這篇文章主要介紹了springboot?通過博途獲取plc點位的數(shù)據(jù)的代碼實現(xiàn),本文通過實例代碼給大家介紹的非常詳細,對大家的學習或工作具有一定的參考借鑒價值,需要的朋友可以參考下

springboot 通過博途獲取plc點位的數(shù)據(jù)

1.maven依賴

<dependency>
    <groupId>com.github.dathlin</groupId>
    <artifactId>HslCommunication</artifactId>
    <version>3.6.0</version>
</dependency>

這個版本盡量是新版本，不然有的返回的值對應的類型不存在

2.代碼實現(xiàn)

public void sendHttpRequest() {
     System.out.println("==================================執(zhí)行命令==================================" + System.currentTimeMillis());
     List<SysPlcIpEntity> ipList = plcIpDao.getIpList();
     if (ipList != null && ipList.size() > 0) {
         for (SysPlcIpEntity plcIp:ipList) {
             SiemensS7Net siemensS7Net = new SiemensS7Net(SiemensPLCS.S1200, plcIp.getIpAddress());
             siemensS7Net.SetPersistentConnection( );
             // 根據(jù)ip查詢對應的命令
             List<SysPlcMlEntity> plcMlList = plcMlDao.getListByIpId(plcIp.getId());
             if (plcMlList != null && plcMlList.size() > 0) {
                 for (int i = 0; i < plcMlList.size(); i++) {
                     if (plcMlList.get(i).getMlContent().contains("DBW")) {
                         OperateResultExOne<Short> dbwVal = siemensS7Net.ReadInt16(plcMlList.get(i).getMlContent());
                         if (dbwVal.IsSuccess){
                             plcMlList.get(i).setMlValue(String.valueOf(dbwVal.Content));
                         }
                     } else if (plcMlList.get(i).getMlContent().contains("DBD")){
                         OperateResultExOne<Float> dbdVal = siemensS7Net.ReadFloat(plcMlList.get(i).getMlContent());
                         if (dbdVal.IsSuccess) {
                             plcMlList.get(i).setMlValue(String.valueOf(dbdVal.Content));
                         }
                     } else if (plcMlList.get(i).getMlContent().contains("DBX")) {
                         OperateResultExOne<Boolean> dbxVal = siemensS7Net.ReadBool(plcMlList.get(i).getMlContent());
                         if (dbxVal.IsSuccess) {
                             plcMlList.get(i).setMlValue(String.valueOf(dbxVal.Content));
                         }
                     }
                 }
                 plcMlDao.batchUpdateMlList(plcMlList);
             }
         }
     }
     System.out.println("==================================結束命令==================================" + System.currentTimeMillis());
    }

因為需求，DBW是整型，DBD是浮點數(shù)，DBX是布爾值DBW/D/X后面對應的是偏移量，

3. 測試方法

public static void main(String[] args) {
  // DB5.DBX8.5
  SiemensS7Net siemensS7Net = new SiemensS7Net(SiemensPLCS.S1200, "192.168.1.105");
  siemensS7Net.SetPersistentConnection( );
  //DBD
  OperateResultExOne<float[]> read = siemensS7Net.ReadFloat( "DB3.DBD10", (short) 4);
  if (read.IsSuccess) {
      for (float f: read.Content) {
          System.out.println("dbd:" + f);
      }
  }
  //DBW
  Short content = siemensS7Net.ReadInt16("DB3.DBW0").Content;
  System.out.println("content" + content);
  OperateResultExOne<Short> long_array = siemensS7Net.ReadInt16("DB3.DBW0");
  if (long_array.IsSuccess){
      System.out.println("dbw:" + long_array.Content);
  }
  // DBX
 /* OperateResultExOne<boolean[]> operateResultExOne = siemensS7Net.ReadBool("DB5.0.1", (short) 4);
  if (operateResultExOne.IsSuccess) {
      for (Boolean boo:operateResultExOne.Content) {
          System.out.println("------------"+boo);
      }
  } else {
      System.out.println("錯誤信息："+operateResultExOne.ErrorCode + "=====" + operateResultExOne.Message);
  }*/
}

（short）對應的值是獲取幾位，因為需求，沒辦法一起獲取，所以我是單個獲取的
