MC Database Open.vi

Purpose

Opens a specified A2L Database.

Format

Input

DB path is a path to a A2L database file from which to get channel names. The file must use a .A2L extension. You can generate A2L database files with several 3rd party tools.

Error in is a cluster which describes error conditions occurring before the VI executes. If an error has already occurred, the VI returns the value of the error in cluster to error out. status is TRUE if an error occurred. This VI is not executed when status is TRUE. code is the error code number identifying an error. A value of 0 means success. A negative value means error: VI did not execute the intended operation. A positive value means warning: VI executed intended operation, but an informational warning is returned. For a description of the code, wire the error cluster to a LabVIEW error-handling VI, such as the Simple Error Handler. source identifies the VI where the error occurred.

Output

DB reference out is the task reference which links to the opened database file.

Error out describes error conditions. If the Error in cluster indicated an error, the Error out cluster contains the same information. Otherwise, Error out describes the error status of this VI. status is TRUE if an error occurred. code is the error code number identifying an error. A value of 0 means success. A negative value means error: VI did not execute the intended operation. A positive value means warning: VI executed intended operation, but an informational warning is returned. For a description of the code, wire the error cluster to a LabVIEW error-handling VI, such as the Simple Error Handler. source identifies the VI where the error occurred.

Description

Opens a specified A2L Database. MC Database Open.vi enables you to query all defined ECU names in the A2L Database using the MC Get Names.vi and selecting the property ECU Names. MC Database Open.vi does not start communication.

MC Database Open.vi is an advanced function for database handling. In most cases it is sufficient to use MC ECU Open.vi instead.
