GE Fanuc IC697MEM715 Memory Module PLC Expansion

Product Introduction

The IC697MEM715 memory module is a versatile expansion solution for GE Fanuc Series 90-70 programmable logic controllers. This CMOS-based unit extends both logic memory and data storage capacity for 771/772 CPUs and programmable co-processor modules. It comes in multiple capacity options, including 64 KB, 128 KB, 256 KB, and 512 KB. One of its key advantages is the daughterboard design, which allows it to share the same slot as the base module without requiring an extra rack position. The built-in lithium battery provides up to 10 years of shelf life and retains user memory for six months without external power. Additionally, the module includes automatic checksum error checking during power cycles and resets, ensuring reliable operation in demanding industrial environments.

Technical Specifications

The IC697MEM715 offers a flexible memory architecture that suits a wide range of automation tasks. It supports both program storage and data storage, and you can configure it to prioritize either function based on your application needs. The module uses CMOS technology, which consumes very little power and enhances reliability.

The checksum routine continuously verifies the logic program memory for errors. Therefore, the system maintains high data integrity. Meanwhile, the module automatically checks storage memory during soft resets, hard resets, and power cycles. This built-in diagnostic feature minimizes unexpected downtime.

Mechanical and Environmental Parameters

The IC697MEM715 is built to operate reliably in standard industrial control room conditions. Its compact design requires no additional slot, making it an efficient choice for crowded racks.

Operating Temperature: 20°C (68°F) nominal; suitable for typical plant environments
Storage Temperature: –40°C to +85°C
Relative Humidity: 5% to 95% (non-condensing)
Vibration Resistance: 1 G peak, 10–150 Hz
Shock Resistance: 15 G peak, 11 ms duration
Dimensions: Approximately 3.5 cm x 10.0 cm x 12.0 cm (height x width x depth)
Weight: 0.45 kg

Furthermore, the module draws minimal current from the backplane, so it does not overload the power supply. Its lithium battery maintains the calendar clock and user memory even if the main power fails, ensuring your program and data remain safe for up to six months.

Installation Guide

Installing the IC697MEM715 is straightforward and requires no special tools. First, ensure the PLC system is powered off and disconnected from the main supply. Next, locate the base module that will host the daughterboard. The IC697MEM715 fits directly onto the base module's designated connector, sharing the same slot. There is no need to reserve an extra rack position, which simplifies cabinet layout.

After securing the module, connect the lithium battery if it is not pre-installed. Then, power on the system and verify that the module is recognized by the CPU. Use the MS-DOS-based configuration software to set the memory size and allocate storage between data and program areas. Finally, perform a soft reset to trigger the automatic checksum verification. If the PMC error check passes, the module is ready for normal operation. For best results, keep the ambient temperature near 20°C and ensure adequate airflow around the rack.

Frequently Asked Questions (FAQ)

1. What capacities are available for the IC697MEM715?
   The IC697MEM715 comes in four memory sizes: 64 KB, 128 KB, 256 KB, and 512 KB. Please specify your required capacity when placing an order.

2. Does this module require an extra slot in the PLC rack?
   No, the IC697MEM715 operates as a daughterboard and shares the same slot as the base module. Therefore, it does not consume any additional rack space.

3. How long can the module retain data without power?
   The built-in lithium battery preserves user memory for up to six months without applied power. The battery itself has a shelf life of up to 10 years.

4. Which CPUs are compatible with this memory module?
   This module works with GE Fanuc Series 90-70 771/772 CPUs and programmable co-processor modules. It expands both logic and data memory for these processors.

5. What software do I need to configure the IC697MEM715?
   Configuration requires MS-DOS-based software running on a Windows PC. The module does not support newer Windows-native tools, so please ensure you have the correct legacy software environment.
