Features:
- IC600LX648 provides 32K logic words and 16K register words.
- Parity-protected 16-bit storage supports program and data integrity.
- Battery-backed CMOS retains contents when rack power is removed.
The module combines logic, register, and internal-memory functions in a single Series Six Plus CPU board.
Separate logic and register allocations preserve the controller's program space while providing user-accessible data storage.
BATTERY LEVEL and PARITY ERROR indicators help maintenance personnel distinguish backup condition from stored-data integrity faults.

Mapping the 48K combined capacity
- Logic: IC600LX648 provides 32K words for the user program.
- Register: A separate 16K-word area holds accessible operating data.
- Total: The two documented allocations give 48K words of combined capacity.
- Higher option: IC600LX680 raises logic capacity to 64K while retaining 16K registers.
Separating the three memory functions
- Logic memory: Stores ladder logic and mnemonic instructions.
- Register memory: Supports user data and bit-manipulation functions.
- Internal memory: Holds operating tables and scratch-pad data.
- Parity: Two parity bits accompany each 16-bit logic and register word.
Installing the combined memory board
- Rack position: Insert IC600LX648 in CPU slot 4.
- Adjacency: Slot 4 is immediately left of the Arithmetic Control module.
- Faceplate: Refit the faceplate marked LOGIC MEMORY after board insertion.
- Power: Reserve 5 VDC backplane capacity for the documented module load.
Protecting volatile CMOS contents
- Internal battery: Connect the lithium-manganese dioxide battery before installation.
- External backup: An approved auxiliary source can replace the internal connection.
- Indicator: BATTERY LEVEL provides a direct warning of backup condition.
- Outage planning: Preserve the program before disturbing a weak or disconnected battery.
