Manage Device Sequences

A Device Sequence is a saved, ordered list of switching steps for the devices in an Assembly — for example, turn a device on, turn it off, or wait — that you trigger as one action instead of switching each device by hand. Use it to bring an Assembly into a defined hardware state, such as a power-cycle or reset routine, reproducibly.

When to use Device Sequences

  • To bring an Assembly's devices into a defined state before or after a test run — for example, power off Board X, wait, then power on Board Y.
  • To replace repetitive manual relay switching with a single, repeatable action.
  • To let a CI pipeline or a CANoe test trigger a defined switching routine through the API.

Jumpers are not part of Device Sequences

A sequence only switches devices on/off or waits — it cannot set jumpers. Jumper configuration is separate; see Relay Card & Jumpers.

Create a Device Sequence

Prerequisites

  • An Assembly you have access to manage
  • The device IDs of the devices you want to switch, listed in the Assembly Profile

Steps

1. Open the sequence dialog

Open the Create/Edit dialog for Device Sequences from the Assembly Dashboard view.

2. Name the sequence

3. Add the steps in the order they should run

Each step is one of:
  • Turn On / Turn Off — switch a single device, selected by its device ID
  • Turn All On / Turn All Off — switch every device in the Assembly
  • Wait — pause for a given duration before the next step

A Wait step takes a wait time, Turn On/Turn Off take a device ID — never both on the same step.

4. Set as default (optional)

Enable Set as default sequence to bind the sequence to the run button on the Assembly Dashboard view. Only one sequence per Assembly can be the default.

Run a Device Sequence

Prerequisites

  • A Device Sequence on the Assembly
  • The Assembly up and running — booked, with its HAI connection active

Steps

1. Start the run

Run the sequence from the Assembly Dashboard view, or use the run button for the default sequence. The current step and run status update live.

2. Cancel the run (optional)

A canceled sequence stops after the current step finishes.

Every referenced device needs a working HAI connection

If the Assembly is not running, or a device referenced by a step is not reachable through its HAI, the run fails on that step.

Troubleshooting

Symptom Likely cause Solution
Run fails immediately, no steps executed The Assembly is not up and running Make sure the Assembly is booked and its HAI connection is active, then retry.
Run fails on a specific step The device referenced by that step has no working HAI connection Check the device's connection in Assembly Monitoring, then retry.
A run stays in progress much longer than expected Another run is already active on the same virtual machine Runs on the same virtual machine are serialized — wait for the current run to finish, or cancel it.

Edit or Delete a Device Sequence

Edit a sequence's name, steps, or default flag in the same Create/Edit dialog you created it in.

Deletion cannot be undone

Deleting a sequence removes it permanently, including its run history.

API Reference

Device sequences are also available through the vHaaS REST API — see Device Sequences endpoints for the full list of operations, including creating, running, and canceling a sequence programmatically.

  • Assembly — the test setup a Device Sequence belongs to
  • Assembly Manager — controls devices directly from C# CANoe test code, instead of a sequence saved on the Assembly
  • Relay Card & Jumpers — jumper configuration, which Device Sequences do not cover
