Detailed Description

This class represents Modbus response and allows user to manipulate and represent it in various ways

Constructor & Destructor Documentation

ModbusResponse() [1/2]

ModbusResponse::ModbusResponse ( std::vector< uint8_t > inputData, bool CRC = false )

explicit

Constructs Response from raw data.

Note

1) if CRC = true input data needs to contain 2 CRC bytes on back (used in RS)

2) This is private constructor, you need to use fromRaw or fromRawCRC

Parameters

inputData

- Is vector of bytes that will be be interpreted, whereas based on CRC parameter method performs CRC calculation and throws exception if it is invalid

Exceptions

ModbusException

ModbusResponse() [2/2]

ModbusResponse::ModbusResponse	(	uint8_t	slaveId = 0,
		utils::MBFunctionCode	functionCode = static_cast<utils::MBFunctionCode>(0),
		uint16_t	address = 0,
		uint16_t	registersNumber = 0,
		std::vector< ModbusCell >	values = {} )

Simple constructor, that allows to create "dummy" ModbusResponse object. May be useful in some cases.
