ref - the reference number of the register to read from.count - the number of words to be read.public ReadInputRegistersResponse getResponse()
ModbusRequestThe response must include the unit number, function code, as well as any transport-specific header information.
This method is used to create an empty response which must be populated by the caller. It is commonly used to un-marshal responses from Modbus slaves.
getResponse in class ModbusRequestpublic ModbusResponse createResponse(AbstractModbusListener listener)
ModbusRequestThe implementation should take care about assembling the reply to this ModbusRequest.
This method is used to create responses from the process image associated with the listener. It is commonly used to implement Modbus slave instances.
