XMP
Hardware
Because
computer-based motion control systems vary widely, the XMP has
been designed to accommodate most common industry hardware. This
means providing a variety of platform, porting, form factor, and
voltage options.
Platform
Options
XMP-series
motion controllers are ported to accommodate common industry
software platforms, including:
- Windows95/98
- Windows2000
- WindowsNT
- LynxOS
- VxWorks
- VenturCom
RTSS
- QNX
- PharLap
Form
Factor Options
"Form
factor" refers to the physical shape and size of an XMP controller
and the component(s) it is designed to function with. XMP controllers
are available in the following form factors:
If
your application requires a different form factor, please contact
MEI.
Various
form factors are shown in the figures below. Four types of I/O
connectors are utilized: VHDCI; SERCOS; and, CPCI (rear I/O).

XMP
Interface Options: Networked and XMP-analog
XMP
control systems accommodate two interface categories: networked
and XMP-Analog. The types of hardware associated with each category
are show here:
XMP-analog
- Analog
± 10 VDC
- Pulse
(Step / Dir)
- Quadrature
encoder
- Absolute
encoder
XMP-SERCOS
Systems
SERCOS
(SErial Real-time COmmunication System) is the most common
type of networked motion control. All data is transmitted
over a fiber-optic ring, with each SERCOS device having both
a dedicated input and output. At regular intervals, the XMP
controller receives a coded data packet from each device in
the ring, reporting its current status. The controller then
processes the information, and transmits an updated command
data packet to each SERCOS device. Typical SERCOS cycle rates
vary between 500-1000 samples per second.
XMP-analog
Systems
XMP-analog
controllers represent a traditional form of motion control,
with command and feedback data transmitted via numerous discrete
electrical connections.
