我组建了一个以s7-400为主站，D435位从站的系统，但是设置完成后，用Netpro编译时，老是提示2个报警，
第一个：output for station"simatic 400(1)"
warning warning:caution:in station simotion D there are additonal nodes that also have to be reloaded
第二个：output for station"simotion D"
warning warning:caution:in station simatic 400(1) there are additonal nodes that also have to be reloaded

请问那位高人可以指点一下！！
