Fanuc IC697MEM717 PLC Expansion Memory 256 KB New

Product Details

Product Overview

The GE Fanuc IC697MEM717 serves as a high-speed CMOS Expansion RAM module specifically engineered for the Series 90-70 PLC platform. This module expands the volatile memory capacity of CPU 771, CPU 772, or Programmable Coprocessor Modules (PCM). By providing 256 KB of additional storage, it enables the execution of larger control programs and the management of extensive register data sets. The IC697MEM717 mounts directly onto the host processor or PCM module, providing a seamless memory upgrade without consuming an additional slot in the PLC rack. This expansion remains critical for complex automation tasks that exceed the base memory limits of legacy GE Fanuc processors.

Technical Specifications

Engineering Advantages

The IC697MEM717 resolves memory-intensive bottlenecks in aging industrial systems through specialized engineering features:

• Zero-Footprint Installation: The module utilizes a direct-plug design that attaches to the existing CPU or PCM circuit board. This architecture allows for memory expansion in fully populated racks where no free slots remain available for standard expansion cards.

• Low-Latency Data Access: Featuring high-speed CMOS technology with access times under 200 ns, the IC697MEM717 ensures that the CPU maintains its deterministic scan rate. This prevents the "memory lag" often associated with bulk storage expansions, sustaining high-speed logic execution.

• Flexible Logic Allocation: Engineers can configure the 256 KB of expanded space to store either user program logic or register data. This versatility allows the system to accommodate massive PID loop tables or complex recipe management systems required in process control.

• Robust Data Integrity: The host processor monitors the expansion RAM through integrated checksum routines. In the event of a memory parity error or data corruption, the system triggers an immediate diagnostic alarm to prevent the execution of unsafe control logic.

FAQs

• Is this GE IC697MEM717 module 100% Brand New?

  Yes. We supply the IC697MEM717 in 100% Brand New and Original condition. Every module arrives in its original factory-sealed anti-static packaging, ensuring maximum component life and reliability for your Series 90-70 system.

• Does this module require a separate battery for data retention?

  No. The IC697MEM717 utilizes the battery already installed on the host Series 90-70 CPU or PCM module. As long as the host battery remains functional, the expansion RAM will retain all program and register data during power loss.

• Can I use this module with any Series 90-70 CPU?

  The IC697MEM717 is primarily designed for the CPU 771 and CPU 772 models, as well as specific PCM modules. You should verify your CPU's hardware revision and available expansion headers before installation to ensure full electrical compatibility.

• How do I install the expansion RAM?

  Installation requires powering down the PLC rack and removing the host CPU or PCM module. Plug the IC697MEM717 into the designated memory expansion pins on the host board. The CPU automatically recognizes the additional memory upon the next power-up cycle.
