RT Get Timestamp (G Dataflow)

Last Modified: January 12, 2018

Inserts a 64-bit timestamp value from a high-precision timing source into a preallocated array at an index value specified by iteration. The timestamp value indicates the time when the RT Get Timestamp node executes on the RT target.

Use the RT Timestamp Analysis node to analyze the timestamp array returned by the RT Get Timestamp node.

timestamp array in

Preallocated array used to store timestamps for each iteration of the RT Get Timestamp node. You must preallocate an array with enough elements to store all of the timestamps you want to collect.

iteration

Index value where the RT Get Timestamp node inserts the current timestamp in the timestamp array. Wire a loop iteration terminal to index the timestamps relative to their execution order.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

timestamp array out

Returns an array that contains a timestamp for each iteration of the RT Get Timestamp node.

error out

Error information.

The node produces this output according to standard error behavior.
