automatically take the closest value and write it in. If the filter parameter is written as 0, the device will take 1 as

the filter parameter, and Modbus does not return error commands.

4.3 DO output

Relay output mode: output different mode output according to the mode set by the user, and the level output is

turned on by default.

Support counting DI input, users can configure rising edge acquisition, falling edge acquisition, and level

acquisition according to their own needs. You can also change the clearing method according to your needs.

Trigger method:

Rising edge: When the rising edge is collected (it is not counted when it is turned on, it is counted when it is

turned off), it will be counted once.

Falling edge: When the falling edge is collected (counting when it is turned on, and not counting when it is

released), count 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 clear signal register (0x0AA7~0x0AAE), and each

holding register controls one clear signal.

Output according to the level set by the user, the switch characteristic of the level mode is similar to the

function of a self-locking switch.

After the switch output DO is turned on, the switch output DO is automatically turned off after maintaining the

set pulse width time (in ms). The pulse width setting range is 50~65535ms (50ms by default).

According to the follow source configured by the user (when the device has AI acquisition or DI detection

function, both DI or AI can be used as the follow source, otherwise this function is useless) to change the relay state,

and multiple outputs can follow the same follow source output. To put it simply, DI detects the input, and

automatically outputs a relay that uses it as a follow source (for example: DI is 1, DO is closed). When the follow

mode is turned on, the follow source should be configured at the same time, otherwise it will follow the first input

by default.
