GE IC200CPU001-MK VersaMax CPU Module
Configured for executing user logic and managing I/O in GE VersaMax PLC systems, the GE IC200CPU001-MK (IC200CPU001-MK CPU Module) provides direct physical/electrical execution across discrete and analog process control nodes. This central processing unit processes up to 2048 discrete inputs and 2048 discrete outputs while handling complex calculations through an onboard 32-bit microprocessor. Dual serial ports facilitate system integration over RS-232 and RS-485 interfaces. The unit retains program structures within configurable flash memory and battery-backed RAM to preserve system operational parameters during supply interruptions.

Deterministic Backplane Bus Communication & Memory Scaling
The CPU module coordinates real-time data flow over the VersaMax backplane bus structure, maintaining deterministic update rates across local and expanded I/O carriers. Onboard firmware manages background processing, internal memory partitioning, and system diagnostics without introducing scan latency into active logic execution loops. System memory supports up to 34 KB of user program storage, register mapping, and analog word allocation, supplemented by 1024 discrete internal bits and 1280 global discrete bits. Real-time clock circuits rely on an internal lithium battery or short-term supercapacitor to keep system timestamps synchronous during complete power shutdowns. High backplane noise rejection prevents electromagnetic interference from corrupting serial communications or bit execution states.
Frequently Asked Questions
Q: How does the CPU handle memory preservation during a primary power outage?
A: An onboard lithium battery maintains RAM contents for up to 6 months without external power, while an internal supercapacitor preserves memory states for approximately 1 hour during brief battery swaps or sudden power drops.
Q: What are the backplane current draw limits required for power supply sizing?
A: The module draws 140 mA at 5 VDC and 100 mA at 3.3 VDC directly from the VersaMax carrier backplane bus during standard processing routines.
Q: Can user programs be loaded onto the module without using a direct programming PC connection?
A: Yes, inserting the optional EZ Program Store device (IC200ACC003) into the serial interface allows direct, offline user program transfers and memory updates without active programming software.
Field Installation Guidelines
Mount the CPU module onto a standard VersaMax carrier sub-rack, ensuring the locking mechanisms click into position to establish proper backplane bus pin alignment. Route RS-232 and RS-485 communications cabling through shielded, twisted-pair wiring conduits, separating signal lines from high-voltage motor circuits to avoid noise induction. Ground the mounting rail directly to the main cabinet panel ground point with a low-impedance conductor. When replacing the lithium backup battery, maintain strict ESD precautions and handle the battery casing with non-conductive tools to prevent accidental shorting across terminal contacts. Verify panel cooling clearance around the module chassis to prevent thermal buildup within industrial enclosures.
