trigger).
The clearing method supports automatic clearing and manual clearing (default automatic clearing).

4.2.2 Input filtering

When the switch input DI collects the signal, it needs to keep several sampling cycles before confirming. Filter
parameters can be set in the range of 1 to 16 (default 6 sampling periods, 6*1kHz).
It can be configured with the host computer through instructions.

4.2.3 Input count

It supports counting DI input, and users can configure it as rising edge acquisition, falling edge acquisition, and
level acquisition according to their own needs. The clearing method can also be changed as required.
Trigger method:
Rising edge: When the rising edge is collected (it does not count when it is turned on, it counts when it is turned
off), and it counts once.
Falling edge: The falling edge is collected (counts when it is turned on, not counted when released), and counts
once.
Level: Two edges are collected and counted once respectively.
Clearing method:
Automatic: The device will automatically clear each time the DI count value register (0x09DF~0x09E6) is read.
Manual: In manual mode, it is necessary to write 1 to the clearing signal register (0x0AA7~0x0AAE). Each holding
register controls one clearing signal.

4.3 Active upload

When the device is connected in client mode, and the automatic upload function is enabled. When the state of
the input of the device changes or the device is connected to the server for the first time, the input state of the
device will be sent to the server in Modbus TCP format.
[Note] The device can only be valid if it is in the client mode configuration. If the register value is non-zero,
it means that the DI is enabled for active uploading.

4.4 AI input

4.4.1 Analog range

The analog input AI measures the current signal, the acquisition range is 0~20mA or 4~20mA, the accuracy is
1‰, and the resolution is 12 bits.
Single-ended input is adopted, the sampling frequency is 10Hz, and the input impedance is 100Ω.
Set the sampling range of all AI channels, valid values are 1 and 0 (default 0).
