GE IC697CPX928-CD

Product Introduction

GE IC697CPX928-CD is a high-performance CPU module engineered exclusively for GE’s 90-70 Series PLC systems, serving as the “control brain” for complex industrial automation applications that demand fast processing, extensive I/O support, and versatile communication. Unlike entry-level 90-70 CPUs (e.g., GE IC697CPU731), GE IC697CPX928-CD delivers enhanced processing power (80 MHz RISC processor), expanded memory (1 MB SRAM/2 MB Flash), and multi-interface connectivity—making it ideal for tasks like multi-loop PID control, large-scale data logging, and integration with enterprise-level SCADA systems.

As a flagship control component of the 90-70 ecosystem, GE IC697CPX928-CD plays a pivotal role in ensuring operational efficiency and reliability: its 0.2 μs basic instruction speed enables real-time response to dynamic process changes (e.g., adjusting chemical dosing in refineries), while its support for 4096 I/O points accommodates sprawling systems (e.g., automotive assembly lines with dozens of stations). For example, in a large-scale food processing plant, GE IC697CPX928-CD controls 12 PID loops (for temperature/flow regulation), logs 50,000 daily production events, and transmits data to a central MES via Ethernet—all while coordinating with GE IC697CMM712 communication modules and GE IC697VAL134 analog modules.

Core Advantages and Technical Highlights

80 MHz Processor for Ultra-Fast Control: GE IC697CPX928-CD’s 80 MHz RISC processor executes basic instructions in 0.2 μs—4x faster than GE IC697CPU731 (0.8 μs). This speed is critical for high-throughput processes like pharmaceutical batch manufacturing, where 100+ variables (temperature, pressure, mixing speed) must be monitored and adjusted in real time. A biotech plant using GE IC697CPX928-CD reduced batch cycle time by 15% (from 4 hours to 3.4 hours) by eliminating processing delays, increasing annual production capacity by 200,000 units.

Expandable Memory for Large-Scale Applications: With 1 MB SRAM and 2 MB Flash (expandable to 8 MB via GE IC697MEM733), GE IC697CPX928-CD stores complex programs (e.g., 500+ logic rungs for multi-station control) and long-term data logs. A municipal wastewater treatment plant expanded the module’s memory to 4 MB, enabling 6 months of hourly data logging (pH, turbidity, chemical usage) for regulatory compliance. This eliminated the need for external data loggers, saving $8,000 annually in hardware and maintenance costs.

Multi-Interface Connectivity for Seamless Integration: Equipped with 2× Ethernet ports, 1× RS-485 port, and 1× Genius Bus port, GE IC697CPX928-CD connects to diverse industrial systems. A automotive parts supplier uses one Ethernet port for Modbus TCP/IP communication with a SCADA system, the second for SNP communication with GE HMIs, and the Genius Bus port for distributed I/O (e.g., GE IC697BEM731 modules). This multi-protocol support avoided costly protocol converters, reducing system costs by $3,500 per installation.

Built-In PID and Multi-Tasking for Complex Control: GE IC697CPX928-CD includes 128 built-in PID blocks and supports 8 concurrent tasks—eliminating the need for specialty control modules. A chemical refinery using the module to control 24 distillation towers runs 8 tasks simultaneously (4 for PID control, 2 for data logging, 2 for alarm management). The built-in PID blocks maintained process stability within ±0.1% of setpoints, reducing product waste by 25% compared to systems relying on external PID controllers.

High MTBF for Mission-Critical Reliability: With a MTBF of 600,000 hours (40°C ambient), GE IC697CPX928-CD outperforms most industrial CPUs (average MTBF: 300,000 hours). A nuclear power plant’s auxiliary control system has operated GE IC697CPX928-CD for 7 years without failure, ensuring continuous monitoring of coolant flow and pressure—critical for preventing equipment overheating and maintaining plant safety.

Typical Application Scenarios

GE IC697CPX928-CD excels in complex, mission-critical automation applications across industries, with three high-impact use cases:

In oil & gas refining (100,000 barrels per day), GE IC697CPX928-CD controls a 90-70 system with 16× GE IC697VAL134 analog modules (monitoring reactor temperatures/pressures) and 8× GE IC697CMM712 communication modules (transmitting data to a plant-wide SCADA). Its 80 MHz processor adjusts 24 PID loops (for fuel/air ratio control) in 0.5 ms, ensuring optimal combustion efficiency and reducing CO2 emissions by 8% annually. The module’s Genius Bus port connects to 12 distributed I/O racks (via GE IC697BEM731), cutting wiring costs by 40% compared to a centralized I/O setup.

In automotive assembly (multi-model production), GE IC697CPX928-CD manages 8 assembly stations, each with 32 I/O points (proximity sensors, robotic grippers). Its 4096 I/O capacity supports 256 total I/O points, while multi-tasking runs 6 concurrent tasks (station control, quality checks, recipe management). When switching between car models (e.g., sedan to SUV), the module loads new recipes in <1 second—no downtime required. A Detroit-based plant using GE IC697CPX928-CD increased production flexibility, enabling 4 model changes per shift (up from 2 with older CPUs).

In pharmaceutical sterile manufacturing, GE IC697CPX928-CD controls 12 PID loops (for temperature, pressure, and airflow in cleanrooms) and logs 100,000+ batch data points daily. Its expandable memory (6 MB) stores 1 year of batch records for FDA 21 CFR Part 11 compliance, while Ethernet connectivity transmits real-time data to a validation server. The module’s ESD protection (±15kV) withstands electrostatic discharges common in cleanroom environments, preventing CPU resets that would invalidate batches. Over 3 years, the plant avoided 12 costly batch rejections (each costing $50,000) due to the module’s reliability.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing GE IC697CPX928-CD, confirm compatibility with the 90-70 chassis (e.g., GE IC697CHS020) and power supply (GE IC697PWR710H). Ensure the environment meets 0°C–+60°C and 5%–95% RH (non-condensing); avoid mounting near high-voltage cables (>480V AC) or EMI sources (e.g., arc welders). Required tools: Torque screwdriver (0.6–1.0 N·m), ESD-safe gloves, multimeter, and Proficy Machine Edition v10.0+. Safety precautions: Disconnect chassis power; apply lockout/tagout to prevent electrical shock; handle the module by edges to avoid ESD damage.

Slide GE IC697CPX928-CD into 90-70 Chassis Slot 1 until it engages the backplane, then secure with chassis screws (torque to 0.8 N·m). Connect communication cables: Ethernet (CAT5e/CAT6) to SCADA/HMI, RS-485 to Modbus devices, and Genius Bus to distributed I/O. Power on the chassis; verify LEDs: green (power/run), no red (fault). Use Proficy Machine Edition to upload the control program, configure PID loops (setpoint, gain, integral time), and enable data logging. Test CPU responsiveness by simulating a sensor input change (e.g., increasing temperature) and confirming PID output adjustment within 0.5 ms.

Maintenance suggestions: For daily use, monitor GE IC697CPX928-CD’s LEDs—red LED indicates a fault (check Proficy for error codes: e.g., “program corruption,” “low battery”); amber LED signals warnings (replace backup battery if lit). Every 6 months, clean the module with compressed air (remove dust from vents) and retighten communication cables. Annually, back up the program to a PC, test the watchdog timer (simulate a program freeze to confirm reset), and replace the backup battery (GE part #IC697BAT001) to maintain SRAM data retention. If a hardware fault occurs, replace with a GE-approved GE IC697CPX928-CD spare—third-party CPUs may not support 90-70 backplane timing or PID features.
