Phase Template: timed-wait¶

Wait for a specified duration, touching no equipment. Use it for reaction or mixing hold periods between device moves when composing custom recipes out of single-action building blocks. For example, open-valve → timed-wait → close-valve.

Where to find it¶

System endpoint → Equipment Library → Phases → select timed-wait.

See Phases for the diagram conventions.

What you see when it runs¶

Element	Meaning
Active step	`waiting` for the whole duration
Parameters	`duration` resolved from the recipe formula
Elapsed	Step-elapsed timer compared against `duration`

Parameters¶

Parameter	Type	Unit	Range	Default	Required
`duration`	TIME	—	`1s`-`1h`	—	yes

TIME parameters take duration strings ("45s", "1m30s", "5m"), not bare numbers.

Required control modules¶

None. The phase declares no control-module roles.

Capability: reaction.

How it works¶

It is a pure timer. waiting posts a start message, then the single transition waiting.T >= duration advances to done. All the procedural charts (holding, stopping, aborting, resetting) are no-ops. There is no equipment to safe-state. Restart restarts the timer from zero, discarding whatever elapsed before the hold interrupted it.

This is a timed phase in its purest form. The timer guarantees only that time passed. It says nothing about what the process did during that time. Whatever state the surrounding steps left the equipment in persists through the wait, so the alarms that matter are the ones paired with those neighboring steps.

Used in recipes¶

No shipped reference recipe uses this template. It is a building block for composing your own.

Try it¶

System endpoint → Recipes → create a draft recipe with a timed-wait step between two device moves on any unit
Approve and start it from HMI endpoint → Batch Execution
Click into the phase and watch the step-elapsed timer count up to duration
