A question about souce code of ModbusDriver-v2

I have read the example of Ignition-ModuleSDK-7.2.8\example\ModbusDriver-v2.

I am wondering which code is sending the original data to modubus driver and which code is receiving original data from the modbus driver,.please give me some help,thank you

I’m not sure what you mean by “original data”… Can you elaborate?

I mean the data which send to modbus driver such as "Function Code+Starting Address+Quantity of Registers " and the data which is responded by the modbus driver.
