IC695CRU320-CA New RX3i 1Ghz Redundancy CPU With Two Serial Ports

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.

IC695CRU320

Product parameter

IC695CPU320/CRU320 Models
■ IC695CPU320: 1 GHz CPU microprocessor
■ IC695CRU320: 1 GHz CPU microprocessor with redundancy
Serial Ports
The CPU has two independent, on-board serial ports, accessed by connectors on the front of the module. Ports 1 and 2 provide serial interfaces to external devices. Either port can be used for firmware upgrades. For serial port pin assignments and details on serial communications, refer to chapter 12.
Indicators
The eight CPU LEDs indicate the operating status of various CPU functions.

Application field

Error Checking and Correction, IC695CRU320
Rx3i Redundancy CPUs provide error checking and correction (ECC), which results in slightly slower system performance, primarily during power-up, because it uses an extra 8 bits that must be initialized.
For details on ECC, refer to the PACSystems Hot Standby CPU Redundancy User’s Guide, GFK-2308.
