add - Add entry to IVI configuration store object

Syntax

Arguments

obj	IVI configuration store object
'DriverSession' 'HardwareAsset' 'LogicalName'	Type of entry being added
'name'	Name of the DriverSession, HardwareAsset, or LogicalName being added
'IOResourceDescriptor'	Tells the driver exactly how to locate the device this asset represents
'ModuleName'	IVI instrument driver or software module
'HardwareAssetName'	Unique identifier for hardware asset
'SessionName'	Unique identifier for asset driver session
'P1'	First optional parameter for added entry. Other parameter-value pairs may follow.
V1	Value for first parameter
struct	Structure defining entry to be added; field names are the entry parameter names

Description

add(obj, 'type', 'name', ...) adds a new entry of type to the IVI configuration store object, obj, with name, name. If an entry of type, type, with name, name, already exists an error will occur. Based on type, additional arguments are required. type can be HardwareAsset, DriverSession, or LogicalName.

add(obj, 'Driversession', 'name', 'ModuleName', 'HardwareAssetName', 'P1', V1) adds a new driver session entry to the IVI configuration store object, obj, with name, name, using the specified software module name, ModuleName and hardware asset name, HardwareAssetName. Optional parameter-value pairs may be included.

Valid parameters for DriverSession are listed below. The default value for on/off parameters is off.

Parameter	Value	Description
Description	Any string	Description of driver session
VirtualNames	structure	A struct array containing virtual name mappings
Cache	on/off	Enable caching if the driver supports it.
DriverSetup	Any string	This value is software module dependent
InterchangeCheck	on/off	Enable driver interchangeability checking, if supported
QueryInstrStatus	on/off	Enable instrument status querying by the driver
RangeCheck	on/off	Enable extended range checking by the driver, if supported
RecordCoercions	on/off	Enable recording of coercions by the driver, if supported
Simulate	on/off	Enable simulation by the driver

add(obj, 'HardwareAsset', 'name', 'IOResourceDescriptor', 'P1', V1) adds a new hardware asset entry to the IVI configuration store object, obj, with name, name, and resource descriptor, IOResourceDescriptor. Optional parameter-value pairs may be included.

Valid parameters for HardwareAsset are

Parameter	Value	Description
Description	Any string	Description of hardware asset

add(obj, 'LogicalName', 'name', 'SessionName', 'P1', V1) adds a new logical name entry to the IVI configuration store object, obj, with name, name, and driver session name, SessionName. Optional parameter-value pairs may be included.

Valid parameters for LogicalName are

Parameter	Value	Description
Description	Any string	Description of logical name

add(obj, struct), where struct is a structure whose field names are the entry parameter names, adds an entry to the IVI configuration store object, obj, of the specified type with the values contained in the structure.

Additions made to the configuration store object, obj, can be saved to the configuration store data file with the commit function.

Examples

Construct IVI configuration store object, c.

c = iviconfigurationstore;

Add a hardware asset with name gpib1, and resource description GPIB0::1::INSTR.

add(c, 'HardwareAsset', 'gpib1', 'GPIB0::1::INSTR');

Add a driver session with name S1, that uses the TekScope software module and the hardware asset with name gpib1.

add(c, 'DriverSession', 'S1', 'TekScope', 'gpib1');

Add a logical name to configuration store object c, with name MyScope, driver session name S1, and description A logical name.

add(c, 'LogicalName', 'MyScope', 'S1', ...
'Description', 'A logical name');

Add a hardware asset with the name gpib3, and resource description GPIB0::3::ISNTR.

s.Type = 'HardwareAsset';
s.Name = 'gpib3';
s.IOResourceDescriptor = 'GPIB0::3::INSTR';
add(c, s);

Save the changes to the IVI configuration store data file.

commit(c);
