Set Time Reference Multimode Function (1588 Ordinary Clock) (G Dataflow)

Version:
Last Modified: March 15, 2017

Sets the external time reference of the device to 1588 ordinary clock.

If the device is not a 1588 slave and you set the time reference to 1588 Ordinary Clock, the board time enters Free Running mode. Calling this function does not explicitly start the 1588 protocol. You must invoke Start 1588 after setting the time reference for the device to participate in 1588.

Note  
  • NI-Sync devices use the TAI timescale.
  • The servo may apply a macro phase adjustment when your device's board time and the external time reference varies by more than 1 ms. A macro phase adjustment adjust the external time reference by a significant amount, and the time no longer atomically increments. This should not occur on a well-designed and stable network. A macro phase adjustment may affect future time events, clocks, and timestamps. If the external time reference is set forward, future time events and clock transitions that were missed occur immediately. If the external time reference is set backward, future time events and clock transitions are delayed.

instrument handle in

The instrument handle that you obtain from Initialize.

error in (no error)

error in (no error) accepts error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

datatype_icon

status

status is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

datatype_icon

code

code identifies the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

datatype_icon

source

source specifies the origin of the error or warning. The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

datatype_icon

instrument handle out

The instrument handle that you obtain from Initialize.

error out

error out passes error or warning information out of a VI to be used by other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
