modbus 0.11.0
Modbus protocol
To use this package, run the following command in your project's root directory:
Manual usage
Put the following dependency into your project's dependences section:
Modbus protocol
Library provides modbus wrapper over RTU and TCP connections.
By default using serialport
package.
Simple usage:
auto mbus = new ModbusRTUMaster("/dev/ttyUSB0", 19200);
mbus.readTimeout = 2.seconds;
writeln(mbus.readInputRegisters(1, 17, 1));
Implemented functions:
- 01 (0x01)
readCoils
- 02 (0x02)
readDiscreteInputs
- 03 (0x03)
readHoldingRegisters
(returnsconst(ushort)[]
in native endian) - 04 (0x04)
readInputRegisters
(return in native endian too) - 05 (0x05)
writeSingleCoil
- 06 (0x06)
writeSingleRegister
- 16 (0x10)
writeMultipleRegisters
If you need other function you can use it directly:
auto res = mbus.request(dev, fnc, expectedDataLength, args);
where args
is compile time variadic arguments, they convert
to big endian by element for sending inside lib. res
returns
in big endian and you must convert to little endian by yourself.
And if you can test new function welcome to pull requests =)
For tcp connection using std.socket.TcpSocket
.
auto addr = "device_IP";
ushort port = 502; // or 503
auto mbs = new ModbusTCPMaster(new InternetAddress(addr, port));
writeln(mbs.readInputRegisters(1, 17, 1));
ModbusRTUMaster
and ModbusTCPMaster
close serial port and
socket in destructors.
You can configure library with custom serialport realization.
For this past subConfiguration "modbus" "custom"
to your dub.sdl
or "subConfigurations": { "modbus": "custom" }
to your dub.json
.
In this case you can't use ModbusRTUMaster
.
ModbusMaster
don't manage your serial port or tcp connection.
They uses through simple interfaces with read
and write
methods and
you must close opened connections by yourself.
Example:
import myserialport;
import modbus;
auto com = new MySerialPort();
auto mbus = new ModbusMaster(new RTU(new class Connection{
override:
void write(const(void)[] msg) { com.write(msg); }
void[] read(void[] buffer) { return com.read(buffer); }
}));
auto registers = mbus.readInputRegisters(device, address, count);
