Product Overview

The IC697CPM924 belongs to the Series 90-70 product line. Its product type is a CPU Module. The product classification is Controllers & CPUs. The current price for this item is ¥6,850 RMB, and the product gross weight is 0.85 kg.

GE Fanuc designed this CPU module specifically for use with Series 90-70 PLCs . The IC697CPM924 is a 32-bit CPU with a microprocessor clocked at 64 megahertz . In addition to fixed point operation, this CPU also supports floating point operations . The module provides 1 megabyte of RAM for program and data storage. Therefore, this CPU suits medium to large control applications requiring mathematical processing.

Technical Specifications

Processor and Memory

The IC697CPM924 operates with a 64 megahertz clock speed. The 32-bit architecture provides efficient data handling. Floating point operations are supported, enabling complex mathematical calculations. Total RAM available is 1 megabyte for user programs and data storage. Consequently, this CPU handles demanding control algorithms effectively.

Battery Backup

A replaceable lithium battery provides backup power to the RAM during mains power failures. The rated shelf life of the lithium battery is 10 years at 68°F (20°C) ambient temperature. When PLC rack power is removed, the battery maintains RAM contents for a nominal period of 6 months . The old battery must be removed before installing a new one. Therefore, schedule regular battery replacement to prevent data loss.

Operating Temperature

The operating temperature range spans 0 to 60 degrees Celsius . Exceeding this range may degrade performance. Extreme high temperatures can even lead to module failure. For reliable operation, install the IC697CPM924 in a temperature-controlled environment. Ensure adequate airflow around the module.

Clock Accuracy

The time-of-day clock accuracy reaches 3.5 seconds per day maximum . The elapsed time clock accuracy measures 0.1% maximum . These specifications suit most industrial scheduling and time-stamping applications. For higher precision timing, consider external time synchronization.

Configuration and Communication

The IC697CPM924 supports software configuration through multiple interfaces. An integrated serial port provides direct programming access. A parallel port on the bus transmitter PLC module offers additional connectivity. An optional Ethernet module can connect to computers running configuration software. Therefore, users have flexible options for programming and monitoring.

Run/Stop Switch

A 3-position RUN/STOP switch controls module operation locally. Users can also control operation remotely from programming computers. This switch provides a physical means to change operating modes. Use the switch during debugging and maintenance activities.

Installation Requirements

Power should be removed from the PLC rack prior to module installation. This prevents electrical damage to both the module and the backplane. Always follow proper electrostatic discharge (ESD) precautions when handling the IC697CPM924 .

Installation Guide

Follow these steps to install your IC697CPM924 correctly.

1. Power Down the Rack: Disconnect power from the Series 90-70 rack completely. This prevents electrical damage during installation.

2. Select a Slot: Choose an appropriate slot in the Series 90-70 rack. Refer to your system manual for CPU slot requirements.

3. Insert the Module: Align the IC697CPM924 with the slot guides. Push firmly until the module seats into the backplane connector.

4. Secure the Module: Tighten the retaining screws at the top and bottom. This secures the CPU module in place.

5. Connect Programming Cable: Attach your programming computer to the integrated serial port. Alternatively, connect via Ethernet if an optional module is installed.

6. Apply Power: Restore power to the Series 90-70 rack. Verify that the IC697CPM924 powers up without errors.

7. Configure the Module: Use configuration software to set up the CPU parameters. Set the RUN/STOP switch to the desired position.

8. Download User Program: Transfer your control program to the 1MB RAM . Verify successful download and program execution.

9. Test Operation: Run diagnostic checks to confirm all functions work properly. Monitor the time-of-day clock accuracy if needed.

Frequently Asked Questions (FAQ)

1. Does the IC697CPM924 support floating point math operations?
Yes, unlike some older GE Fanuc CPUs, the IC697CPM924 supports both fixed point and floating point operations . This capability enables complex mathematical calculations in your control programs.

2. How long does the battery backup last when rack power is off?
The lithium battery provides 6 months of backup power to maintain RAM contents. After this period, data may be lost. Replace the battery regularly to ensure data retention.

3. What is the battery shelf life before installation?
The rated shelf life is 10 years at 68°F (20°C) ambient temperature. Store spare batteries in a cool, dry environment to maximize shelf life.

4. What is the operating temperature range for this CPU?
The IC697CPM924 operates reliably between 0 and 60 degrees Celsius . Exceeding this range may cause performance degradation or module failure. Install in a temperature-controlled environment.

5. How do I control the CPU operating mode?
Use the 3-position RUN/STOP switch on the module front panel for local control. Alternatively, control the mode remotely from programming computers via serial or Ethernet connection.
