Subject: Modbus write/read data error help.

Hi Modbus expert,

 

I am working on a Modbus RTU Temp & humidity sensor. Here is the driver configuration and error message after running the IOC. It seems the write/read length has error.

I am new to Modbus and don’t know how to make the correction. The last picture is the device protocol.
