Routes the input trigger from the front or rear connector to a trigger bus line (TTLx).

This node should be used when scanning a module in a different NI-SWITCH session that is not directly cabled to the trigger source (multimodule scanning operations).

Programming Patterns

If this node is used to route a trigger to a TTL line, specify the TTL line as the trigger input in the niSwitch Configure Scan Trigger node.

invert

Boolean input that reverses the input trigger signal from rising to falling and falling to rising.

TRUE Reverses the input trigger signal.
FALSE Does not reverse the input trigger signal.

Default: FALSE (0)

session in

Control that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node.

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

trigger input connector

Location of the input trigger source on the switch module. Valid locations are the front and rear connectors.

Default: Front Connector

datatype_icon

trigger input bus line

Trigger line that routes the input trigger. Select None to break an existing route.

datatype_icon

session out

Indicator that identifies a particular NI-SWITCH session established with the niSwitch Initialize With Topology node, the niSwitch Initialize With Options node, or the niSwitch Initialize node and used for all subsequent NI-SWITCH calls.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Disconnecting Routes

To disconnect the route, call this node again and select None for the trigger input bus line parameter.

Where This Node Can Run:

Desktop OS: Windows
