小弟调试机床840DSL 系统 时侯，一定要在WINSCP中执行 SC disable s_cycles， 才可以让机床启动。请问，这句指令有啥作用啊？？ 还有就是WINSCP 中类似的这种指令在哪可以查到啊？？
最佳答案
NCU的升级文件中摘录：
The "programGUIDE" (earlier, cycle support) in SINUMERIK Operate 2.6 SP1 is based on these cycle packages
2.6. Cycle calls in the part programs for these cycles cannot be re-compiled and processed with the cycle
support in HMI-Advanced 7.x. This also means that the simulation function in HMI-Advanced cannot be used. If
the cycle support of HMI-Advanced 7.x is to be used, then the cycle packages 7.x contained in HMI-Advanced -
should be downloaded into the NC after deactivating the cycles 2.6 with the service command "sc disable
s_cycles". This means that no SINUMERIK Operate operation is permissible.
就是说若用PCU50.3装了hmi advance，而你又非用hmi advance的程序模拟就需要装在pcu自带的循环和定义，而这就会和NCU中cf中自带的循环冲突，所以必须关闭NCU的循环。若用NCU或PCU上装的operate界面，你千万不能运行SC disable s_cycles，否则循环都无法使用。
