现在有两个轴，每个轴包含了启停、measuring input、output cam等功能，现在想让这两个轴的这些功能可以同时开始运行。
帮助文件里对Synchronous start的说明是“You can use this command to start several commands simultaneously” 同时也说明“When you use the Synchronous Start command, you must generate the UserInterruptTask_1 since this is called in the event of an error. You can program an error response in this task.”
现在我使用这个结构时CPU无法从STOP变到RUN。请教高人们该如何解决这个问题啊？！UserInterruptTask_1中的程序有特殊要求吗？我现在只放了一个空程序，另外，SystemInterruptTasks中我也都已经放了空程序。
