WRITE_MODBUS_DATA

This is a structure information to define a Modbus TCP write configuration, used for transmitting data from the robot controller to an external Modbus slave device via Ethernet (TCP/IP).

BYTE#	Field Name	Data Type	Value	Remarks
0	_szSymbol	char[32]		Symbol name (32-byte identifier)
32	_szIpAddr	char[16]		Target device IP address (IPv4 string)
48	_iPort	unsigned short		TCP port number (e.g., 502)
52	_iSlaveID	int		Slave device ID (1-255)
56	_iRegType	unsigned char		Register type 0: Coil, 1: Discrete Input 2: Holding Register, 3: Input Register
58	_iRegIndex	unsigned short		Register address (index)
60	_iRegValue	unsigned short		Register value (0-65535)
