To set the module address for the SDM-8I8O module, you will need to use the switches on the module itself. Here is a step-by-step guide based on the information provided in the user manual:
1. **Locate the Switches:** The module has seven switches labeled SW1 to SW7 that are used to set the module address.
2. **Switch Positions:** Each switch corresponds to a specific value that contributes to the final module address. When a switch is in the ON position, its value is added to the total address.
3. **Calculate the Address:** Add up the values of the switches that are in the ON position to determine the module address. The address range is from 0 to 127.
4. ** ឧample:** If switches 1, 3, and 5 are ON, the calculation would be: Address = 1 (SW1) + 4 (SW3) + 16 (SW5) = 21.
5. **Setting Addresses Above 127:** Addresses from 128 to 255 can be set via RS485 or USB communication.
By following these steps and setting the switches accordingly, you can configure the module address for the aspar SDM-8I8O module to ensure proper communication and functionality within your system.
