Causing OB: Cyclic interrupt OB (OB  37)
循环中断错误
Requested OB: Timing error OB (OB80)
需要下载OB80块
原因：估计是你在OB37中的程序太多，运算时间超出了OB37的中断时间。
解决办法：
1、精简OB37中的程序
2、将OB37中的程序放到OB35中
3、下载OB80块，CPU会报错，但不会停机

STOP caused by time error (OB not loaded, or not possible, or no FRB)
Causing OB: Cyclic interrupt OB (OB  37)
从上述诊断信息来看，你的程序中应用了信号中断组织块B  37。S7-PLCSIM仿真器不能仿真时间中断，即S7-PLCSIM仿真器不能完全仿真一个“真实的”自动化控制系统。
