Description

Overview

The IC200CPU005 is a VersaMax-series programmable controller CPU developed by GE Fanuc Emerson, designed for compact automation systems requiring scalable control logic and modular expansion capability.

It functions as the central processing unit of a VersaMax rack, coordinating I/O modules, executing control logic, and managing serial communications for field devices. The unit is suitable for standalone machines as well as distributed control applications with moderate I/O requirements.

Core System Capabilities

• Supports up to 64 VersaMax I/O modules

• Maximum system capacity: 2048 discrete and analog I/O points

• Local I/O handling: up to 256 points directly

• Integrated real-time clock with battery-backed retention

• Program storage using non-volatile flash memory

Processing Performance

• Boolean execution speed: approx. 0.8 ms per 1K logic instructions

• Floating-point arithmetic supported for advanced calculations

• Deterministic scan behavior suitable for time-critical control tasks

• Optimized for small to mid-size machine control cycles

Memory Architecture

• User memory: 64 KB configurable space

• Logic program area

• %R registers

• %AI / %AQ data tables

• Battery-backed RAM for data retention and system variables

• Flash memory for permanent program storage

• Supercapacitor backup maintains volatile memory temporarily (approx. 1 hour without battery power)

• Battery life expectancy: up to ~5 years (typical)

Communication Interfaces

The CPU integrates two independent serial communication channels:

• RS-232 port for programming, diagnostics, and firmware updates

• RS-485 port for field communication and device networking

Supported protocols include:

• SNP / SNP-X for GE system communication

• Modbus RTU master functionality (firmware dependent)

Firmware upgrades are supported via RS-232 interface only.

I/O Expansion Capacity

• Maximum I/O modules: 64

• Total system I/O capacity: up to 2048 points

• Expansion flexibility suitable for distributed rack configurations

• Compatible with full VersaMax I/O family modules

Electrical and Power Characteristics

• Backplane current draw: ~35 mA at 5 VDC (base operation)

• Up to ~135 mA at 5 VDC with serial accessories attached

• Designed for low-power backplane operation in modular racks

Mechanical and Installation

• DIN rail mounting: 35 mm standard (EN 50022)

• Installation requires grounded, unpainted conductive rail

• Integrated Run/Stop hardware switch for local control

• Compact CPU form factor designed for single-slot installation

Weight: 0.4 lbs

Environmental Ratings

• Operating temperature: 0°C to 60°C

• Designed for enclosed control cabinet environments

• Stable operation under industrial vibration and electrical noise conditions when properly grounded

Applications

• Compact machine automation systems

• Standalone process control units

• Conveyor and packaging machines

• Pump and HVAC control systems

• Small distributed I/O architectures

FAQ

Q1: Can this CPU handle analog and digital expansion together?
Yes, it supports mixed I/O configurations across all compatible VersaMax modules.

Q2: Is Modbus supported natively?
Modbus RTU support is available depending on firmware version.

Q3: Can the system run without a battery?
Yes, but program and data retention will be limited without battery or capacitive backup.
