Functional Role & Application Analysis
The GE IC693CPU374-GP is a high-performance central processing unit designed for the Series 90-30 PLC platform. It solves the critical need for fast, deterministic control combined with native network connectivity in mid-tier automation applications. By integrating a dual-port Ethernet switch directly onto the CPU, it eliminates the need for a separate communication coprocessor module, saving a valuable rack slot and reducing overall system cost. The 133 MHz processor and 240 KB of configurable memory provide ample headroom for complex logic, floating-point math, and extensive data handling.
- Use Case 1: Serving as the primary controller for mid-sized manufacturing lines, packaging machines, or water/wastewater treatment stations requiring high-speed logic and native Ethernet connectivity.
- Use Case 2: Acting as the network hub in a distributed control architecture, utilizing its built-in Ethernet switch to daisy-chain HMI panels, VFDs, and other PLCs without requiring external network switches.
- Use Case 3: Upgrading legacy Series 90-30 systems that are experiencing scan-time bottlenecks or lack modern Ethernet connectivity, providing a direct drop-in replacement for older, slower CPUs.
Our Quality Standard & Testing Process
A CPU failure stops your entire process. We know the cost of downtime is measured in thousands of dollars per hour. That’s why we don’t just ship parts; we ship verified, operational controllers. Every IC693CPU374-GP undergoes a rigorous, multi-stage validation process in our lab to ensure it will boot, communicate, and execute logic flawlessly on your factory floor.
- Visual & Component Inspection: Every unit is inspected for physical damage, corrosion on the backplane connector, and integrity of the dual Ethernet ports. We verify the model number and revision against GE documentation.
- Live System Test: The CPU is installed in a live Series 90-30 test rack with a known-good power supply. We apply power and verify successful boot-up, no fault LED indicators, and proper recognition of attached I/O modules.
- Logic & Communication Test: We download a test program to verify logic execution speed and memory integrity. We also connect via Ethernet to confirm SRTP/EGD communication, IP assignment, and data exchange with a test PLC or PC.
- Warranty Backing: Only CPUs that pass all functional, logic, and network tests are approved for shipment and are backed by our full 12-month warranty.

Compatibility & Migration Paths
Do not assume this CPU is a direct swap for any other Series 90-30 processor. The 374 has specific memory, port, and firmware requirements. Installing an incompatible CPU or mismatching firmware versions is a common and costly mistake. Verify these points before purchasing.
- Software Compatibility: This CPU requires VersaPro 2.03 or later, or Proficy Machine Edition Logic Developer 2.60 or later. Older programming software will not support it.
- Ethernet Configuration: The dual Ethernet ports share a single IP address. Ensure your network architecture accounts for this shared-address switch topology when configuring EGD exchanges or SRTP connections.
- Battery Backup: The CPU relies on an internal battery for clock and memory retention. Verify your power supply provides the required 7.4W at 5VDC, and consider an external battery pack (IC693ACC302) if extended backup is needed.
