산업용 통신 프로토콜

책 PLC 데이터 통신(구민사) 참고

 

PLC 수치체계

bit : 0 or 1(참 or 거짓)을 표현할 수 있는 기본 데이터 단위 (ex. P0~, M0~ 등이 해당)

byte : 1byte = 8bit = 2의 8승

word : 1word = 2byte = 16bit

double word : 1 double word = 2 word = 4byte = 32bit

 

P영역 : 기본적으로 I/O(Input/Output) 할당이 되는 메모리

 

모드버스 TCP IP 프로토콜 구조

FCode : BitMemory에 값을 읽을 건지(BitRead 0x01)

            BitMemory에 값을 읽을 건지(BitRead 0x05)

            WordMemory에 값을 읽을 건지(WordRead 0x03)

            WordMemory에 값을 읽을 건지(WordRead 0x06)

Data : 몇번 Address의 값, 몇 개를 읽을 건지 or 몇번 Address에 무슨 값을 쓸 건지

TID, PID는 디바이스에서 제공하는 메뉴얼을 참고하여 값을 바꾸면 된다.

Mqtt 메세지 받으면 생산량 리미트 D10000에 데이터 쓰기

(Mqtt value를 받아서 그 값을 write)

 

맨 위의 Form 부분에 MQTT 연결 코드 추가

(어젠 Form oad에 적었었는데 여기에 적어도 된다.)

Form1.cs

\Desktop\IOT\visual studio edukitTest\modbus_wordWrite\modbus_wordWrite

    public partial class Form1 : Form
    {
        static MqttClient mqttClient;
        public Form1()
        {
            InitializeComponent();
            // form 더블클릭하여 자동생성 했음
            //form load 될때 mqtt가 연결 시도를 할 수 있도록 여기 작성 
            mqttClient = new MqttClient("localhost", 1883, false, null, null, MqttSslProtocols.TLSv1_2); // 로컬호스트의 1883 포트에 연결
            mqttClient.ProtocolVersion = MqttProtocolVersion.Version_3_1_1;    // 기본값 3.1.1, 버전이 맞아야 연결된다.
            mqttClient.MqttMsgPublishReceived += MqttClient_MqttMsgPublishReceived;


            //mqttClient.ConnectionClosed += MqttClient_ConnectionClosed;

            byte code = mqttClient.Connect(Guid.NewGuid().ToString());                                      // clientID
            mqttClient.Subscribe(new string[] { "test" },
                new byte[] { MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE });
        }

 

subscribe 받아서 뭘 할지 명령 추가

        private void MqttClient_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e)
        {
            // mqtt 데이터 신호 받았을 때(subscribe) 무슨 처리를 할 지 작성하는 메소드
            string mes = Encoding.Default.GetString(e.Message);
            Console.WriteLine(mes);

            byte[] SendData = new byte[]
{
                0x00, 0x00,
                0x00, 0x00,
                0x00, 0x06,
                0x01,
                0x06,
                0x27, 0x10, // D10000
};
            byte[] Data_W = BitConverter.GetBytes(Convert.ToInt16(mes));
            byte[] Data = new byte[] { Data_W[1], Data_W[0] };
            SendData = Combine(SendData, Data);
            SendMessage(SendData);
        }

난 짤 때 SendData에 대체 뭘 넣어야하나 고민했는데 그냥 위처럼 넣어서 mes로만 해주면 되는 거였다...

 

근데 이렇게 하면 소켓서버쪽에 어제도 발생했던 에러가 발생한다.

invoke를 붙여서 해결

                this.Invoke(new Action(() =>
                {
                    TB_SendFrame.Text = BitConverter.ToString(SendData);
                }));

결과

MQTTX에서 퍼블리싱한 234 값이 D10000에 적히는 것을 확인할 수 있음

 

이더넷 전용 통신

서버 모드 변경

XG5000 - 내장~FEnet

변경해주고 쓰기(링크인에이블 체크 해제)해주면 된다.

 

TCP 포트번호

(modbus는 502를 썼다)

 

XGT 전용 프로토콜 구성

고정영역은 건드리지 않는다.

Form1.cs

변수개수 수정(3개 -> 5개)

            DataFrame = Combine(DataFrame, VariableBlock);

            return DataFrame;
        }

메모리 값 위치 지정(이건 잘못된 코드로 밑에서 수정하게 된다)

        private byte[] MakeVariableBlock()
        {
            byte[] VariableBlock = new byte[0];

            VariableBlock = MakeBlock("%DW10000", VariableBlock);

            return VariableBlock;
        }

읽어올 변수명 길이 수정(8글자)

        private byte[] MakeBlock(string VariableName, byte[] VariableBlock)
        {
            byte[] VariableLength = new byte[2] { 0x08, 0x00 }; // 변수명 길이 최대 총 8글자

            VariableBlock = Combine(VariableBlock, Variable);

        {
            short Datas = BitConverter.ToInt16(RData, 32);  // 앞의 데이터는 다 쓸모 없어서 스킵

여기까지 수정하고 나니

값이 5로 지정되어 있어 0이 뜨지 말아야 할 생산량 리미트까지 0이 떴다(뭔가 오류가 있음)

강사님이 보시고 수정한 변수명 길이는 8글자인데 기존 변수명은 5글자라서 오류가 난 것 같다고 알려주셨다.

그래서 위의 변수명 길이도 수정해줬다.

결과

위에 했던 내용들의 반복이라 크게 어려운 부분은 없었다.

 

 

근데 궁금한 게 생겼다.

WordRead에서도 그렇고 WordWrite에서도 처음 시작할 때만 타입?을 지정해주고 다음은 그냥 쓰는 것 같은데 그 이유가 궁금해서 앞에 또 붙여봤다.

오류 메세지엔 이미 지역 변수/함수가 정의되어 있다고 떴다.

아 위에 정의한 걸 밑에서 또 쓰는 거구나...하고 이해했다.

JS나 파이썬은 그래도 나름 몇번 봤다고 저게 헷갈리진 않았는데...C#에선 저렇게 생겼구나...

 

 

비전 인식

주사위 값

C#은 너무 복잡하기 때문에 파이썬으로 진행

소켓으로 보낼 데이터 값은 어디서 보는가?

=> WordWrite 수정해서 디버그하여 알아볼 수 있다.

        private byte[] MakeDataFrame()  // command에 해당
        {
            byte[] DataFrame = new byte[]

디버그

=> F9로 해당 구문에 중단점 생성 - F5로 실행 - 마우스 갖다 대고 왼쪽 화살표 클릭하여 자세한 데이터값 확인 가능

 

디버깅 단축키

F9 중단점

F5 중단점마다 실행

F10 다음 코드 실행

F11 프로시저 실행

멈춰 있는 상태에서 마우스 갖다 대면 값이 다 보임

 

결과

주사위 값이 변할때마다 읽어온다

 

이런 식으로 연동하면 좋다.

느낀 점

점점 코드에 익숙해지는 속도가 빨라지는 것 같아 뿌듯하다.

비전 인식 코드에서 익숙한 코드가 몇 줄 보여서 반가웠다.

배운걸 잘 하는데 그치지 않고 하나를 배워서 응용하는 능력이 좀더 좋아졌으면 좋겠다.

계속 코드를 보면서 익숙해져야지...
