CHAPTER 3: CONFIGURING THE D20E FIRMWARE
D20E ETHERNET I/O MODULE INSTRUCTION MANUAL
Setting
Descriptions
Point
Specify a descriptive label for the digital input.
Description
This setting is used in the HMI Application Point
Status Viewer and Event Recorder.
Value Type
Specify the data type the Provider application uses
when storing the digital input in the database.
For detailed information on the Value Types and the
specific Provider and Publisher settings, see
15: Provider IO and Publisher Protocol - Value
Type:
on page 68.
Initial Value
Specify the initial analog value that appears in the
database during initialization.
A value may be chosen which makes it convenient to
identify the initialization value. For example, -50 for a
132 kV line would indicate this voltage has not been
updated.
Historical settings
Note: The D20E does not currently support the Historical data settings.
Calculation settings
Note: In order to use the calculation tab for D20Es; under Provider IED Analog Input Protocol, the
scale method must be set to calculation. Otherwise no calculation is applied on the Analog Input.
Reference
Specify a text string that combines the bay name,
Name
group name, and provider name from the General
tab.
Min Value
The function of the Min Value setting is determined
by the selection made under Transform Method:
• Scale - Specify the minimum value permitted for
this analog input. The DAP updates the database
with this value whenever the device reports that
this analog input value is less than this minimum.
The minimum value must be set less than or equal
to the associated Max Value setting. If no value is
specified, the minimum value checking for this
analog input is disabled,
For detailed information on the IO Scale and the
specific Provider settings, see
16: Provider- IO Scale:
• Percentage - Specify the minimum range for this
analog input. The DAP will use this value as its
minimum range (0%) during its calculation.
Percentage Example:
• Min Value = 0
• Max Value = 1000
• If percentage is at 50%, the Explore window
shows 500
