PACSystems RX3i Manual

GFK-2316
August 2004
The RX3i CPU is programmed and configured by the
programming software to perform real time control of
machines, processes, and material handling systems. The
CPU It communicates with the programmer and HMI
devices via a serial port using SNP Slave protocol. It
communicates with I/O and smart option modules over a
dual backplane bus that provides both:
■
High-speed, PCI backplane for fast throughput of new
advanced I/O.
■
Serial backplane for easy migration of existing Series
90-30 I/O
Features
■
Contains 10 Mbytes of battery-backed user memory
and 10 Mbytes of non-volatile flash user memory.
■
Provides access to bulk memory via reference table
%W. The upper limit of this memory area can be
configured to the maximum available user RAM.
■
Configurable data and program memory.
■
Programming in Ladder Diagram, Structured Text,
and C.
■
Supports auto-located Symbolic Variables that can
use any amount of user memory.
■
Reference table sizes include 32Kbits for discrete %I
and %Q and up to 32Kwords each for analog %AI
and %AQ.
■
Supports most Series 90-30 modules and expansion
racks. For a list of supported I/O, Communications,
Motion, and Intelligent modules, see the PACSystems
RX3i Hardware and Installation Manual, GFK-2314.
■
Supports up to 512 program blocks. Maximum size for
a block is 128KB.
■
Test Edit mode allows you to easily test modifications
to a running program.
■
Bit-in-word referencing allows you to specify individual
bits in a WORD reference in retentive memory as
inputs and outputs of Boolean expressions, function
blocks, and calls that accept bit parameters.
■
Battery-backed calendar clock.
■
In-system upgradeable firmware.
PACSystems™ RX3i
Central Processing Unit
■
Two serial ports: an RS-485 serial port and an
RS-232 serial port.
■
Supports Ethernet communications via the rack-
based Ethernet Interface module (IC695ETM001):
−
Data exchange using Ethernet Global Data
(EGD)
−
TCP/IP communication services using SRTP
− Comprehensive station management and
diagnostic tools
−
Two full-duplex 10BaseT/100BaseT/TX (RJ-45
Connector) ports with an internal network switch
providing auto-negotiated network speed, duplex
mode, and crossover detection
