GE IC697CPX928 Series 90-70 CPU 96MHz 6MB RAM 12K I/O Module

Product Overview

The GE IC697CPX928 is a high-capacity, high-speed Central Processing Unit (CPU) designed for the Series 90-70 Programmable Logic Controller (PLC) family. This module is powered by a 96 MHz 80486DX4 microprocessor, specifically engineered to handle large-scale automation tasks with significant memory requirements. With a robust unit weight of 0.85 kg, it offers industry-leading processing speed and a massive 6MB memory footprint for complex industrial applications.

Advanced Computational Power

Rapid Logic and Math Execution

The IC697CPX928 is optimized for high-performance logic, capable of performing Boolean functions in just 0.4 microseconds. Beyond standard logic, it natively supports floating-point calculations, making it suitable for advanced motion control and process-heavy algorithms that require mathematical precision and low latency.

Expansive Memory & Data Retention

This CPU features an impressive 6MB of user and program data memory, allowing for extensive code storage and data logging. To ensure data integrity, it utilizes a Lithium CMOS battery for memory retention. Additionally, it supports up to 256KB of optional flash memory (NVRAM) and keeps its firmware stored in flash memory for easy updates and permanent storage.

Technical Specifications

System Integration & Requirements

Occupying a single slot in the Series 90-70 rack, the IC697CPX928 maximizes backplane efficiency. It provides three integrated serial ports supporting both RS-232 and RS-485 standards, facilitating easy connection to local HMIs and factory-wide networks. For installations where ambient temperatures exceed 50°C (122°F), the use of a 70 CFM cooling fan is required to maintain optimal processing stability and hardware longevity.

Industrial Connectivity

The 12K total I/O point capacity allows for a versatile mix of digital and analog modules, ensuring the IC697CPX928 can scale to meet the needs of diverse industries such as power generation, pharmaceutical manufacturing, and large-scale water treatment. Its ability to manage high-density I/O configurations while maintaining rapid scan times makes it a top-tier choice for sophisticated control architectures.

Technical FAQs

Q1: What distinguishes the CPX928 from the CPX935 model?
A1: While both share a 96MHz speed, the CPX928 offers a significantly larger 6MB memory capacity compared to the 1MB found in the CPX935, making it better suited for data-intensive applications.

Q2: How is the firmware updated on this module?
A2: The firmware is stored in flash memory, which can typically be updated via the serial ports using GE Fanuc programming tools without the need for hardware replacement.

Q3: Does the 0.85 kg weight include the CMOS battery?
A3: Yes, this is the net weight of the module with standard onboard components. We recommend replacing the Lithium battery periodically to prevent data loss during power outages.
