Overview
Software
The National Instruments PXI-2576 is a multibank multiplexing module
with 16 banks of 4x1 2-wire multiplexers. With the flexible architecture
of the NI PXI-2576, you can configure it in a variety of topologies
that make it suitable for parallel measurement operations requiring
low-channel counts. In addition, you can combine all multiplexers on
the PXI-2576 to form a single high-channel-count multiplexer featuring
64 2-wire channels. The module can be programmed with a variety of
software including NI-SWITCH and NI Switch Executive.
All National Instruments PXI switch modules are shipped with
NI-SWITCH, an IVI-compliant driver offering complete functionality
for all switch modules. For additional assistance in configuring,
programming, and managing higher-channel-count switching systems,
NI Switch Executive software offers an easy-to-use, intelligent switch
management and visual routing environment. Use the NI-SWITCH
Soft Front Panel for simple relay operations or debugging
switch code/execution.
Automatic Scanning
The PXI-2576 maximizes throughput in automated test applications
using scanning. Scanning improves throughput by downloading a list
of up to 32,000 connections to the switch and cycling through the list
using an event (trigger) without any interruption from the host processor.
Scanning is most efficiently accomplished by mating the PXI-2576 with
an instrument, such as the NI PXI-4070 6 1⁄2 -digit FlexDMM, which issues
a trigger after each measurement.
Relay Count Tracking
The PXI-2576 counts relay closures on each relay. Relay counts are
incremented each time a relay is actuated. You can retrieve the
counts, stored on board the module, programmatically and use them
for predictive maintenance to reduce unexpected system downtime.
