The Set Relays tab contains the following options:

  • Relay or Relay Configuration Name—Specifies the relay or relay group that you want to control, or the relay configuration that you want to apply. Relays, relay groups, and relay configurations must be defined in the pin map file.

    Select the Edit Pin Map button next to the input field to launch the Pin Map Editor and edit relays, relay groups, and relay configurations in the pin map file.

    Initialize NI-SWITCH relay driver sessions for all relay driver modules in the pin map file and register these sessions with the Set Relay Driver NI-SWITCH Session VI or the SetRelayDriverNISwitchSession .NET method.

  • Relay Action—Specifies how you want to set the relays. Valid options include:
    • Apply Relay Configuration—Applies the relay configuration specified in Relay or Relay Configuration Name. Relays are opened or closed according to the relay position specified in the relay configuration.

      This option is only valid if Relay or Relay Configuration Name specifies a relay configuration.

    • Open Relays—Opens the relays specified in Relay or Relay Configuration Name. If Relay or Relay Configuration Name specifies a relay group, all relays in the group are opened.

      This option is only valid if Relay or Relay Configuration Name specifies a relay or relay group.

    • Close Relays—Closes the relays specified in Relay or Relay Configuration Name. If Relay or Relay Configuration Name specifies a relay group, all relays in the group are closed.

      This option is only valid if Relay or Relay Configuration Name specifies a relay or relay group.

  • Time to wait (in seconds)—Specifies the time to wait for the relays to settle after switching.
