The DI parameters include
M1.DI1, M1.DI2, M1.DI3,
M1.DI4, and
Percentage(%).

Before connecting the SmartModule to the SmartLogger, if DI reactive scheduling has been
configured for the DI port and the scheduling signal needs to be connected to the SmartModule,
delete the DI configuration and reconfigure it.
 In the scenario where the SmartLogger and SmartModule are combined, if the SmartModule is
removed and the scheduling signal needs to be connected to the SmartLogger, delete the DI
configuration and reconfigure it.

Description
 Supports 16 levels of percentages.
"√" indicates a low level. When the four DI ports of the

SmartModule are connected, the ports are low-level ports.
When not connected, the ports are high-level ports.
 The percentage levels of M1.DI1 to M1.DI4 should differ
from each other.Otherwise, an exception will occur during
command parsing.
If the actual input DI signal is inconsistent with that
configured on the WebUI, the SmartLogger controls the
solar inverters to work at full load and generates the
Abnormal Reactive Schedule alarm.
Description
If the PV array is required to generate constant reactive power
at a specified time, set this parameter to Reactive power fix
control.
If the solar inverter is required to run with specified
maximum power in certain periods of a day, add setting
records based on site requirements.
When multiple time points are set, the solar inverter will run
with the maximum power specified for the time point that is
earlier than and the closest to the current system time. For
example, if you add 00:00:00 and 12:00:00 on the WebUI and
the current system current is 14:30:00, the solar inverter will
run with the maximum power specified for 12:00:00.
Description
If the PV plant is required to generate a constant power factor
at the grid-tied point and the solar inverter is required to
adjust the real-time reactive power based on the preset power
factor, set this parameter to Power factor fix control.
If the solar inverter is required to run with a specified power
