GE Fanuc Daughterboard IC697MEM717 512K PLC Memory

Product Overview

The GE Fanuc IC697MEM717 is a high-performance CMOS expansion memory daughterboard designed specifically for the Series 90-70 PLC family. This module provides critical storage expansion for complex logic programs and extensive application data. 

Technical Configuration

The IC697MEM717 functions as a hardware expansion for Series 90-70 CPUs, featuring a streamlined architecture for system integration:

• Memory Type: High-speed CMOS RAM for volatile program and data storage.
• Maximum Capacity: Supports configurations up to 512K (Kilobytes) to handle dense logic rungs.
• Installation: Plug-in daughterboard design that mounts directly onto the main CPU module.
• Data Retention: Features 6 months of nominal memory retention when supported by the system battery.
• Voltage Logic: Optimized for standard 5V DC operation via the CPU interface.

Technical Specifications

Installation & Maintenance

Installation of the IC697MEM717 requires the system power to be completely off to prevent CMOS damage. Carefully align the daughterboard pins with the CPU connectors and secure them firmly. Since this is volatile memory, verify the PLC battery health before any scheduled power-down; the nominal 6-month retention period relies entirely on a functional battery. During maintenance, utilize anti-static wrist straps to prevent ESD damage to the sensitive CMOS components.

Engineering Advantages

The IC697MEM717 allows for significant scalability within the Series 90-70 framework without requiring a full CPU upgrade. Its CMOS technology provides the low-latency response times needed for high-speed industrial processes. By expanding the available register and program space, engineers can optimize CPU scan times and improve overall system throughput in high-density I/O configurations.

Technical FAQs

Q1: Does this module require software configuration to recognize the added memory?
A1: Yes. After physical installation, you must update the hardware configuration in your programming software (Logicmaster or Proficy) to reflect the new memory size.

Q2: Can I hot-swap the IC697MEM717 while the PLC is running?
A2: No. Attempting to install or remove the daughterboard while the system is energized will likely result in permanent hardware failure and total data loss.

Q3: Is this module compatible with Series 90-30 PLCs?
A3: No. The IC697MEM717 is designed exclusively for the mechanical and electrical interface of the Series 90-70 CPU modules.
