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.DBX8.5SiemensS7Net siemensS7Net = new SiemensS7Net(SiemensPLCS.S1200, "192.168.1.105");siemensS7Net.SetPersistentConnection( );//DBDOperateResultExOne<float[]> read = siemensS7Net.ReadFloat( "DB3.DBD10", (short) 4);if (read.IsSuccess) {for (float f: read.Content) {System.out.println("dbd:" + f);}}//DBWShort 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("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
