我用两组CPU-313DP建立PROFIBUS-DP网络，因为我的通讯字节没有超过4个，所以我用简单的定义主从站输入输出口方式，但在组完编译后，出现两个警告，内容如下：
outputs for station"cpu1":
warning:attention: in station"cpu1"there are additional nodes that also have to be reloaded.
outputs for station"cpu2":
warning: attention: in station"cpu2""there are addtionnal nodes that also have to be reloaded.
result:0 error(S),2 warning(s)
