5.4 Data Exchange with Modbus

When fieldbus is configured as "Modbus TCP", user can exchange data, inquire the status of gateway and

manage according to the corresponding address of gateway in the internal input and output buffer; Also you can

do some trigger operation and transmission of universal frame.
