guide.
This section covers points on DNP3 outstations for which Geo SCADA Expert is the DNP3 master. (DNP3 Slave Outstations use Filtered Value Maps rather than points to map point properties into the Slave’s memory, so that those properties can be accessed by the DNP3 protocol. For further information, see Configuring Value Maps in the Geo SCADA Expert Guide to Core Configuration, and see Define the Filtered Value Map Locations.)
A DNP3 point is defined by its Point Type (for example, analog input, binary output, counter) and Point Number (address). DNP3 Direct Outstations and DNP3 PSTN Outstations support a combination of the point types that are listed below. You configure the properties for each point type using the fields on the appropriate DNP3 Point Form.
This section covers the configuration of properties that are common to the DNP3 points that are supported by the Geo SCADA Expert DNP3 driver. It includes information on how to:
- Configure General Point Properties
- Configure Logged Data Properties
- Specify Whether an Output Point is Controlled by Geo SCADA Expert
- Specify which Outstations are Integrity Polled after a Successful Control
- Configure the DNP3-Specific Control Properties on DNP3 Output Points.
For configuration properties specific to a particular DNP3 point type, also see the following sections:
- DNP3 Analog Input Point—see Configuring DNP3 Analog Points.
- DNP3 Analog Output Point—see Configuring DNP3 Analog Points.
- DNP3 Binary Input Point—a 1-, 2-, or 3-bit point that indicates the status of an item of plant, where the plant may be in one of several states (see Configuring DNP3 Binary Points).
- DNP3 Binary Output Point—a 1-, 2-, or 3-bit point that is used to control the status of an item of plant, where the plant may be controlled to be in either or one of several states (see Configuring DNP3 Binary Points).
- DNP3 Counter Point—a point that counts the number of pulses (see Configuring DNP3 Counter Points).
- DNP3 Frozen Counter Point—a point that monitors the number of counts registered by a Counter Point (see Configuring DNP3 Counter Points).
- DNP3 Pulse Action (NULL)—a one-action pulse (see Configuring DNP3 Pulse Actions).
- DNP3 Pulse Action (Trip-Close)—a two-action pulse, for which each action can be performed on the same, or on a separate physical point (see Configuring DNP3 Pulse Actions).
- DNP3 String Point—a point for which the value is a text string, rather than a numeric value (see Configuring DNP3 String Points).
To retrieve status information from a DNP3 device, consider using DNP3 Status Points, rather than the above DNP3 points (see Configuring DNP3 Status Points).
