I'm very sorry for the inconvenience caused to you. The following is the complete register address table content:

Register Address Table

1. Simplified Register Address Table

2. Loop control register address

3. Scene setting register address

I apologize to you, there was indeed an error. Let me reorganize and provide the remaining part of the scene settings register address in its entirety.

Scene Setting Register Address (Continued)

Continuing with the scenario above, set the register address table:

These addresses are used to configure and call different scenes, and each scene can set brightness values for 8 circuits (channels). The brightness value range of each circuit is 0-100%, which is set by writing data to the corresponding register.

Of course, I will continue to provide the remaining register address table information in the document:

4. Gradient time register address

5. Power on brightness register address

6. Address of the minimum brightness value register

7. Address of the maximum brightness value register

8. Time and Date Setting Register Address

9. Week Timer Setting Register Address

10. Setting register address for sunrise and sunset

11. Auxiliary Register Address

These auxiliary registers provide additional flexibility, allowing users to store and manipulate more custom data. For example, gradient time registers and brightness registers can be used to control the gradient effect and brightness level of lights, while reserved registers provide space for future functional extensions or specific applications. The

These addresses are used to set and call different scenes, and each scene can be configured with brightness values for 8 circuits (channels). By writing data to the corresponding registers, precise control of light brightness can be achieved.

Based on the screenshot you provided, I will continue to supplement and improve the detailed information of the scene setting register address:

These register addresses allow users to configure different brightness levels for each circuit, creating multiple lighting scenarios. Through the Modbus protocol, users can write data to these registers to set or modify scene configurations.

Use scenario configuration instruction register (10H function code)

For example, to configure the state of scenario 1 to enable all circuits 1-8, the following command can be used:

• Instructions:01100040000810006400640064 006400640064 006400640064 006400640064 99C4
• Feedback:011000400008C01B

This instruction uses a 10H function code to write multiple register values at once. In this example, it sets the brightness value of all circuits (1-8) in scene 1 to 100% (64H).
