Deployment

Deployment refers to developing an application so that it can be distributed, or deployed, on a different computer than the one on which the application was developed. To deploy an application, you need the saved application and any configuration information the application and system requires.

When deploying an application, you must coordinate the use of configuration items that can be shared among multiple tasks. This includes devices, scales, and global virtual channels.

Developing Applications for Deployment

You can deploy NI-DAQmx applications in several ways:

• You can use the MAX Export Wizard to deploy an entire setup to another computer, including tasks, channels, scales, and devices.
• You can use the MAX Export Wizard to deploy an entire setup, except the device configurations, to another computer. You might choose to do this if the target computer already has tasks that rely on existing device configurations. In this case, you might have to make modifications after deployment so that your tasks and channels refer to the device configurations on the target computer.
• You can use the MAX Export Wizard initially to deploy a fixed set of device, scale, and global virtual channel configurations among a group of users. Each member of the group can create tasks that rely on the shared configurations, then create applications that use these tasks, and finally share the applications within the group. In some cases, the tasks deploy with the applications automatically. In other cases, you must deploy the tasks separately from the applications. Refer to the Deploying Tasks and Channels section for more information.

Deploying Tasks and Channels

Your tasks and channels deploy automatically with your application under the following circumstances:

• You use LabVIEW Express VIs for your DAQ applications.
• You save your tasks within a LabWindows/CVI or Measurement project, and the tasks use local channels only.
• You create your tasks and channels programmatically using the NI-DAQmx API.

You must deploy your tasks and channels using the MAX Export Wizard if you create your tasks and channels in the following ways:

• You create your tasks and channels directly in MAX.
• You create your tasks and channels in LabVIEW from the Task Name and Channel Name controls and do not generate configuration code.
• You create your tasks in LabWindows/CVI and neither generate configuration code nor copy the tasks to your project.
