Set Time Reference Multimode Function (IRIG) (G Dataflow)

Version:
Last Modified: August 28, 2017

Sets the external time reference of the device to IRIG-B AM or IRIG-B DC.

You must have an external IRIG source connected to the specified terminal for this mode to function.

Note  

The servo may apply a macro phase adjustment when the device's board time and the external time reference varies by more than 1 ms. A macro phase adjustment adjusts 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.

IRIG type

The type of IRIG output generated by the external IRIG source.

Name Description
IRIGB DC The IRIG-B DC output.
IRIGB AM The IRIG-B AM output.

terminal

The terminal on which to enable IRIG as the time reference.

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.

datatype_icon

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.

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.
