GE Fanuc IC600CB504 / IC600CB507 Series Six Memory Boards
Two Series Six CPU memory-subsystem boards with different functions: internal memory control and 8K register memory.
Product Overview
GE Fanuc IC600CB504 and IC600CB507 are distinct Series Six CPU memory-system boards: IC600CB504 controls internal memory operation and IC600CB507 supplies 8K of register memory.
Both belong to the Series Six CPU memory group and must be coordinated with the installed control-function set.
IC600CB504: Controls the internal memory subsystem.
IC600CB507: Provides 8K of register memory; it is not a substitute for the memory-control board.

Memory Functions
IC600CB504 manages the Series Six internal-memory subsystem rather than supplying user register capacity itself.
IC600CB507 contributes 8K of register memory, making the two catalog numbers complementary functional boards instead of interchangeable revisions.
Register values used by the control program reside in a separate resource from the memory-control function, which is why the two board numbers must be identified independently.
CPU Memory Architecture
The memory-control board coordinates access to CPU memory, while the register-memory board supplies the separate data-register space used by the running application.
Replacing either board requires the exact function and revision to remain aligned with the CPU model and installed memory arrangement.
Board revision and CPU model remain part of the memory architecture because a capacity value alone does not identify the control function supplied by IC600CB504.
IC600CB504 / IC600CB507 FAQ
Is IC600CB507 a larger version of IC600CB504?
No. CB504 is an internal memory control module; CB507 is an 8K register memory module.
Which CPU family lists these boards for IC600CB504 / IC600CB507?
The GE order guide lists them for CPU models 600 or 6000.
Can front-panel similarity establish compatibility for IC600CB504 / IC600CB507?
No. Their functions differ and the full CPU memory configuration must be checked.
What information should be backed up for IC600CB504 / IC600CB507?
Preserve the user program, register-dependent application records and the complete installed board list.
What confirms a successful replacement for IC600CB504 / IC600CB507?
Pass CPU diagnostics, confirm memory/register access and validate the controlled process sequence.
Why must IC600CB504 / IC600CB507 be ordered as separate functions?
One controls memory operation and the other provides register capacity, so the CPU needs the correct functional board rather than a visually similar substitute.
