GE Fanuc IC600CB524 / IC600CB525 Series Six Plus Control Boards
Two cooperating but non-interchangeable CPU boards: arithmetic control and advanced logic control.
Product Overview
GE Fanuc IC600CB524 and IC600CB525 are paired Series Six Plus processing boards, with IC600CB524 performing arithmetic control and IC600CB525 providing advanced logic control.
These boards operate as parts of a configured Series Six Plus CPU. The logic board connects to the arithmetic board with a ribbon cable and both must match the installed function set.
IC600CB524: Performs arithmetic-control functions and carries the larger documented +5 V load.
IC600CB525: Provides the Advanced logic function set; it is not the Expanded logic board.

Processing Functions
IC600CB524 performs arithmetic processing for the Series Six Plus CPU and connects to the logic hardware through the documented ribbon cable.
IC600CB525 supplies the advanced logic-control function, so both board identity and the link between them are required for the intended instruction set.
Arithmetic operations and advanced logic execution are divided across the paired boards, making their ribbon connection part of the processor architecture rather than an optional accessory.
Inter-board Connection
The arithmetic board draws thirty +5 V load units and the advanced logic board draws twelve +5 V units.
The ribbon connection carries the inter-board relationship required by the CPU; board position and cable orientation cannot be inferred from the similar faceplate format.
With rack power removed, the inter-board cable is seated in the documented orientation and both board positions are checked before the processor is returned to service.
IC600CB524 / IC600CB525 FAQ
Do IC600CB524 and IC600CB525 perform the same function?
No. CB524 is arithmetic control; CB525 is Advanced logic control.
Why are they installed together for IC600CB524 / IC600CB525?
The Series Six Plus CPU separates arithmetic and logic functions across cooperating boards.
What is the documented +5 V load for IC600CB524 / IC600CB525?
CB524 is 30 units and CB525 is 12 units.
What cable detail matters for IC600CB524 / IC600CB525?
The logic-to-arithmetic ribbon cable must be disconnected and reconnected with power removed and correct orientation.
How is the repaired CPU accepted for IC600CB524 / IC600CB525?
Check diagnostics, execute representative arithmetic/logic instructions and validate the machine sequence.
What must be checked at the ribbon connection for IC600CB524 / IC600CB525?
With power removed, confirm connector orientation, full seating and the correct arithmetic-to-logic board relationship before CPU startup.
Control-function selection
Where several controller boards appear in one family, the service process keeps arithmetic, logic and memory functions as distinct order lines.
