Features:
- Retains 8K words of Series Six internal data in battery-backed CMOS memory.
- Separates status, override, transition-table, and scratchpad storage.
- Provides BATTERY and PARITY indications for maintenance checks.
IC600CB504 preserves internal controller information that must survive a normal power interruption.
Its backplane switch settings tell the CPU how the total logic-memory space is arranged in 2K increments.
A controlled replacement therefore combines electrical handling with a saved record of retained tables, memory mapping, and restart expectations.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Match the installed memory arrangement
- Module position: The backplane DIP-switch bank defines the amount and location of Series Six logic memory in 2K increments.
- Operational effect: IC600CB504 cannot be moved between positions without checking that map.
- Memory location: A Model 600 CPU uses the A memory location.
- Memory condition: A Model 6000 system can extend through A, B, C, and D, with no more than 8K assigned to one logic-memory slot.
- Switch record: Record the switch pattern and fitted module order before removal so the replacement can be verified independently.
Protect more than the ladder program
- Program record: IC600CB504 retains status, override, transition-table, and scratchpad information.
- Signal mode: These data influence how the controller resumes even when the program source itself is available elsewhere.
- Battery condition: The lithium battery preserves CMOS contents after power is removed.
- Battery response: Treat a BATTERY warning as a reason to capture the current state before maintenance, not simply as a lamp to clear.
- Memory state: After service, compare retained values and overrides with the authorized restart plan.
Use the PARITY indication in context
- Parity response: The PARITY lamp reports a memory-access problem while the module is operating in a powered CPU rack.
- Operational effect: A new or cleared module may also require the required initialization sequence.
- Fault evidence: Check module seating, switch configuration, and expected contents before replacing additional hardware.
- Message path: Preserve the fault state and any Workmaster message for the maintenance record.
- Memory state: Only return the controller to automatic operation after the intended memory map and retained data are confirmed.
Control power and static exposure
- Safe handling: Power down the Series Six CPU before inserting or removing IC600CB504.
- Connector condition: Use the specified extraction tool and avoid touching CMOS circuitry or connector contacts.
- Battery condition: Confirm the battery connection and switch positions before the module is seated.
- Backplane check: Inspect the card guides and backplane connector for damage or contamination.
- Parity response: At power-up, verify BATTERY and PARITY status, confirm the recognized memory size, and perform a controlled restart with outputs supervised.
