如果要向PLC写数据,比如在系统运行时要改变某一个参数。原先在CPT中可以将PLC从运行方式转到编程方式,再修改某数据区的值(比如PID指令的参数)。但在InTouch的WindowView下,好像不能进行PLC的操作模式的切换。而InTouch OMRON Host Link IO server手册上说“The result will be unpredictable if OMRON Host Link I/O Server is writing to discrtes which are also being used in a ladder logic prgram.… (page38)”。这该怎么处理?
