This section provides information about DNP3 ‘Generic’ counter points (see DNP3 Master Configuration). If your system is running a DNP3 Extension Driver, other types of DNP3 counter point might be available. For information about non-generic DNP3 counter points, see the relevant DNP3 extension driver guide.
A DNP3 Counter point is typically used to count pulses on a physical binary input, or used to accumulate internally calculated values.
A DNP3 Frozen Counter point provides a mechanism for taking a ‘snap-shot’ of the current value of a DNP3 Counter—the Frozen Counter continues to hold the same value, while the Counter continues to count.
Configure the properties of a Counter point using the fields on the DNP3 Counter Point Form.
Configure the properties of a Frozen Counter point using the fields on the DNP3 Frozen Counter Point Form.
This section covers configuration of properties that are on the Counter Point tab of the Counter Point Form, and the Frozen Counter tab of the Frozen Counter Point Form. The fields on the other tabs are common to many points—for information, see Tabs on Point Forms in the Geo SCADA Expert Guide to Advanced Drivers.
For DNP3 Counter Points, use the fields on the Counter Point tab to:
- Configure General Properties of a DNP3 Counter Point
- Configure the Multiplier Value
- Configure Alarm Limits
- Configure the Initialization Properties of a DNP3 Counter Point
- Configure Override Properties
- Configure the No Change Properties (see Detect whether a Counter-Type Point 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.
For DNP3 Frozen Counter Points, use the fields on the Frozen Counter tab to:
