Create Clock Multimode Function (Ticks) (G Dataflow)

Version:
Last Modified: March 15, 2017

Generates a clock synchronized to the board time associated with the specified instrument handle. This clock runs for a specified number of high and low ticks every cycle.

The terminal associated with this clock cannot be used for other operations until the clock is cleared with Clear Clock or the session is closed with Close. When this function is invoked, the digital signal on the specified terminal is driven low until the clock starts.

low ticks

The number of ticks the generated clock should spend in the low logic state.

You can view the length of a tick using the Clock Resolution property of niSync Properties.

Default: 100

datatype_icon

high ticks

The number of ticks the generated clock should spend in the high logic state.

You can view the length of a tick using the Clock Resolution property of niSync Properties.

Default: 100

datatype_icon

instrument handle in

The instrument handle that you obtain from Initialize.

datatype_icon

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

datatype_icon

terminal

The line you would like to generate the clock on.

You cannot use this line for other operations until you clear the generated clock using Clear Clock or close the session.

datatype_icon

start time

The time to start the generated clock.

This time is synchronized with the board time of the module you use to create the clock.

Default: immediate

datatype_icon

stop time

The board time when to stop the generated clock.

This time is synchronized with the board time of the module you use to create the clock.

Default: never

datatype_icon

instrument handle out

The instrument handle that you obtain from Initialize.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
