The Geo SCADA Expert DNP3 SCADAPack E driver provides a DNP3 SCADAPack Counter Point that enables you to configure physical counters in the SCADAPack E outstation. Physical counters are used to count pulses on the physical binary inputs of the outstation.
By default, physical counters are positive edge triggered (that is, they count off-to-on transitions). If you want to count on-to-off transitions, create a DNP3 SCADAPack Binary Input Point for the physical binary input and set its Invert Point State property (see Configure any Physical Binary Input Point Properties). You do not need to create a DNP3 SCADAPack Binary Input Point if you only need to use the default configuration of the physical binary input.
You configure the properties of each counter point using the DNP3 SCADAPack Counter Point Form. The Form has several tabs. This section covers configuration of properties on the Counter Point and Mapping tabs of the Form.
Use the Counter Point tab to:
- Configure General Properties
- Configure Alarm Limits
- Optionally Associate one or More Profiles with the Point
- Configure Initialization Properties (see Configure the Initialization Properties of a DNP3 Counter Point in the Geo SCADA Expert Guide to the DNP3 Driver)
- Configure Override Properties (see Configure Override Properties in the Geo SCADA Expert Guide to the DNP3 Driver)
- Configure Significant Change Properties
- Configure the No Change Properties (see Detect Whether a Point Value has Stopped Changing in the Geo SCADA Expert Guide to Core Point Configuration)
- Configure Trend Properties (see Define a Counter-Type Point’s Trend Settings in the Geo SCADA Expert Guide to Core Point Configuration)
- Configure Formatting Properties (see Define the Appearance of a Counter-Type Point’s Values in the Geo SCADA Expert Guide to Core Point Configuration)
- Configure Logged Data Properties (see Configure Logged Data Properties in the Geo SCADA Expert Guide to the DNP3 Driver)
- Specify the Point Data Class that Applies when Communicating with another DNP3 Master.
Use the Mapping tab to:
The properties on other tabs are common to points on many advanced drivers—for information, see Tabs on Point Forms in the Geo SCADA Expert Guide to Advanced Drivers.
If the outstations on your system are to sample counter point data for data trends, you need to configure the required Trend item(s) in the database and associate those items with the relevant counter points (see Configuring DNP3 SCADAPack E Trend Sampler Functionality).
