General Electric IC693CPU374 Processor Module

The GE IC693CPU374 serves as a high-performance central processing unit for the Series 90-30 Programmable Logic Controller system. This module utilizes an embedded 133 MHz 586 microprocessor to manage complex industrial automation sequences. By integrating a powerful logic engine with built-in networking, the controller eliminates the need for external communication cards. It occupies only one rack slot while providing comprehensive control over local and remote I/O. Facilities utilize this processor to achieve high-speed Boolean execution and reliable data handling.

Primary Technical Characteristics

Advanced Processing and Memory Logic

This CPU provides a significant 240KB memory pool to store sophisticated application code and configuration data. Users can customize the allocation of register memory to fit specific process requirements. For example, the system supports extensive analog I/O mapping alongside thousands of internal timers and counters. Because the 133 MHz processor handles logic so efficiently, it maintains a fast 0.15 ms scan rate. This rapid execution ensures precise timing for high-speed packaging, assembly, and motion control applications.

Integrated Networking and Connectivity

The IC693CPU374 features an embedded Ethernet interface with two auto-sensing 10/100 Mbps ports. These ports allow the PLC to communicate simultaneously with programming software, HMI panels, and SCADA systems. Furthermore, the module supports the SRTP and Ethernet Global Data (EGD) protocols for seamless network integration. For legacy serial connections, the unit communicates via the power supply using SNP and SNPX protocols. This dual-network approach ensures the controller acts as a central hub for all factory floor data.

Configuration and System Maintenance

Engineers program this processor using VersaPro 2.03 or CIMPLICITY Machine Edition Logic Developer 2.60 and later. These platforms enable real-time online editing to minimize process interruptions during logic updates. Additionally, the module includes front-facing LED indicators for power, run status, and network activity diagnostics. Proper maintenance involves verifying the battery health to protect the volatile memory during power cycles. The robust design ensures a long service life within demanding DCS and PLC environments.
