SSCP Protocol implemented in Go

SSCP Driver for Go

SSCP protocol implmentation for Go.

This implementation heavily depends on the specification presented in the doc folder of the project root. SSCP protocol is simply a protocol for communicating with PLCs. Now, it is possible to read/write variables with go language.

Example Usage

	conn, err := sscp.NewPLCConnecetion(os.Args[1], 1, true)

	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}


	res, err := c.Login("admin", "rw", "", 10240)

	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}

	vars := []*sscp.Variable{
		&sscp.Variable{
			Uid:    9980,
			Offset: 0,
			Length: 4,
			Value:  []byte{},
		},
		&sscp.Variable{
			Uid:    9982,
			Offset: 0,
			Length: 4,
			Value:  []byte{},
		},
	}

	err = c.ReadVariablesDirectly(vars)

	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}

	for _, v := range vars {
		var value float32
		binary.Read(bytes.NewReader(v.Value), binary.BigEndian, &value)
		fmt.Printf("%+v %+v\n", v, value)
	}
