More Information

Overview Manuals Capacity Memory Install Battery

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.

For pricing and availability of the General Electric IC600LX648 48K Combined Memory Module, Apter Power can provide a quotation and relevant GE manuals or product documentation.

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.
Description
The General Electric IC600LX648 Combined Memory Module provides 32K words of logic memory and 16K words of register memory, giving a Series Six Plus CPU a total combined capacity of 48K words.

Logic memory in IC600LX648 stores the user-entered ladder program and mnemonic instructions in 16-bit words with two parity bits. Its register area provides user-accessible storage for data and bit manipulation, including I/O status in expanded operation.

Internal memory on IC600LX648 holds operating tables and scratch-pad data, while battery-backed CMOS preserves the volatile logic and register contents when rack power is removed. The lithium-manganese dioxide battery must be connected before installation unless an approved external auxiliary backup source is used.

Installed in CPU rack slot 4 immediately to the left of the Arithmetic Control module, IC600LX648 presents BATTERY LEVEL and PARITY ERROR indicators so maintenance personnel can distinguish backup condition from stored-data integrity alarms.

Technical notes
Before installing IC600LX648 in slot 4, connect its lithium-manganese dioxide battery or the approved auxiliary backup source so volatile CMOS contents are retained.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can IC600LX648 lose its program after rack power is removed?
IC600LX648 uses volatile CMOS memory, so its lithium battery or an approved external backup source must remain connected during a power loss.
What should be checked when IC600LX648 reports a PARITY ERROR?
For IC600LX648, investigate stored-word integrity and clear the fault only after confirming the memory contents and backup condition.
Can IC600LX648 replace IC600LX680 without reducing controller capacity?
No. IC600LX648 provides 32K logic words and 16K register words, so replacing IC600LX680 would reduce available logic memory.
Why must IC600LX648 be installed in CPU rack slot 4?
IC600LX648 belongs immediately left of the Arithmetic Control module, where the Series Six Plus CPU expects its combined-memory interface.
What does a low BATTERY LEVEL indication mean for IC600LX648?
A low indication means the IC600LX648 backup source needs attention before power is removed, or volatile program and register data may be lost.
When is IC600LX648 suitable for an Expanded II controller?
IC600LX648 meets the Expanded II memory requirement while providing a 48K-word combined allocation for logic and registers.
How can IC600LX648 be serviced without interrupting memory backup?
Connect the approved auxiliary backup to IC600LX648 before removing its battery, and keep rack power isolated while handling the module.
