SR9000 Smart Star System |
|
The Smart Star is a modular and expandable embedded control system designed for demanding real-time
control and data acquisition applications. Multiple I/O card options--including digital, A/D,
D/A, and relays--allow users to closely match their specific I/O needs. The Smart Star CPU card
comes in both Ethernet and non-Ethernet versions, and a cost-effective keypad/display is also
available.
- Ethernet connectivity—CPU card with or without Ethernet
- Flexible functionality—modular configuration to easily interchange or replace
individual I/O cards
- Multiple I/O card options—digital I/O, A/D, D/A, relay
- Expandable—up to 168 I/O
- Cost-effective—low cost per I/O
- Optional keyboard/display—backlit 122 x 32 pixel graphic LCD with 7 user-relegendable
keys, 7 LEDs
To make integration easy, the Smart Star has been designed from
the ground up, with careful consideration given to configuration,
implementation, and maintenance requirements. Modular expansion
allows you to use the same Smart Star architecture in both small
or large applications and where cost and physical size are critical.
Unprecedented I/O density is provided with up to 168 I/O supported
in a panel size less than 27.3 square inches.
The basic Smart Star system consists of a rugged backplane with
power supply, a CPU card, and one or more I/O cards of your choice.
The Smart Star backplane is available in two models, the 8-slot
SR9010 and the 4-slot SR9050. With one slot on the backplane reserved
for the CPU, remaining slots can be utilized for any combination
of I/O cards, giving designers a customizable platform for their
applications. The CPU card is powered by the Rabbit 2000™ microprocessor
operating at 22.1 MHz and features 512K of Flash memory and up to
512K of SRAM for program and data storage.
Connections to I/O cards are via pre-assembled flat ribbon-cable
assembly or optional field wiring terminals (FWTs). Ribbon-cable
provides the lowest cost connection for high-volume applications
with no variation in wiring from unit to unit. FWTs provide pluggable
or screw-type terminals for discrete, customized connections and
easy field maintenance.
Programming the Smart Star
Programs are developed using Rabbit's industry-proven Dynamic C®
software development system. An extensive library of drivers and sample programs is provided,
along with royalty-free TCP/IP stack with source. The Smart Star can be programmed and debugged
over Ethernet/Internet using appropriate accessory hardware. For optional keypad/display, software
libraries and a built-in converter program facilitate display of international characters, bitmap
images, and graphic constructs such as circles, lines, and squares.
