Settings Name is the name of the configuration settings, such as Default 7330 Settings, specified in Measurement & Automation Explorer (MAX). To use the current configuration settings, leave Settings Name unwired or pass NULL for the Settings Name parameter. The current settings are the settings that are configured in MAX.
Board ID is a unique number assigned by Measurement & Automation Explorer (MAX) used to send and receive commands and data to or from a specific NI motion controller.
error in (no error) describes error conditions that occur before this VI runs. The default input of this cluster is no error. If an error already occurred, this VI returns the value of error in in error out. The VI runs normally only if no incoming error exists. Otherwise, the VI passes the error in value to error out. The error in cluster contains the following parameters:
status is TRUE if an error occurred before this VI was called, or FALSE if not. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code.
code is a number identifying an error or warning. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code. Use the error handler VIs to look up the meaning of this code and display the corresponding error message.
source is a string that indicates the origin of the error, if any. Typically, source is the name of the VI in which the error occurred.
Bd ID Out is provided for flow control. You can string together NI-Motion VIs by wiring the Bd ID Out terminal of one VI to the Board ID terminal of the next VI.
error out contains error information. If error in indicates an error, error out contains the same error information. Otherwise, it describes the error status that this VI produces.
status is TRUE if an error occurred, or FALSE if not. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code.
code is a number identifying an error or warning. If status is TRUE, code is a nonzero error code. If status is FALSE, code is zero or a warning code. Use the error handler VIs to look up the meaning of this code and display the corresponding error message.
source is a string that indicates the origin of the error, if any. Typically, source is the name of the VI in which the error occurred.

Using This VI

This VI allows you to initialize the controller to a known state based upon the configuration settings stored in the Measurement & Automation Explorer database. This VI pulls values from the configuration database and calls dozens of NI-Motion VIs, configuring the controller for you in one simple step.

If the Initialize Controller VI returns an error, you can call the Get Last Error VI to determine the specific NI-Motion VI and resource generating the error. You can then call the Get Error Description VI, which formats a string for you with the VI name, resource ID, and error description.

Note  If you are running a NI-Motion startup application on ETS (PharLap) systems, the first VI in your application must be either the Clear Power Up Status or Initialize Controller VI. Calling any other VI first may result in error –70012 (NIMC_badBoardIDError) because the driver may not have loaded before a NI-Motion VI is called.
Note  Refer to VI Execution Times for benchmark timing information about your controller.
