Configure the Initialization Properties of a DNP3 Counter Point

Use these fields within the Initialize section of the Counter Point tab to define the initialization properties for a counter point:

• Enabled—Use this check box to specify whether operators can initialize the counter.
• Select the check box to allow operators to reset the counter value using the Initialize pick action. The initialize value is specified in the window that is displayed when the pick action is selected.
• If you allow initialization, you need to specify the DNP3 function and object that the outstation is to use to initialize the counter. To configure these properties, use the Reset Method field on the Outstation Form (see Configure the Counter Reset Method).
• Clear the Enabled check box to disable manual initialization. Operators will be unable to use the Initialize pick action for this counter point.
• Confirm—Use this combo box to specify whether confirmation is required from the user when initializing the counter (see Requesting Confirmation of Action Requests in the Geo SCADA Expert Guide to Core Configuration).
• Update Point on Successful Action—Use to define when Geo SCADA Expert updates the point’s value in the database following a Reset action. This setting only applies when the outstation’s counter Reset Method is set to a ‘Write’ option (see Configure the Counter Reset Method).
• If you select the Update Point on Successful Action check box, Geo SCADA Expert will update the value of the point in the Geo SCADA Expert database as soon as the outstation responds successfully to a Reset action.
• When a user selects the Reset action for the point, Geo SCADA Expert sends the Reset value to the outstation. The outstation then uses the Reset value and responds to Geo SCADA Expert to indicate whether the Reset action was successful. When Geo SCADA Expert receives a reset successful notification, it updates the point’s value in the Geo SCADA Expert database. This process normally happens very quickly.
• If you clear the Update Point on Successful Action check box, Geo SCADA Expert will only update the point’s value during a subsequent poll of the outstation. So, when the Reset value is sent to the outstation, Geo SCADA Expert does not update the database after the outstation’s response - it leaves the existing value of the point in place. Geo SCADA Expert only updates the point’s value in the database following the next poll of the outstation.
• You need to make the most appropriate selection for your requirements. Selecting the Update Point on Successful Action check box will mean that the point’s value is updated in the database when the Reset completes. But it also means that it will be updated with the user-defined value that was sent to the outstation. This may differ slightly to the value in the outstation as the outstation may re-interpret the value. For example, some hardware devices may be unable to represent the value and so will alter it. As a result, the value in the outstation may be slightly different to the value that was sent.
