PXI is designed for measurement and automation applications that require high-performance and a rugged industrial form-factor. With PXI, one can select modules from a number of vendors and integrate them into a single PXI system, over 1150 module types available in 2006. A typical 3U PXI module measures approximately 100 x 160 mm (4x6") in size, and a
PC cards are typically used to expand a system's embedded applications. PC cards include modules for audio and video applications, data communications and embedded storage. PXI cards are used for data acquisition and control systems, making them suitable for real-time measurement applications.
Instrumentation: PXI, VXI, LXI, GPIB, SCXI, and PCI Electronic equipment that generates or analyzes I/O. Cable Assemblies and Receiver Patchcords: Modules connect to the instrument-specific connector(s) and are also available in PCB adapter configurations that accept COTS (commercial off-the-shelf) cable assemblies.
PXI is a peripheral bus specialized for data acquisition and real-time control systems. Introduced in 1997, PXI uses the CompactPCI 3U and 6U form factors and adds trigger lines, a local bus, and other functions suited for measurement applications. PXI hardware and software specifications are developed and maintained by the PXI Systems Alliance ...
Introduced in 1997, PXI uses the CompactPCI 3U and 6U form factors and adds trigger lines, a local bus, and other functions suited for measurement applications. PXI hardware and software specifications are developed and maintained by the PXI Systems Alliance. [5] More than 50 manufacturers around the world produce PXI hardware. [6]
Of equal or greater importance in the support of the mezzanine is the software. The majority of the M-Module instrument types referenced above come with VXI/PXI Plug-and-Play or IVI drivers. However, a number of the more control oriented M-Modules are supported only with C drivers.
These are defined by PICMG 2.0R3 and PICMG Exp0 R1 respectively. Other computer architectures that utilize the Eurocard system are VME eXtensions for Instrumentation (VXI), PCI eXtensions for Instrumentation (PXI), and PXI Express. A computer architecture that used the 6U-220 Eurocard format was Multibus-II, which was IEEE 1296.
Within the dataway, modules are addressed by slot (geographical addressing). The left-most 22 slots are available for application modules while the right-most two slots are dedicated to a crate controller. Within a slot the standard defines 16 subaddresses (0–15). A slot commanded by the controller with one of 32 function codes (0–31).
