operation. Parts of response data in the device will be stored to the buffer which is specified by this command

number.

6.4 Data Exchange with Modbus TCP

When fieldbus is configured as "Modbus TCP", user can exchange data, inquire about 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.
