ModBus RequesMapping Sensors (T1, T2) to ADC Channels on KC868-A6

[ka.mobo]

Hello Admin

I am currently working with ModBus RS-485 the KC868 series board (specifically the KC868-A6) and would like to understand how analog sensors, such as T1, T2, or other analog inputs, are mapped to the ADC channels in the hardware configuration. (I am using the Firmware KCS_KC868_A6_V2.2.5)
Could you please provide:

1. Hardware documentation that specifies the connection of sensors (T1, T2, etc.) to the ADC channel register addresses.
   
2. Any relevant details or examples for configuring and reading sensor data using Modbus function code 03.
   
   

This information would greatly assist in correctly interpreting sensor data from the board.
