GE IC698CRE040-HN

Product Overview: The GE IC698CRE040-HN is a high-availability Redundant CPU (CRE) in the PACSystems RX7i platform, intended for hot-standby (redundant) configurations. It is based on a 1.8 GHz Pentium M processor with 64 MB RAM and 64 MB flash memory, providing seamless switchover to a backup CPU in case of a fault, which is critical for continuous processes. The “-HN” suffix indicates a specific regional or hardware revision variant. This CPU is used where high reliability and minimal downtime are mandatory.

Description

GE IC698CRE040-HN

Technical Specifications:

  • Processor: 1.8 GHz Intel Pentium M
  • Memory: 64 MB battery-backed RAM; 64 MB non-volatile Flash
  • Ethernet Ports: Two embedded 10/100 Mbps RJ45 ports supporting SRTP and Modbus TCP
  • Serial Ports: Three isolated serial ports (RS-232/RS-485) for SNP, Modbus RTU slave, and serial I/O
  • Redundancy Support: Hot-standby with synchronization via Redundancy Memory modules
  • ECC (Error Checking and Correction): Enabled by default for redundant CPUs
  • Operating Temperature: 0 °C to 60 °C
  • Voltage: 5 VDC backplane supply

Functional Features:

  • Hot-standby CPU switchover within one scan for maximum uptime
  • ECC protects memory integrity; single-bit errors are corrected
  • Supports both SRTP and Modbus TCP client/server roles
  • Bit/Word addressing, auto symbol variable location, and test edit mode
  • Embedded web server for data monitoring and maintenance access

Application Scenarios:

  • Power generation and distribution systems
  • Oil and gas platforms and refineries
  • Critical process control (chemical, pharmaceutical)
  • Large-scale manufacturing where unplanned downtime is unacceptable

Performance Parameters:

  • Fast scan rates for both control and redundancy tasks
  • High-speed deterministic data exchange between primary and secondary CPUs
  • Large I/O capacity compatible with RX7i I/O modules

Material and Structural Characteristics:

  • Industrial-grade module with robust connectors and optional conformal coating
  • Designed for RX7i universal backplane mounting
  • Front panel LEDs for CPU, Ethernet, and redundancy status

Working Principle: The primary CPU runs the control program and synchronizes data with the standby CPU via redundancy memory. If a fault is detected, the standby CPU takes over within one scan cycle, maintaining process continuity with minimal disruption. Installation Requirements:

  • Install in an RX7i rack with matching Redundancy Memory modules
  • Use proper grounding and cooling arrangements
  • Configure redundancy settings in Proficy Machine Edition and verify cabling between CPUs

Usage Notes:

  • ECC must be enabled when using redundant CPUs; see GFK-2308 for details
  • Periodically verify redundancy synchronization status
  • Ensure firmware compatibility between paired CPUs and redundancy modules
  • Follow lockout/tagout procedures during maintenance
