If the operator presses the start button on the machine or HMI, then
My_Inputs.AnyStartPressed = on for 1 scan.
The ONS instruction makes sure that My_Inputs.AnyStartPressed turns on only

 on.
If the equipment phase is in the idle state and My_Inputs.AnyStartPressed = on, then
The PCMD instruction gives MyPhase the start command.
