IC693CPU372 Single-Slot Modular CPU 133MHz GE Fanuc Series 90-30

Product Overview

The IC693CPU372 is a high-performance single-slot central processing unit engineered for the Series 90-30 modular PLC platform by GE Fanuc.

Driven by an AMD SC520 processor running at 133 MHz clock speed, this 32-bit module executes complex Boolean operations in just 0.15 milliseconds per 1K logic block.

The controller integrates dual auto-sensing 10/100 Mbps RJ-45 Ethernet interfaces that function as an internal switch, enabling linear daisy-chain and Device Level Ring (DLR) network topologies without requiring external network switches.

It supports up to 240 Kbytes of user program memory with battery-backed RAM or non-volatile Flash storage options, making the IC693CPU372 ideal for large-scale industrial control architectures.

System Installation & Hardware Integration

Mount the IC693CPU372 in Slot 1 of any standard Series 90-30 baseplate, directly adjacent to the power supply unit.

Ensure the rack bus backplane power is fully isolated prior to seating or unseating the module in the chassis.

Connect Ethernet cabling using shielded CAT5e or CAT6 Twisted Pair wires to prevent electromagnetic noise coupling.

Maintain proper battery backup connections to prevent total user memory loss during complete system power shutdowns.

Platform Compatibility & Operational Protocols

The IC693CPU372 communicates smoothly with PACSystems equipment, VersaMax remote I/O nodes, and legacy hardware.

Integrated software configurations run through Proficy Machine Edition Logic Developer PLC programming packages.

Supports up to three joined Ethernet option modules within the local chassis to expand network gateway capabilities.

Diagnostic Capabilities & System Surveillance

An integrated web server allows field engineers to perform remote system diagnosis and network status monitoring using any standard browser.

Front-panel LED status indicators provide immediate feedback for CPU operation, memory health, battery condition, and Ethernet link/activity status.

A dedicated Station Manager connector enables direct serial diagnostic tracing during deep protocol troubleshooting.

Commissioning, Maintenance & Logistics

Quick configuration can be deployed using the built-in web management interface or Proficy software environments.

Dedicated hardware reset switches and main control switches streamline field commissioning and fault recovery workflows.

Target Equipment & Practical Application Scenarios

High-speed motion control and continuous loop regulation in automated material handling networks.

Real-time data exchange across distributed pumping stations using Ethernet Global Data (EGD) messaging.

Process automation control systems in water treatment plants and power distribution substations.

Global PLC Spare HUB's Insight & Field Experience

Field installations reveal that network dropouts on the dual Ethernet ports are frequently tied to duplicate IP assignments across the local subnet.

During a system overhaul at a metal processing plant, the CPU experienced intermittent SRTP communication timeouts during heavy data logging cycles.

Using the onboard Station Manager interface, field engineers diagnosed high network packet collisions caused by unmanaged switch loops in the cabinet network.

Implementing a Device Level Ring (DLR) structure across the two auto-sensing ports of the IC693CPU372 restored network stability completely, eliminating communication latencies.

Selection & Application Guidance

Select the IC693CPU372 if your legacy control architecture requires embedded dual Ethernet ports without relying on separate daughterboards.

For applications needing larger memory structures or higher processing speeds, consider upgrading to the PACSystems RX3i CPU platform.

Frequently Asked Questions

Question 1: How do I configure IP settings on the CPU module during initial commissioning?

Answer: Use Proficy Machine Edition or access the onboard web server via a direct Ethernet connection to set the static IP address.

Question 2: What is the primary operational function of the dual Ethernet ports on this unit?

Answer: They act as an embedded unmanaged switch with a single IP address, supporting daisy-chaining and ring network architectures.

Question 3: Will the module retain stored logic programs if the internal battery completely fails?

Answer: RAM memory will clear, but program code remains permanently safe if backed up to an optional Flash non-volatile memory card.

Question 4: Can the CPU interface directly with Modbus TCP field devices without third-party converters?

Answer: Yes, the built-in firmware supports native Modbus TCP Server and Client protocols directly over the Ethernet interface.

Question 5: What causes the main STATUS LED to blink rapidly during bootup?

Answer: A rapid blinking red LED typically indicates a memory checksum fault, corrupt user logic, or an unassigned system IP configuration.
