GE IC600LX648K / IC600FP608K – Series Six PLC Memory Module | GE Series Six Platform
Engineering Background
The GE Series Six Programmable Logic Controller platform was engineered for heavy-duty industrial process control environments where deterministic scan times, robust I/O handling, and long-term field reliability are non-negotiable. Introduced as part of GE Automation’s flagship PLC family, the Series Six architecture remains deployed across power generation, petrochemical, water treatment, and discrete manufacturing facilities worldwide. Memory modules within this platform serve as the primary program and data storage medium, directly governing controller execution integrity.
Product Positioning
The IC600LX648K and IC600FP608K are functionally paired memory modules designed for the GE Series Six CPU rack. The IC600LX648K provides expanded logic/program memory capacity, while the IC600FP608K serves as the companion floating-point or extended data memory module. Together they extend the controller’s addressable memory space to support complex ladder logic programs, data table registers, and floating-point arithmetic routines — critical for advanced PID loops, recipe management, and multi-axis sequencing applications. Konmask.com sources these modules from verified surplus channels and offers them as a cost-effective, OEM-specification alternative to new procurement.

System Architecture & Signal Flow
Within the GE Series Six rack, the CPU module interfaces with memory modules via the internal backplane bus. The IC600LX648K occupies the logic memory slot and stores the user ladder program, I/O configuration tables, and system parameters. The IC600FP608K resides in the data/floating-point memory slot and holds register data, floating-point accumulators, and extended data tables. During each scan cycle, the CPU reads program instructions from the LX648K, executes arithmetic and logic operations using data held in the FP608K, updates I/O image tables, and writes outputs — all within the deterministic scan window defined by the CPU configuration. Battery-backed CMOS ensures all stored data persists across power cycles without re-download from the programming terminal.

Technical FAQ
Q: Can IC600LX648K and IC600FP608K be used independently?
A: The LX648K (logic memory) is required for CPU operation. The FP608K is required only if your application uses floating-point instructions or extended data tables. Consult your GE Series Six CPU manual for slot requirements.
Q: Is the battery included?
A: No. Battery-backed CMOS retention depends on the host CPU’s battery. Inspect and replace the CPU battery before installing new memory modules to prevent data loss.
Q: Will my existing program be preserved after module swap?
A: No. Replacing memory modules clears stored program data. A full program re-download from your programming terminal (e.g., Logicmaster 6) is required after installation.
Q: Do you provide a test report?
A: Yes. A Konmask functional test certificate is included with each shipment. Additional OEM test documentation can be requested prior to purchase.
Q: What is the lead time?
A: In-stock units ship within 1 business day from Xiamen, China. Contact us to confirm current stock status before placing time-critical orders.
Q: Can you supply other GE Series Six modules?
A: Yes. Konmask.com maintains an extensive inventory of GE Series Six CPU, I/O, power supply, and communication modules. Contact us with your full BOM for a consolidated quote.
