The X-MAX-1 module is fitted with a 486
CPU with 8 KByte cache. The
clock frequency of the local CPU is currently
between 33 MHz and 100 MHz
(internal), depending on the version.
The X-MAX-1 module is already fitted with
extensive peripheral facilities. In addition to
the Flash EPROM and RAM (of up to 16
Mbyte each) it has 4 timers, interrupt
and DMA controller, a serial RS-232 interface
with all modem control lines and a
printer interface, a clock, a watchdog and
voltage monitor. The clock can be buffered
by an external battery. All interfaces are PC
compatible.
The Flash EPROM on the X-MAX-1 module
contains the OsX real-time multi-tasking
operating system for up to 1024 tasks.
Real-time programs for tasks such as
measured data acquisition, control, PID
controllers, function generators or FFTs are
included with the module. Complete PLC
protocols such as Siemens 3964/R, GE
Fanuc and PROFIBUS are also available for
serial communication.
Further CPU modules with even more
powerful processors are under development, for instance with a
strong ARM CPU. These CPU modules can be
mixed in any combination on a MAX6pci
carrier card. The carrier card can also be
used in what is called "stand-alone" mode.
In this case the application programs are in
the Flash ROM of one of the modules, e.g.
an X-MAX-1. Communication with the host
computer then takes place via, for instance,
a serial interface (RS-232, RS-485 etc.) or ethernet.
It is also possible to write your own real-time
programs for the card, working in the
familiar PC development environment.
