433M Wireless Controller - Slave

The 433M wireless controller uses the 433M frequency and a one-to-many communication method, that is, one master controls multiple slaves, so as to control and manage the equipment in a factory.

I. Wireless Controller Communication Method
The 433M wireless controller (hereinafter referred to as the wireless switch) adopts a one-to-many communication method, that is, one master communicates with multiple slaves through polling. This control system supports a maximum of 20 slaves. The PC-side host computer software can configure and acquire the status of the slaves.

433M Wireless Controller - Main Unit

The 433M wireless controller uses the 433M frequency and a one-to-many communication method, that is, one master controls multiple slaves, so as to control and manage the equipment in a factory.

I. Overview
1.1 Wireless Controller Communication Method
The 433M wireless controller (hereinafter referred to as the wireless switch) adopts a one-to-many communication method, that is, one master communicates with multiple slaves through polling. This control system supports a maximum of 20 slaves. The host computer software on the PC can configure and acquire the status of the slaves.
The PC sends commands to the master via RS485, and the master then sends the commands to the corresponding slaves via the 433M wireless communication module. Upon receiving the command, the slave sends its status to the master via the 433M module, and the master then sends the slave status to the host computer via RS485.

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
