Short Name: StaticChannels

Property of niHSDIO

Configures channels for static operation. The group of static channels is reconfigured each time this property is set. For example, setting this property to 0-10 and then setting it to 5-8 results in only channels 5-8 being assigned to static. Channels 0-4 and 9-10 are unconfigured by the second configuration. Writing an empty string to this property configures ALL channels for static. Writing the value None unconfigures all channels for static. The channel is not configured or unconfigured until you call the niHSDIO Read Static (U32) VI, the niHSDIO Write Static (U32) VI, the niHSDIO Read Static PFI (U32) VI, or the niHSDIO Write Static PFI (U32) VI.

You can configure a channel for more than one simultaneous operation. A channel can be simultaneously configured for the following operations:

  • Dynamic generation and any (static and/or dynamic) acquisition
  • Static generation and any (static and/or dynamic) acquisition
  • Both static and dynamic acquisition
Note  You cannot configure a particular channel for simultaneous dynamic and static generation.

Unconfiguring a static generation channel frees that channel to be reconfigured for dynamic generation. Unconfiguring a static generation channel does not stop the channel from driving its current value - any static value already written to the channel continues to be driven.

Syntax examples:

  • 2-15 or 15-2 set channels 2 through 15 for static operation
  • 0-3, 5, 8-15 set channels 0-3, 5, and 8-15 for static operation
  • 0, 3, 10 or 3, 10, 0 set channels 0, 3, and 10 for static operation
  • "" (empty string) sets ALL channels for static operation
  • None removes all channels from static operation
