D20E ETHERNET I/O MODULE INSTRUCTION MANUAL
For communication with a GE Grid Solutions:
•
A D2x substation controller product supports Short Floating AI, which may benefit
from the use of engineering units.
•
The D400 substation gateway (and other newer products) support floating AI.
To configure the D20E Ethernet I/O Module for 16-bit signed integer AI format:
1.
From the DAPserver Studio, go to IO Provider > IED > Analog Input > Protocol.
Result: The Protocol drop-down menu appears.
2.
Select Raw.
3.
Go to DNP3 Publisher > View > Analog Input > General > Value.
Result: The Value drop-down menu appears.
4.
Select Signed Integer.
5.
Go to DNP3 Publisher > View > Analog Input > Protocol > Divisor column.
6.
Type 0.5 in the Divisor column.
7.
Click Save.

All control commands can only be executed when the control target point is online.
Only trip/close, raise/lower, and pulse operations are currently supported. Multiple point
latching on digital outputs is not currently supported.
A Control Output point can be configured into the counter types listed in Table 17.
Table 17: Control type descriptions
Control type
Description
Trip/Close Control
A type of control output that provides a trip open or close using one of two
master relays and a select relay. During execution of the control
command, the selected relay is set:
• On after the master relay is set and
• Off before the master relay is off.
Dual Point Counter
Refer to section:
Form C Control
Uses 2 complementary contact outputs:
• One normally open, and
• One normally closed.
DPST Control
Double Pole, Single Throw with positive and negative control supply to
drive an external interposer relay.
Raise/Lower Control
A type of control output that raises or lowers output voltage using a single
select relay for each raise/lower control output.
Dual point counter
