最佳答案
Cycle time exceeded
Run time of the last cycle (ms): 6000
Cause: OB1 start event initiated by end of warm restart
Causing OB: Cyclic program (OB1)
上述信息表明有循环时间超时的错误,检查OB1中程序是否有死循环的现象。
Timing error OB (OB80):
在诊断信息描述中调用了OB80。
OB80 :时间故障。可能的原因:
这样的故障包括: 循环时间超出、执行OB 时应答故障、向前移动时间以致于跃过了OB 的启动时间、CiR 后恢复RUN 方式。如果,例如,当循环中断OB 仍在执行前一次调用时,该OB 块的启动事件发生,操作系统调用OB80。如果OB80 未编程,CPU 变为STOP 方式。您可以使用SFC39 至42 封锁或延时和再使能时间故障OB。
注意:如果在同一个扫描周期中由于扫描时间超出OB80 被调用两次,CPU 就变为STOP 方式。您可以通过在程序中适当的位置调用SFC43“RE_TRIGR ”来避免这种情况。
