The NI-SWITCH API offers the following three triggering schemes for scanning.

  • Software trigger scanning
  • Synchronous scanning
  • Handshaking

Refer to the switch module documentation in Devices to determine if the switch module supports scanning.

Refer to Software Trigger Scanning for information on programming software triggers using NI-SWITCH. If you are scanning NI switches with an NI DMM, and you are using NI-SWITCH and NI-DMM APIs, refer to Scanning NI Switches with NI Digital Multimeters.
Note   Some devices may not support scanning. Refer to your device book for more information about supported features.
