Hardware
The PCI-7390 is a high performance controller that uses an advanced
dual-processor architecture including a 32-bit CPU combined with a digital
signal processor (DSP) and a custom field programmable gate array
(FPGA). The first-in, first-out (FIFO) bus interface and powerful function
set provide high-speed communications while off-loading complex motion
functions from the host PC for optimum command throughput and system
performance.
The PCI-7390 uses a 100-pin SCSI I/O connector. Each axis of the
PCI-7390 has motion I/O for end-of-travel limit and home switch inputs,
breakpoint (position compare) output, trigger (position capture) input,
inhibit (alarm) input, in-position input, drive (servo) ready input, inhibit
(drive enable) output, shutdown input, alarm clear output and encoder
feedback. The PCI-7390 also has eight non-dedicated user inputs and
eight non-dedicated user outputs.
RTSI
The PCI-7390 supports the National Instruments Real-Time System
Integration (RTSI) bus. The RTSI bus provides high-speed connectivity
between National Instruments products, including image acquisition and
data acquisition products. Using the RTSI bus, you can easily synchronize
several functions to a common trigger or timing event across multiple
motion, image or data acquisition devices.
