Description Reviews

The GE Fanuc IC697MEM717, also cataloged as the IC697MEM717 CMOS Expansion RAM Module, operates as a dedicated hardware component for memory expansion within Series 90-70 systems. The module integrates directly with compatible CPU and PCM host systems through a dedicated expansion bus, providing configurable solid-state data and program storage without consuming additional rack slot space.

Backplane Bus Communication Velocity & I/O Density Scaling

The IC697MEM717 interfaces via a direct expansion bus connection to bypass standard backplane bus communication velocity constraints, maintaining high-speed CMOS access times below 200 nanoseconds. This direct interface ensures that the host CPU (such as the CPU 771 or CPU 772) can scale its registers, local variables, and memory-intensive I/O density configurations without experiencing communication bus bottlenecks. To secure the expanded data space, the memory utilizes the host module's battery-backed structure and executes continuous CPU checksum routines to verify memory block integrity during active cycles.

Frequently Asked Questions

Q: Does the installation of the IC697MEM717 require a separate slot in the Series 90-70 rack?

A: No. The IC697MEM717 is designed as a direct-attach daughterboard expansion module that mounts directly onto the host CPU or PCM board, leaving all physical chassis slots free for I/O modules.

Q: How is data preserved on this memory module during a total power failure?

A: Data retention is maintained by the battery-backup circuitry located on the host CPU or PCM module. The expansion RAM relies on this host power source to keep its CMOS cells energized.

Q: Is this memory expansion hot-swappable?

A: No. Because the IC697MEM717 plugs directly into the host CPU or PCM motherboard circuitry, the rack power must be completely shut off and the host module removed from the backplane before installation or removal of the expansion card.

Field Installation Guidelines

Static Discharge Precautions: Always wear an electrostatic discharge (ESD) wrist strap grounded to the chassis before handling the IC697MEM717 to avoid damaging the CMOS components.
Mating Connection Alignment: Align the expansion pins on the IC697MEM717 carefully with the socket connectors on the host CPU 771, CPU 772, or PCM board. Press down evenly until the module is fully seated.
Firmware/Software Configuration: After physical installation, configure the memory size parameters (ranging from 64 KB to 256 KB) within the system programming software to match your specific application requirements.
Testing Routine Verification: Perform a complete CPU checksum diagnostic test upon initial power-up to confirm the host processor successfully addresses and verifies the entire expanded memory block.
