IV. Product Function Introduction
4.1 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.
4.1.1. Input count
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.
4.1.2. Level output
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.
4.1.3. Pulse output
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).
4.1.4. Follow mode
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
