MODBUS_MULTI_REGISTER

This is a structure information to store multiple Modbus register values within a single device. It includes symbol name, register count, register values, starting register address, and slave ID.

BYTE#	Field Name	Data Type	Value	Remarks
0	_szSymbol	char[MAX_SYMBOL_SIZE]		Modbus I/O symbolic name
32	_iRegCount	unsigned char		Number of registers
33	_iRegValue	unsigned short[MAX_MODBUS_REGISTER_PER_DEVICE]		Register values
133	_iRegIndex	unsigned short		Starting register address
135	_iSlaveID	unsigned int		Slave device ID
