Description

Product Description

The IC200CPU002 is a higher-capacity CPU module within the GE Fanuc (Emerson) VersaMax family, developed for modular control systems requiring more memory and expanded communication flexibility than entry-level CPUs. It integrates processing, memory management, and serial communications into a compact unit suitable for distributed and standalone PLC architectures.

With increased user memory and support for both Modbus master and slave communication, this CPU is well suited for applications involving data exchange with multiple field devices, operator interfaces, and supervisory systems.

Processing Performance and Memory

• User-configurable memory: 42 KB (program logic, registers, and analog data)

• Execution rate: 1.8 ms per 1K Boolean instructions

• Floating-point capability: Supported

• Runtime overrides: Available

The system uses non-volatile flash for firmware storage combined with battery-backed RAM for application data retention, ensuring continuity during power interruptions.

I/O Handling Capacity

• Discrete Inputs: 2048 channels

• Discrete Outputs: 2048 channels

• Internal Discrete Memory: 1024 bits

• Temporary Logic Bits: 256

• Global Memory Bits: 1280

This configuration supports medium-scale automation systems with distributed I/O structures.

Communication Interfaces

• Built-in ports:

• 1 × RS-232

• 1 × RS-485

• Supported communication protocols:

• SNP Slave

• Modbus RTU Master and Slave

• Serial I/O

The addition of Modbus Master capability allows this CPU to actively poll and control external devices such as drives and instrumentation.

FAQ

Q: What is the main difference between IC200CPU001 and IC200CPU002?
A: The IC200CPU002 provides larger memory (42 KB vs 34 KB) and adds Modbus RTU Master functionality, making it more suitable for complex and communication-intensive applications.

Q: Can this CPU communicate with multiple Modbus devices?
A: Yes. Using the RS-485 port in Modbus Master mode, it can poll and manage multiple slave devices on the same network.

Q: Does the module retain data after power loss?
A: Yes. Battery-backed RAM preserves program and runtime data, and the real-time clock continues operating.
