Note: *Only when the control method is set to "Closed-loop control", the parameter "-
Select energy meter" is settable.
step 4 (Optional) If AI configuration is selected, click "AI Configuration“ to set voltage and
current sampling parameters for the selected AI port.
step 5 After finishing parameter setting, click "Save" to save the operation.

10.2.1.5 Digital Input
When using the digital signal at the DI port of the Logger4000 as the dispatching input,
set the active control mode to "Digital input".
step 1 Click "Power control" -> "Active power" to enter the active power interface.
step 2 Set the active control mode to "Digital input".
step 3 Set DI control parameters. For specific parameter description, refer to the following
table.

Control method
Open loop control: Active instruction controlled by DI is
sent to the power output port of the inverter, thereby
achieving active power control.
Closed-loop control:
• In case no Smart Energy Meter is selected, active
instruction controlled by DI is used as target value,
and active power compensation ratio is calculated
and sent to the power output port of the inverter.
Generally, this strategy is used for fast and accurate
active power regulation.
• In case a Smart Energy Meter is selected, active
instruction controlled by DI is used as target value,
active power of the meter needs to be collected and
used as input parameter, and active power
compensation ratio is calculated and sent to the
power output port of the inverter. Generally, this
strategy is used for anti-backflow or avoiding zero
power feed-in.
