Descriptions
Value Type
Specify the date type the Publisher application uses
when reporting the analog input.
RTDB Point
Specify the RTDB point whose value is reported for
the analog input. A custom window allows you to
associate the analog input to any analog input or
counter available in the D20E.

To set up the Analog Input for the calculation function (that is, for the raw standard (16 bit
Integer) in the legacy D.20 Input/Outputs):
1.
Navigate to Settings > Providers > IO Provider > IED > Analog Input > Calculation.
2.
Set MULTIPLIER to a value pf 2.
3.
Navigate to Settings > Providers > IO Provider > IED > Analog Input > Protocol.
4.
Set SCALE to Calculation.
You must set the scaling to Calculation in order for these settings to work. For details see
the DAPserver Studio online help.
When configuring a D20E for Analog Input from a Substation Controller device (for
example: D20ME, D20MEII, or D20MX) or a Substation Gateway device (for example: D400
or DMC490), a signed 16 bit range (-32,768 to +32,767) is required from the D20E Publisher
in a Signed Integer format.
Since the Raw value is a signed 15 bit value, it must be doubled.
