IC697MEM731 GE Fanuc Memory Module

IC697MEM731 GE Fanuc Expansion Memory Module

Product Introduction

The IC697MEM731 memory module belongs to the GE Fanuc Series 90-70 product line. This 32-bit CMOS board provides either 128 KB or 256 KB of nonvolatile flash memory. Engineers use it to expand logic and data storage on compatible CPUs. The module works with CPU models 771, 772, 780, 781, 782, 788, and 789.

Additionally, the IC697MEM731 relies on the CPU’s battery for memory retention. It keeps all data safe for up to six months without external power. This feature prevents program loss during unexpected shutdowns. The module also supports error checking through the CPU’s checksum routine.

Installation Guidelines

Installing the IC697MEM731 is straightforward but requires care. First, power down the Series 90-70 system completely. Then locate the CPU where you will mount the module. Align the expansion memory board properly with the connectors on the CPU.

Next, fasten the screws so they align with the standoffs already installed on the CPU. Use a Philips screwdriver to secure the module firmly. For instance, ensure no gaps remain between the board and the standoffs. Finally, power up the system and verify that the CPU recognizes the new memory.

Only qualified personnel should handle the IC697MEM731. Always follow the programmable controller installation instructions from the manual. The module checks each byte of the SRAM continuously. Memory parity errors are reported to the CPU as background tasks.

Frequently Asked Questions (FAQ)

1. Which CPUs work with the IC697MEM731?
It works with GE Series 90-70 CPUs including the 771, 772, 780, 781, 782, 788, 789, and PCM.

2. Does the IC697MEM731 need its own battery?
No. It uses the battery on the CPU for memory retention during power loss.

3. How long can the IC697MEM731 retain data without power?
It retains data for six months nominally without applied power.

4. Does this module require an extra backplane slot?
No. It mounts directly on the CPU as a daughterboard, so no additional slot is needed.

5. How does the IC697MEM731 handle error checking?
The CPU runs a checksum routine continuously. Parity errors are reported to the CPU immediately.
