The option string parameter contains an entry with an unknown option value. The option string parameter contains an entry with an unknown option name. The option string parameter contains an entry without a value. The option string parameter contains an entry without a name. The channel has already been excluded for the specified attribute and cannot be re-included. The specified attribute is not channel– or repeated capability–based. This operation requires a channel– or repeated capability–based attribute. The attribute is not valid for the specified channel or repeated capability. The channel or repeated capability name is not allowed. The VirtualChannelNames item in the configuration file contains a virtual channel name that is assigned to an unknown or invalid channel string.Ĭhannel or repeated capability name required. The VirtualChannelNames item in the configuration file contains a virtual channel name without an assigned channel string (i.e., nothing after '='). Channel names must contain only alphanumerics, underscores, or an exclamation point. The VirtualChannelNames item in the configuration file contains an invalid virtual channel name. The VirtualChannelNames item in the configuration file contains an entry without a virtual channel name (nothing before the '='). The VirtualChannelNames item in the configuration file contains a duplicate virtual channel name. The channel or repeated capability list contains two instances of the same name.

The instrument driver must call Ivi_BuildChannelTable in its IviInit function.Ĭhannel or repeated capability name specified is not valid for the instrument. No channel table has been built for the session. The class instrument driver has encountered underspecified instrument configurations that limit interchangeability. There is no range table for this attribute.Ī connection to the instrument has not been initialized. The requested attribute value not known and cannot be determined. The requested item or value does not exist or is not available. The specified attribute already has a value waiting to be updated. The attribute and function parameter types do not match. The enumeration value for the parameter is not supported. Call the ClassPrefix_error_query function and examine the error.Ĭannot open driver module file for reading.ĭriver module has invalid file format or contains invalid data.ĭriver module contains undefined references. The following tables contain the IVI Status Codes, the Common Status Codes, and the most commonly used VISA Status Codes.

The following table lists the base values.ĭefault Values of Defined Constants Status Code Typeįor example, if you pass an invalid attribute ID to an IVI engine function, the function returns IVI_ERROR_INVALID_ATTRIBUTE, which ivi.h defines as IVI_ERROR_BASE + 12, or 0xBFFA000C.

The IVI engine and instrument driver include files define particular status codes as the unsigned sum of a base value and a decimal integer value. The status codes values for one driver can overlap the status code values for other drivers. Each particular instrument driver defines its own set of Driver Errors and Warnings. They provide a consistent set of codes for error and warning conditions that are common among all instrument drivers.

The Common Errors and Warnings are values that VXI plug&play defines and that specific instrument drivers return. The table lists the include files that contain the defined constants for the particular status codes. The following table defines the different ranges of status codes. Most-Often-Encountered VISA Errors and Warnings Status Code TablesĬommon Instrument Driver Errors and Warnings Regardless of the source of the status code, 0 always indicates success, a positive value indicates a warning, and a negative value indicates an error. Each set of status codes has its own numeric range. Still others are error or warning values that functions in specific instrument drivers return. Other status codes are the same codes that VISA Library functions return. Some status codes are unique to the IVI engine.

IVI engine functions can return error and warning values from several sets of status codes.
