Wash Cycle

hard

Runs Fill, Mix, and Drain actuators in order with pause, resume, and reset controls.

What it teaches

Combine state, retentive phase timers, and real actuator outputs. Pause saves elapsed time but turns every actuator off; Resume continues the same phase.

Parameters

Tag	Direction	Type	Default	Description
In_Start	Input	BOOL	0	Starts a new cycle from Idle
In_Pause	Input	BOOL	0	Pauses the active phase
In_Resume	Input	BOOL	0	Continues a paused phase
In_Reset	Input	BOOL	0	Aborts the cycle and returns to Idle
Cfg_FillTime	Input	DINT	2000	Fill duration in milliseconds
Cfg_MixTime	Input	DINT	3000	Mix duration in milliseconds
Cfg_DrainTime	Input	DINT	2500	Drain duration in milliseconds
Out_FillValve	Output	BOOL	0	Opens during the active Fill phase
Out_Mixer	Output	BOOL	0	Runs during the active Mix phase
Out_DrainValve	Output	BOOL	0	Opens during the active Drain phase
Sts_State	Output	DINT	0	0=Idle, 1=Fill, 2=Mix, 3=Drain
Sts_Paused	Output	BOOL	0	1 while phase timing and actuators are paused

Required behavior

A new Start press in Idle begins Fill. The cycle then advances to Mix, Drain, and back to Idle after each configured duration.
Only the actuator for the current phase is on. All three actuators are off in Idle.
A Pause press freezes the current phase timer and turns all actuators off. Resume continues the same phase from its saved elapsed time.
Start is ignored outside Idle. Pause is ignored in Idle. If Pause and Resume are pressed together, Pause wins.
Reset wins over every other command, turns all actuators off, clears Pause, and makes the next Start begin a fresh Fill.
