Using the Analog Scaling Dialog Box

The Analog Scaling dialog box allows you the analog scaling parameters of an input or set of inputs.

The dialog consists of three sections:

• Select Scaling option

• Scaling Details

• Buttons

Select Scaling Option

The Select Scaling option allows you to assign individual scaling parameters to a set of inputs or to default to the IED scaling options.

• IED Defaults: Selecting this option sets the scaling options for the points to the IED’s default values.

• Point Overrides: Selecting this option allows you to override the IED default scaling options for the selected points.

Scaling Details

The following scaling parameters are available to set:

• Absolute Change: The absolute deadband value

• Percentage Change: The percentage deadband value

• Multiplier: The scaling multiplier to apply.

• Offset Before Multiplier: The offset to apply to the value before any multiplier is applied. Negative values are subtracted.

• Offset After Multiplier: The offset to apply to the value after any multiplier is applied. Negative values are subtracted.

Each of the scaling parameters has two values:

• IED: The IED default value. This field is not editable.

• Point: The override value that will be used instead of the IED value. This field is only editable if the Point Overrides scaling option is enabled.

Buttons

• OK: Selecting OK closes the dialog and applies the scaling.

• Cancel: Selecting cancel closes the dialog and cancels the operation.

• Help: Selecting help invokes the online help.

IED Outputs

This display shows a protocol specific list of the output points on the IED. Context sensitive menu options allow creation, deletion and editing of output points.
