=0, and trigger RS [0] will be opened and be set to 0, RS [0]=0, and breakdown judge trigger RS [3] will be opened and be set to 0, RS [3]
=0, and failure will be opened and be set to 0, OpenFail=0, and operating trouble OPFL is set to 0, OpFL=0, and by operating trouble
Judge that the timer time is set to 0, OpflTime=0；
(2) closing fault judges
Judge that trigger RS [4] has exported 1 when meeting closing fault, i.e. when RS [4]=1 condition, into closing fault
Deterministic process:
Firstly, when operating trouble timer time OpflTime is greater than device travel time OverT and stops feeding back Fb2
It is 0, then closing fault CloseFail is set to 1 i.e. CloseFail=1, while operating trouble OpFL is set to 1 i.e. OpFL=
1, while the operating trouble timer time is set to 0 i.e. OpflTime=0；
Secondly, each execution cycle, judges whether operating trouble OpFL is 0, if it is 0, when operating trouble timer
Between the OpflTime automatic accumulating operation period time dt；
Finally, having come if stopping feedback, i.e. Fb2=1, then following operation is performed simultaneously by halt instruction and is reset to 0, Dmd2
=0, and trigger RS [1] will be closed and be set to 0, RS [1]=0, and closing fault is judged that trigger RS [4] is set to 0, RS [4]
=0, and closing fault is set to 0, CloseFail=0, and operating trouble OpFL is set to 0, OpFL=0, and by operating trouble
Judge that the timer time is set to 0, OpflTime=0；
(3) failure is cleared up
