Example 2: Smart Belt

The preset value of this step = 20000 ms. The step
turns on its DN bit if it doesn’t clear the faults
within 20000 ms.

If Step_000.DN = on, a timeout happened. When a timeout happens, the OSR instruction
turns on the Clear_Faults_Timeout bit for one scan.

If MyPhase is in the resetting state and Clear_Faults_Timeout is on, then the PFL instruction
signals a failure. The PFL instruction sets the failure code = 501.
