Mode Description:
 Input
Mode: There are two input modes: normal contact and short contact. In normal contact mode, the input is ON when closed and OFF when open. In short contact mode, the state reverses once when the input is closed.
 Control Mode:
There are two control modes: remote and local. In remote mode, inputs and outputs are independent; the user can control the opening and closing of the output via commands
. In local mode, the controller's first 5 input points (IN0~IN4) and 5 output points (OUT0~OUT4) are interconnected; commands cannot control the outputs in this mode. In
remote mode ,




the status is read via commands
