GE Fanuc IC610CPU105 / IC610CPU106 Series One Plus CPU Modules
Series One Plus CPUs with a clear memory distinction between the 700-word and 3.7K configurations.
Product Overview
GE Fanuc IC610CPU105 and IC610CPU106 are Series One Plus central processing modules that scan ladder logic, process data operations and control the rack I/O, with different program-memory capacities.
Both CPUs belong to the Series One Plus platform and use the expanded instruction set. They share rack, I/O and programming conventions but not program-memory capacity.
IC610CPU105: Standard Series One Plus CPU with 700 words of CMOS memory.
IC610CPU106: Series One Plus 3.7K CPU with 3,700 words of CMOS memory; intended for larger programs.

Product Features
IC610CPU105 provides the Series One Plus data-operation instruction set in the standard memory configuration and can be expanded beyond its supplied 700-word CMOS capacity.
IC610CPU106 increases program space to 3,700 words so larger programs can use data operations without the smaller CPU's memory boundary.
Both modules use the Series One Plus programmer path and expanded data instructions, but the saved program must remain within the installed CPU's memory limit before it can be restored.
Timer Operation and Scan Performance
IC610CPU106 can select a 0.01-second timer base by setting output 770; that choice applies to all timers in the program and cannot be mixed with 0.1-second timers.
A full 3.7K-word program has a documented typical scan time of 36 ms, while IC610CPU105 remains the lower-capacity Series One Plus CPU.
Program storage may use CMOS RAM or PROM, so the CPU identity, memory medium and global timer-base selection must be recorded as one operating configuration.
IC610CPU105 / IC610CPU106 FAQ
Can an IC610CPU105 program always be moved to IC610CPU106?
Capacity is greater on CPU106, but compatibility still depends on the actual program, I/O and hardware configuration.
Can a 3.7K program fit in IC610CPU105 for IC610CPU105 / IC610CPU106?
No. IC610CPU105 has 700 words standard, while IC610CPU106 provides 3,700 words.
Which programmer is required for IC610CPU105 / IC610CPU106?
The GE catalog table identifies IC610PRG105 as required for Series One Plus.
What is the documented typical scan time for a full 3.7K program for IC610CPU105 / IC610CPU106?
The manual gives a typical 36 ms scan for a 3.7K-word program.
What records should accompany a CPU spare for IC610CPU105 / IC610CPU106?
Keep the complete catalog number, memory arrangement, program backup, rack layout and I/O map.
Which capacity record prevents an IC610CPU105 / IC610CPU106 mismatch?
Record the compiled program size and whether the installed CPU is the 700-word IC610CPU105 or the 3,700-word IC610CPU106.
