VISA Shared Components 7.2
The VISA Shared Components are typically installed when installing a VISA library from a specific vendor. For instance, if you wish to use an IVI driver in simulation mode, you can install the VISA Shared Components without having a full VISA library on your system.

Visa shared components что это
The IVI Shared Components are owned and distributed by the IVI Foundation. These components form the underlying structure of an IVI-compliant system. An IVI-compliant piece of software follows the specifications set by the IVI Foundation, allowing it to be easily used with other IVI-compliant drivers and software.
Because the IVI Compliance Package components are designed to work with the IVI Shared Components, the IVI Shared Components are installed as part of the IVI Compliance Package.
To uninstall the IVI Shared Components, uninstall the IVI Compliance Package following the instructions in Installing, Updating, Repairing, and Removing NI Software.

Kelary. Ivi. Visa 5.11.3422
In traditional approach VISA.NET Shared Components distributed only as part of a vendor’s installer for its VISA implementation. This approach requires installation of vendor’s VISA library implementation on build server even if communication with instruments is not needeed on this stage.
If developed application assumed to work with various third-party VISA implementations and no VISA libraries were installed it would be nice if it could provide only a part of the functionality or report VISA library neccesarity.
IVI Foundation Releases IVI Shared and VISA Shared Components for 64-Bit Vista
The IVI Foundation announces the release of the 64-bit IVI Shared Components and VISA Shared Components. This release enables vendors to provide 64-bit VISA and IVI drivers to test and measurement customers. In addition, a VISA Router and VISA Conflict Resolver were added to the VISA Shared Components and a C API for the IVIConfigServer to the IVI Shared Components.
“The release of these components keeps the IVI standards aligned with evolving industry standards and customer requirements,” said Jon Bellin, chairperson of the IVI 64-bit working group. “64-bit is an emerging requirement and the updates to these components permit IVI vendors to provide 64-bit VISA or IVI solutions.”
In addition to providing support for usage on 64-bit Vista, the VISA Shared Components also include a VISA Router and a VISA Conflict Resolver. Now, users can easily create solutions with I/O hardware and software from various vendors.
Previously, a user had to specify which VISA was primary and then configure all the instrument communications to route through that VISA. When I/O hardware used in a system was provided by more than one vendor, it was possible for two different I/O devices to be assigned the same address, resulting in a conflict that would generate a VISA error.
With the introduction of the VISA Router, a user no longer has to identify one VISA as primary but can use the VISA of choice. The VISA Conflict Resolver will automatically detect and notify the user if a conflict exists between two different I/O devices. This allows the user to identify and correct the problem immediately, before developing applications using the erroneous information.
In conjunction with the release of the IVI Shared Components, a C API has been provided for the IVIConfigServer. This allows customers who use IVI-C drivers to use native C interfaces instead of COM when using the Config Server.
About Shared Components
The IVI Foundation provides a standard set of shared components required by all compliant drivers and ancillary software. These components provide common services to drivers and driver clients; the administration of system-wide configuration is an example. The IVI Shared Components are required when using an IVI driver. The VISA Shared Components are used with a VISA library from a specific vendor.
