4.2 Switch input DI
4.2.1 Switch input DI collection
Switch input DI to measure level signal or edge pulse signal (rising edge, falling edge). Support dry node collection,
support DI counting function, the maximum count is 65535 (the count is automatically cleared when 65535 is exceeded).
The switch input DI supports three trigger modes: rising edge, falling edge, and level (the default level trigger
mode).
The clearing method supports automatic clearing and manual clearing (default automatic clearing).
4.2.2 Switch input DI filter parameters
When the switch inputs the DI to collect the signal, it needs to keep multiple sampling periods before confirming.
The filter parameter can be set from 1 to 16 (default 6 sampling periods). The DI filter parameters can be set through the
configuration software.
4.3 Switch output DO
4.3.1 Switch output DO description
Switch output DO, with level mode, pulse mode, follow mode (only follow DI). Using C-type relay output
(normally open + normally closed), the single-channel output supports a maximum load (contact capacity) of 30V/10A or
250V/10A.
Each DO output is designed with an output indicator (red LED indication) to indicate whether the output port is on
