Detailed Description

Thic class represent Modbus exception and is derived form std::exception. It is just a wrapper around standard error codes and some custom codes.

Constructor & Destructor Documentation

ModbusException::ModbusException	(	const std::vector< uint8_t > &	inputData,
		bool	CRC = false )

explicitnoexcept

Constructs Exception from raw data.

Parameters

inputData	is vector of bytes that will be be interpreted
CRC	based on this param method performs CRC calculation and throws exception if it is invalid

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

const char * MB::ModbusException::what ( ) const

inlineoverridenoexcept

This function is less optimal, it is just to be compatible with std::excepetion You should preferably use toString()
