Configure Initial State (Configure Initial State String) (G Dataflow)

Instrument session obtained from the Initialize Acquisition Session node, the Initialize Generation Session node, or the Initialize External Calibration node.

The channels being configured.

The initial state of a dynamic generation operation.

This expression is composed of characters:

• X or x—Retains the previous value.
• 1—Sets the channel to logic high.
• 0—Sets the channel to logic low.
• Z or z—Disables the channel or sets it to a high-impedance state.

The first character in initial state corresponds to the first channel in channel list. The number of characters in the pattern must equal the number of channels specified in channel list, or the node returns an error. For example, if you are trying to make three channels tristate, the idle state control needs to be "ZZZ" without any commas or spaces.

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

Handle that identifies the session in all subsequent node calls.

The session out parameter is obtained from the Initialize Acquisition Session node or the Initialize Generation Session node.
