Zero-Touch Deployment of PXI Controllers Using Ansible

Why Automate PXI Deployment?

PXI-based test systems are often deployed across production lines, labs, and remote validation setups. Manual setup of each PXI controller—installing drivers, configuring static IPs, deploying LabVIEW runtimes or Python packages—can waste hours. Ansible solves this via **zero-touch deployment**, ensuring every system is consistently configured and production-ready.

What Is Ansible?

Ansible is an agentless IT automation engine that uses YAML playbooks over SSH or WinRM. It’s ideal for configuring PXI controllers running Windows or Linux RT, managing updates, installing software, and applying configuration changes programmatically. You don’t need to install any agent on the PXI side—just enable SSH or WinRM and connect from a control machine.

Zero-Touch PXI Setup: Key Workflow

Here’s a typical zero-touch PXI provisioning pipeline:

1. PXI unit receives DHCP lease or static IP
2. SSH or WinRM access configured via boot image or PXE
3. Ansible playbook connects and pushes configuration
4. Software installed: LabVIEW Runtime, NI-VISA, Python, packages
5. Test agent registered with CI/CD or MES

Unattended deployment requires a preconfigured boot image, network access, credentials, compatible software, and a tested recovery procedure; connecting a rack alone does not provide these prerequisites.

Sample Ansible Playbook for PXI Controller

This file-deployment example requires the ansible.windows collection, a configured pxi_windows inventory, working authenticated WinRM, and a reviewed files/test_agent.py on the control machine. It neither installs NI drivers nor starts the agent. Configure the network separately: win_dns_client changes DNS servers, not the adapter IP address. Use the supported installation procedure and silent-install arguments for the exact NI software release.

- name: Deploy a reviewed test-agent file to Windows PXI controllers
  hosts: pxi_windows
  gather_facts: false
  tasks:
    - name: Verify the Windows connection
      ansible.windows.win_ping:
    - name: Ensure the destination directory exists
      ansible.windows.win_file:
        path: 'C:\Test'
        state: directory
    - name: Copy the reviewed agent without starting it
      ansible.windows.win_copy:
        src: files/test_agent.py
        dest: 'C:\Test\test_agent.py'
        backup: true

Supported PXI OS Types

Ansible supports:

• Windows-based PXI controllers (PXIe-8880, PXIe-8840, etc.) via WinRM
• NI real-time targets: verify the exact controller, operating-system release, SSH support, Python availability, and supported deployment method before using Ansible modules. This Windows example does not establish Linux RT compatibility.

Windows controllers may require enabling WinRM and firewall rules; Linux targets need SSH and sudo access.

Best Practices for Zero-Touch Provisioning

• Use PXE boot with preconfigured image (or golden image USB stick)
• Use SSH keys or secure credentials vault (e.g., Ansible Vault)
• Store inventory and playbooks in Git for version control
• Run playbooks after every hardware replacement or test plan change

Using tools like GitLab CI/CD or Jenkins, you can even automate PXI provisioning as part of your factory deployment pipeline.

Integration with Test Environments

Ansible can also trigger LabVIEW EXEs, Python scripts, or configure system services to launch your test software on boot. With DAQ & Control modules or completion hardware, PXI units become fully autonomous test machines on the first power-up.

FAQs

Can I deploy PXI software updates with Ansible?

Yes. You can push software, patches, and registry settings remotely.

Is it safe for production labs?

Yes, with secure credential handling and read-only playbooks for sensitive targets.

What if the PXI controller fails?

Provision a new one identically in minutes using the same playbook.
