ABB IC698CRE030

Description

Product Description

The ABB IC698CRE030 is a high-performance central processing unit (CPU) module for the GE Fanuc Series 90-70 PLC platform, now supported and supplied by ABB as part of its industrial automation portfolio. This module serves as the main controller for the Series 90-70 system, executing the user program, managing I/O communications, and coordinating all system functions. The IC698CRE030 is part of the enhanced “RX7i” series, offering improved performance and memory over earlier 90-70 CPUs. Integrating the ABB IC698CRE030 as the system CPU provides a powerful and reliable control engine for complex automation applications.

• Programmable Logic Languages: Supports all standard IEC 61131-3 languages (Ladder Logic, Function Block Diagram, Structured Text, etc.) via Proficy Machine Edition software.

Advantages and Features

1. Enhanced Processing Power: The ABB IC698CRE030 offers significant performance improvements over standard 90-70 CPUs, enabling faster scan times and handling of more complex control algorithms, which is critical for large-scale or high-speed applications.
2. Integrated Ethernet Connectivity: The built-in Ethernet port simplifies network integration, allowing for easy programming, remote monitoring, data exchange with HMIs/SCADA, and peer-to-peer communication with other controllers without the need for an additional communication module.
3. Backward Compatibility and Rugged Design: As part of the RX7i series, it maintains compatibility with the extensive installed base of Series 90-70 I/O and racks. It is built with industrial-grade components for reliable operation in demanding environments.
4. Large Memory Capacity: The substantial user memory allows for the development of extensive control programs with extensive documentation, data logging, and complex sequencing, supporting sophisticated automation strategies.
5. Proven Architecture with Modern Features: It combines the robustness and vast I/O ecosystem of the Series 90-70 platform with modern communication capabilities, providing a reliable upgrade path for legacy systems and a solid foundation for new installations.

Application Cases in Various Fields

• Automotive Manufacturing: Controls large transfer lines, robotic welding cells, and paint shops where high-speed logic and coordination of hundreds of I/O points are required.
• Material Handling Systems: Serves as the central controller for complex conveyor networks, automated storage and retrieval systems (AS/RS), and airport baggage handling systems.
• Water and Wastewater Treatment: Manages plant-wide control logic for large treatment facilities, coordinating pumps, valves, and chemical dosing across multiple remote I/O houses.
• Food and Beverage Processing: Controls batch and continuous processes in large production lines, handling extensive recipe management and sequential control.

Comparison with Competing Products

• vs. Older Series 90-70 CPUs (e.g., IC693CPU350): The IC698CRE030 offers significantly faster processing, larger memory, and integrated Ethernet, providing a clear performance and connectivity upgrade while maintaining I/O compatibility.
• vs. Newer PACSystems RX3i CPUs: The RX3i platform is the direct successor. The IC698CRE030 (RX7i) serves as a high-performance option within the 90-70/RX7i lineage, often chosen for system upgrades where reusing existing 90-70 I/O infrastructure is a priority to minimize cost and disruption.
• vs. PLCs from Other Brands (Siemens S7-400, Rockwell ControlLogix): Competing platforms offer similar high-end capabilities. The choice often depends on existing plant standards, technician familiarity, and the specific requirements of the installed I/O system (particularly the Genius bus).

Selection Suggestions and Precautions

1. Rack and Power Supply Compatibility: The IC698CRE030 requires a Series 90-70 or RX7i compatible rack (e.g., IC698) and a sufficiently powerful power supply module. Verify compatibility with your specific rack model.
2. Battery for Memory Backup: The CPU uses a lithium battery to retain the program and real-time clock during power loss. Regularly check and replace the battery (typically every 2-5 years) to prevent program loss.
3. Genius Bus Configuration: If using Genius I/O, a Genius Bus Controller (GBC) module is required in the rack. The network configuration (baud rate, device addresses) for all Genius blocks must be correctly set in the Proficy Machine Edition hardware configuration.
4. Firmware Version Management: Ensure the firmware of the IC698CRE030 is compatible with the version of Proficy Machine Edition software you are using for programming. Using mismatched versions can cause communication or functionality issues.
5. Heat Dissipation: High-performance CPUs generate heat. Ensure adequate ventilation in the control cabinet and do not obstruct the airflow around the module.
