//tips： 外部使用这个service的read、write操作 要异常捕捉，然后在catch里面 用logger.info("记录下异常。"),这里的异常是不会被捕捉的只会向外抛。
//关于对String、String[]操作需要注意：
// ① 单体变量 length 都是1
// ② 数组变量 length 就是 你要read 或者write数组的长度
// ③ bitOffset 是针对Bool 来说的，其他变量bitOffset 都是0
// ④ strSize 这个字段只是给 String变量 和 String[]变量 用的, 这个字段是plc中设置的最大String长度
// ⑤ String类型 在write的时候禁止 write中文，因为plc中编码并没有采用UTF-8 而是采用ASCII
// （同理也是，当plc中有设置String类型或者StringArray那么告诉他们必须指定长度 通常他们也会指定长度的。）
