Product Description

Product Parameters

Advantages and Features

1. Ultra-Fast Processing Speed: With a 150 MHz 32-bit RISC processor, the GE IC697CPX928-HF executes complex control logic, sequential function charts, and motion control algorithms up to 40% faster than standard Series 90-70 CPU modules, reducing latency in time-sensitive applications like robotic assembly and precision process control.
2. Expanded Memory & Data Retention: 8 MB RAM and 4 MB non-volatile flash memory provide ample space for large application programs, long-term data logging, and firmware updates, eliminating the need for external memory modules even in data-intensive industrial setups.
3. Enhanced Fault Tolerance: Equipped with a watchdog timer, ECC memory, and real-time diagnostic tools, the GE IC697CPX928-HF detects and mitigates errors before they cause system downtime, ensuring reliable operation in mission-critical environments like power plants and chemical refineries.
4. Full Legacy Hardware Compatibility: Seamlessly integrates with all existing Series 90-70 modules and control head stations, allowing users to preserve hardware investments while upgrading to a more powerful CPU, reducing total cost of ownership.
5. High I/O Scalability: Supports double the I/O capacity of standard Series 90-70 CPUs (16384 digital/2048 analog points), making it suitable for large-scale industrial complexes and future system expansions without core hardware replacement.
6. Simplified Maintenance & Troubleshooting: Built-in diagnostic LED indicators and compatibility with GE’s VersaPro/CIMPLICITY software enable remote monitoring, error identification, and program updates, minimizing on-site maintenance time and costs.

Application Cases in Application Fields

Selection Suggestions and Precautions

1. Selection Suggestions:
   • Choose the GE IC697CPX928-HF for Series 90-70 PLC systems in mission-critical applications (power generation, nuclear safety, petrochemicals) where fault tolerance and fast processing are non-negotiable.
   • Opt for this module if you need to scale up I/O capacity for large-scale industrial setups, such as EV battery plants, refineries, or water treatment facilities, without replacing existing control head stations.
   • Prioritize the GE IC697CPX928-HF for legacy system upgrades, as its full compatibility preserves hardware investments and minimizes operational downtime during deployment.
2. Precautions:
   • Ensure the module is installed in a genuine GE Series 90-70 rack and paired with compatible control head stations to avoid backplane communication errors or performance degradation.
   • Verify that the Series 90-70 backplane provides stable 5 VDC power, as voltage fluctuations can damage the CPU’s internal components and corrupt stored programs.
   • Avoid operating the module outside the 0°C to 60°C temperature range; install it in a well-ventilated, dust-free control cabinet to prevent overheating during high-load operations.
   • Regularly back up the non-volatile flash memory via GE’s programming software to prevent data loss in case of module failure or accidental configuration changes.
   • Use only GE-approved I/O and communication modules with the GE IC697CPX928-HF to maintain system stability and avoid voiding the product warranty.
