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

Last Modified: August 28, 2017

Set the external time reference of the device to PPS (pulse per second).

Note  

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 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.

datatype_icon

instrument handle in

The instrument handle that you obtain from Initialize.

datatype_icon

use manual time

A Boolean value that specifies whether or not to use the user-supplied time or the OS system time to represent the time at which the first pulse is received.

False Reads the OS system time when the first pulse is received and uses that time to set the board time.
True Uses the user-specified initial time to set the board time when the first pulse is received.
datatype_icon

terminal

The terminal on which the PPS signal is supplied.

datatype_icon

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

initial time

The value to set the board time to when the module receives the first pulse. Only use this terminal if you set use manual time to True.

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.

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.
