session in

Instrument session obtained from the Initialize With Channels node.

error in

Error conditions that occur before this node runs.

With the following exception, the node responds to this input according to standard error behavior. This node runs normally even if an error occurred previously. If an error occurred before this node runs, the node passes the error in value to error out, and no errors that occur while this node runs are recorded. If an error occurs while this node runs and no error occurred previously, the node sets its own error status in error out.

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

error out

Error information.

The node produces this output according to standard error behavior.

Power output

If power output is enabled when you call this node, the output channels remain in their existing state and continue providing power. Use the Configure Output Enabled node to disable power output on a per channel basis. Use the Reset node to disable power on all output channels.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported
