Agilent VWorks Driver Page#

This page has all the information specific to the Agilent VWorks driver and adapter.

Supported Agilent VWorks versions#

Agilent VWorks 13.1

Agilent VWorks Installer#

You can download the latest installer here.

Agilent VWorks Adapter pyproject.toml Dependencies#

Add the needed dependencies to the [project] section of pyproject.toml by running the below in your terminal:

uv add artificial-vworks-adapter==1.1.*

Your pyproject.toml file should now include artificial-vworks-adapter in the project dependencies section:

[project]
dependencies = [
  "artificial-vworks-adapter==1.1.*",
]

Agilent VWorks Adapter config.yaml File#

config.yaml#
adapter:
  name: VWorksTutorialAdapter
  remoteConfig: False
  allowAnySequenceId: True # Useful when running in a local dev container
  plugin: # all resources this adapter can connect to
    resource:
      name: "Bravo"  # user friendly name, unique in the adapter
      id: "bravo" # This should match the device key in the asset_sync section below
      driver:
        name: "vworks" # Driver name, this is a non-configurable string that needs to match the driver identity
        url: "http://vworks.webaddress.com:49835" #  URL of the hardware and driver
        resource_simulation: false     # Set to true to run simulation without hardware
        driver_simulation: false       # Set to true to run simulation without a driver
        cert_file: "adapter/certs/ca.crt"
        user_name: ""
        user_password: ""
  asset_sync:
    devices: # device string names/prefix must match resource id above
       "bravo": { rid: "d1234567-34d0-4391-be64-7aef4e0b28be" }

  1. Fill in the correct URL (including the port) for the VWorks device. The device’s IPv4 URL can be obtained from Network & Internet Settings or by running ipconfig in a command window. The port is listed in the running driver server console window.

    Where to find the port number in the driver console window

  2. You may update the resource name above if you wish. Any string will work but it must be unique across the instance.

  3. Fill in the user_name and password if needed.

  4. If you wish to run in simulation without hardware or without a driver, change resource_simulation or driver_simulation to true, respectively.

  5. Update the asset_sync section to map the resource id to the instrument’s asset instance id in the digital twin. You can fill out the rest of the devices later. See Asset Sync Config for more information.

Agilent VWorks Simple Connectivity Workflow#

This workflow will run a method of your choosing and log a message in the UI upon successful completion. You will define which method to run in the request UI by inputting the method name with its full path (e.g., C://Methods//mymethod.med).

A couple of notes: #. After copying this code into a file, remember to replace the lab_guid in the workflow heading with the one from your Lab (most easily found by opening the Lab in Artificial and looking in the browser address bar). Consult Adding and Running a Simple Connectivity Test Workflow for more info.

  1. Update the variable section to reflect your protocol as you may have different variables or none.
