想看plc中的程序,通过在线连接,在上位机建立一个与plc的cpu相匹配的项目后,设置online,可以看到plc中的各块,但双击某块时,出现警告:There are no parameter and local variable names available because there is a time stamp conflict between the interface of the block and the descrition of the parameter and local variable names.确定以后,又出现:The online opend block and the associated block in the offline adta management are different.
小弟尚处学习阶段,看手册也没弄明白。请有经验的各位指点一下,该怎么样能消除呢,谢谢了
