我目前正在做两台PLC的通讯，两台PLC的配置均为315-2DP，想让其中一台作为主站，一台作为从站，但在组态完成之后，再NETPRO里进行编译时，出现警告：
Outputs for station ’Maste Station’:
Warning:Attention:in station Slave Station there are additional nodes that alse have to be reloaded.
Outputs for station ’Slave Station’:
Warning:Attention:in station Master Station there are additional nodes that alse have to be reloaded.
(我将两个站的名字分别叫作Master Station和Slave Station)
然后在硬件进行download时CPU就开始出现错误，SF灯一直亮着。在线模式下，主站和从站CPU的Diagnostic Data所显示的事件均为：
Distributed I/Os: end of the synchronization with a DP master
Slot of the DP master: 2
Number of distributed stations: 0
Incoming event
反复调试，总无法解决，希望大虾帮忙解决之，最好能有详细的调试步骤，因本人已陷入僵局。
