Create and Configure IEC 61850 Digital Points and Contols

The Geo SCADA Expert IEC 61850 driver supports IEC 61850 Digital Points and Digital Controls. Use an IEC 61850 Analog Point to map a Data Attribute with a functional constraint other than CO to a Digital Point in the Geo SCADA Expert database. IEC 61850 Analog Control to map a Data Attribute with a functional constraint of CO to a Digital Control in the Geo SCADA Expert database. An Analog or Digital Point cannot be mapped to a Data Attribute with a functional constraint of CO.

You can create Digital Points and Digital Controls in the Geo SCADA Expert database, as defined in the SCL file. For information about how to create points, see Points Used On IEC 61850 Device.

Configure the properties of each Digital Point and Digital Control using the fields on the IEC 61850 Digital Point and IEC 61850 Digital Control Forms.

This section covers configuration of the digital-specific properties on the Digital Point tab, the Control tab, the Write tab, and the Control Checks tab of the Form. Most of these properties are configured automatically when the points are created. You only need to change the settings if they are to differ from the defaults, or comprise property values that need populating.

The configuration Form contains many fields, organized into tabs. Most of these tabs contain properties that are common to points on many drivers (see Tabs on Point Forms in the Geo SCADA Expert Guide to Advanced Drivers).

Use the Digital Point tab to:

• Configure General Properties on the Digital Point Tab.
• Define the format of displayed value (see Define the Format of a Digital Point’s Values).
• Configure the states for the point (see Configure Digital Point States).
• Define whether a Digital Point can be Overridden).
• Configure Polling.

For information on the Control properties,Configure the Control Properties of an IEC 61850 Digital Control.

For information on the Write properties, Configure the Write Properties of an IEC 61850 Digital Point

You can optionally use the Control Checks tab to configure the Control Checks settings (see Configuring Control Checks Settings in the Geo SCADA Expert Guide to Core Point Configuration).

Properties on other tabs are common to many points, see Tabs on Point Forms in the Geo SCADA Expert Guide to Advanced Drivers.
