Remarks
A task can contain global or local channels. Global channels are accessible to all tasks on the system. Local channels are accessible only to the task you use to create them.
Use local channels in a typical application. Use the create channel methods on AIChannels, AOChannels, DIChannels, DOChannels, CIChannels, or COChannels to create local channels and add them to the task. Use Measurement & Automation Explorer (MAX) to create, configure, and store global channels.
