springboot 通过博途获取plc点位的数据

springboot 通过博途获取plc点位的数据

1. maven依赖

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

   这个版本尽量是新版本，不然有的返回的值对应的类型不存在
2. 代码实现

public void sendHttpRequest() {
     System.out.println("==================================执行命令==================================" + 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( );
             // 根据ip查询对应的命令
             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("==================================结束命令==================================" + System.currentTimeMillis());
    }

因为需求，DBW是整型，DBD是浮点数，DBX是布尔值
DBW/D/X后面对应的是偏移量，
3. 测试方法

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 operateResultExOne = siemensS7Net.ReadBool("DB5.0.1", (short) 4);
  if (operateResultExOne.IsSuccess) {
      for (Boolean boo:operateResultExOne.Content) {
          System.out.println("------------"+boo);
      }
  } else {
      System.out.println("错误信息："+operateResultExOne.ErrorCode + "=====" + operateResultExOne.Message);
  }*/
}

（short）对应的值是获取几位，因为需求，没办法一起获取，所以我是单个获取的
