IC697CPX928-CD

Description

Description

The IC697CPX928-CD is a high-performance 32-bit central processing unit (CPU) module developed by GE Fanuc (now part of Emerson’s industrial automation portfolio) for the Series 90-70 Programmable Logic Controller (PLC) system. As the “processing core” of medium-to-large industrial automation systems, it integrates a 96 MHz 80486DX4 microprocessor and advanced memory architecture to deliver fast logic execution and reliable data management—making it ideal for scenarios requiring high I/O capacity and complex calculations, such as manufacturing production lines, process control systems, and energy management networks .

The “-CD” suffix denotes compliance with industrial-grade configuration standards, emphasizing its stability in harsh electrical environments and compatibility with extended temperature ranges. The module features a single-slot design for space efficiency, 6 MB battery-backed RAM for critical data retention, and 256 KB non-volatile flash memory for firmware and program storage. With three built-in serial ports (1×RS-232, 2×RS-485) and support for optional Ethernet modules, it enables seamless integration with HMI, sensors, and third-party devices . Its 0.4 microsecond/boolean instruction scan rate ensures real-time response to dynamic process changes, while compatibility with 12,000 mixed I/O points and 8,000 analog I/O points provides exceptional scalability .

Application Scenarios

A mid-sized automotive component manufacturer in Ohio faced production inefficiencies with its aging PLC system: the existing CPU had a 1.2µs scan rate and limited I/O capacity, causing delays in coordinating 6 robotic assembly stations and 5,000+ I/O points (e.g., proximity sensors, servo drives). Changeovers between 12 product variants required 2–3 hours of manual programming, leading to 15% annual downtime and 2.8% defective parts.

After upgrading to the IC697CPX928-CD, the manufacturer achieved a 67% reduction in scan time (0.4µs/boolean instruction), enabling synchronized control of robotic arms and conveyor systems. The module’s 6 MB RAM supported pre-stored recipe parameters for all 12 product variants, cutting changeover time to 30 minutes. Its dual RS-485 ports simplified daisy-chaining of 20+ barcode scanners, reducing wiring complexity by 50%. Within 6 months, unplanned downtime dropped to 3%, defect rates fell to 0.7%, and annual production output increased by 12%. This scenario highlights how the IC697CPX928-CD solves scalability and speed bottlenecks in high-volume manufacturing .

Technical Principles and Innovative Values

1. High-Speed Processing with Floating-Point Capability

The 96 MHz 80486DX4 processor delivers 0.4µs boolean instruction execution, 3x faster than entry-level Series 90-70 CPUs. Its 32-bit floating-point unit enables precise calculations for process control (e.g., PID tuning for chemical dosing), eliminating rounding errors common in 16-bit systems. A water treatment facility leveraged this to optimize coagulant injection rates, reducing chemical usage by 22% .

2. Software-Centric Configuration for Flexibility

Unlike legacy CPUs with hardware jumpers/DIP switches, the IC697CPX928-CD is fully configured via software (MS-DOS or Windows-based tools like Proficy Machine Edition) over Ethernet or serial ports. This eliminates physical hardware adjustments during system upgrades, cutting reconfiguration time by 80%. A food packaging plant used this feature to remotely update recipe parameters, avoiding 4 hours of monthly downtime .

3. Multi-Protocol Communication for Seamless Integration

Dual RS-485 ports support daisy-chaining of up to 32 devices each (e.g., sensors, drives) via SNP/RTU protocols, while the RS-232 port enables direct programming. Optional Ethernet modules add support for TCP/IP, enabling integration with MES systems. An automotive plant used this to connect the CPU to a cloud-based production dashboard, reducing data latency from 5 minutes to 10 seconds .

4. Rugged Design for Industrial Reliability

The module’s wide operating temperature range and 70 CFM forced air cooling support make it stable in hot factory cabinets. Its battery-backed RAM retains critical data (e.g., production counts, fault logs) during power outages, ensuring seamless restart. A chemical plant reported zero CPU failures over 3 years despite temperature fluctuations from 10°C to 55°C .

Application Cases and Industry Value

1. Chemical Batch Plant (Texas)

The plant’s 8 reaction vessels required precise temperature/pressure control and batch parameter logging. Legacy CPUs struggled with 8,000 analog I/O points, causing 3% batch rejection. Deploying IC697CPX928-CD enabled real-time monitoring of 120 sensors and execution of complex batch logic. Flash memory stored 50+ batch recipes, cutting changeover time by 75%. Rejection rates dropped to 0.5%, saving $400,000 annually .

2. Municipal Power Distribution (California)

A utility company needed to manage 10,000+ I/O points across 20 substations (e.g., voltage sensors, circuit breakers). The IC697CPX928-CD’s RS-485 ports connected to remote I/O racks via Modbus RTU, enabling centralized control. Its fast scan rate reduced fault detection time from 2 seconds to 300ms, minimizing power outages by 40%. The utility avoided $1.2 million in annual downtime costs .
