1、引入依赖

<dependency>
                    <groupId>com.github.dathlin</groupId>
                    <artifactId>HslCommunication</artifactId>
                    <version>3.1.1</version>
                </dependency>

2、使用SiemensS7Net获取opc数据

    /**
     * 测试90
     */
    public static void test90() {
        SiemensS7Net siemensTcpNet = new SiemensS7Net(SiemensPLCS.S1500, "172.18.1.90");
        // 有符号的16位 地址：DB5.DBW528   字段名称：new_silo2_high_voltage_in
        //byte[] getBytes = siemensTcpNet.Read(DaveArea.DB, 5, 2, 528);
        //OperateResultExOne<byte[]> read = siemensTcpNet.Read("DB572.48", (short) 4);
        OperateResultExOne<byte[]> read = siemensTcpNet.Read("DB5.DBW524", (short) 2);
        //String str = getBinaryStrFromByte(getBytes[0]);
        //System.out.println("getDoubleData:"+str);
        //105代表读取的长度
        //OperateResultExOne<byte[]> read = siemensTcpNet.Read("I32", (short) 1);
        OperateResultExOne<boolean[]> read1 = siemensTcpNet.ReadBool("I188", (short) 1);
        OperateResultExOne<Boolean> i188 = siemensTcpNet.ReadBool("I188.4");
        OperateResultExOne<Boolean> i1881 = siemensTcpNet.ReadBool("I188.5");
        OperateResultExOne<Boolean> i1882 = siemensTcpNet.ReadBool("I188.6");

        if (read.IsSuccess) {
            // I74: 10100101
            // 2:1 4:0 0:1 3:0
            // I188: 11000100
            // 4:0 5:0 3:0 2:1 7:1 6:1
            byte[] content = read.Content;
            String str = getBinaryStrFromByte(content[0]);
            System.out.println("getDoubleData:"+str);
            //2是下标
            //short no = siemensTcpNet.getByteTransform().TransInt16(content, 2);
            //System.out.println(no);
        }

    }
