Modbus Driver¶

BrowseName: ModbusDriver
SuperType: Communication driver (CommunicationDriver)

Driver to communicate with the PLC via the Modbus protocol.

Properties¶

Name	BrowseName	DataType	Description
Protocol	Protocol	ModbusProtocol	Modbus TCP: TCP Socket access mode. Modbus RTU: serial port access mode.
Serial port	SerialPort	String	(in RTU mode only) Number of the COM serial port to use for the communication.
Baudrate	Baudrate	UInt32	(in RTU mode only) Serial communication speed (Baud Rate). The communication speed value should be set to match that of the device with which you intend to communicate.
Data size	DataSize	Byte	(in RTU mode only) Number of bits of a single character required by the communication protocol concerned.
Parity	Parity	Parity	(in RTU mode only) Parity bit for handling transmission errors. Even: if the 1-bits in a byte are odd, add a 1-bit until the 1-bits are even. Odd: if the 1-bits in the byte are even, add a 1-bit to make them odd.
Stop bits	StopBits	StopBits	(in RTU mode only) Number of stop bits required by the communication protocol concerned.
Flow control	FlowControl	FlowControl	(in RTU mode only) Type of data flow control for the type of communication used. None: no flow control - the control is not required by the protocol; Hardware: the flow control is managed by serial line electrical signals (e.g. RTS, CTS, etc.); Software: the flow control of data is XON/XOFF.
