IC695CRU320-CD/EH RX3i redundant CPU

Description

IC695CRU320-CD/EH
The PACSystems* RX3i Redundancy CPU can be used to
perform real time control of machines, processes, and
material handling systems. The CPU 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:
▪ 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
▪ Hot standby (HSB) redundancy. Two redundant units
make up a redundancy system. Each unit requires one
Redundancy CPU (IC695CRU320) and a redundancy
Memory Xchange module (IC695RMX128/228) configured
as a redundancy link.
▪ Contains 64 Mbytes of battery-backed user memory and
64 Mbytes of non-volatile flash user memory.
▪ Provides access to bulk memory via reference table %W.
▪ Configurable data and program memory.
▪ Programming in Ladder Diagram, Structured Text,
Function Block Diagram, and C. Refer to PACSystems RX7i
& RX3i CPU Programmer’s Reference Manual, GFK-2950.
▪ 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 32K words 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, refer to the PACSystems
RX3i System Manual, GFK-2314F or later.
▪ Supports up to 512 program blocks. Maximum size for a
block is 128KB.
▪ CPU firmware may be upgraded in the field.
▪ CPU supports firmware upgrades of modules in its
backplane.
▪ Two serial ports: an RS-485 serial port and an RS-232
serial port.
