GE IC693CPU364 Series 90-30 Built-in Ethernet CPU Module

Description

Product Introduction

The GE Fanuc IC693CPU364 is an advanced, high-capacity CPU module in the Series 90-30 controller line. It combines the massive 240 Kbytes of configurable memory and 32 MHz processing core of the CPU360 with a native, built-in Ethernet interface, eliminating the need for a separate Ethernet expansion card (like the IC693CMM321) in Slot 2 or 3.

Equipped with an onboard 10Base-T (RJ45) connector, an AAUI port, and an RS-232 Station Manager port right on the front panel, the IC693CPU364 enables direct, high-speed communication with SCADA/HMI systems, programming PCs, and peer-to-peer PLCs over standard TCP/IP network infrastructures using SRTP or Modbus TCP protocols.

Application Scenarios & The “Trench” Experience

At 3:45 AM during a graveyard shift, the central SCADA supervisory station lost connection to a main water reclamation skid. The HMI display turned red with “COMMUNICATION FAILURE” alerts across all bio-reactor aeration tanks. A severe power surge had blown the internal Ethernet MAC layer of the installed IC693CPU364 controller, cutting off network telemetry and halting automated valve actuation. Without real-time dissolved oxygen feedback, the environmental compliance window was rapidly closing.

Application Scenarios

• SCADA & Factory Ethernet Networks: Direct, high-speed Ethernet linking to plant-wide supervisory control (iFIX, Ignition, Wonderware) without extra option cards.
• Large-Scale Batch Process Automation: Manages extensive memory-heavy batch logic, recipe storage, and process logging over Modbus TCP.
• Peer-to-Peer PLC Data Exchange: Coordinates fast inter-PLC handshakes across complex production lines via SRTP messaging.
• Remote Programming & Diagnostics: Allows control engineers to perform online program edits and diagnostic checks remotely over secure factory VPNs.

Field Case Study

A automotive glass lamination facility in Ohio experienced a sudden CPU crash on their primary infrared curing furnace. The legacy CPU364 card suffered internal memory corruption, locking out all communication with the plant’s Ethernet network and stopping the line at a cost of $14,000 per hour. We pulled a fully tested, bench-certified surplus IC693CPU364 from inventory and dispatched it via hot-shot courier. The site technician powered down the rack, dropped the new card into Slot 1, uploaded the backup logic and IP configuration via Proficy Machine Edition, and restored complete SCADA handshakes within 25 minutes of arrival.

Transparency SOP: Quality Assurance & Testing

We test every IC693CPU364 module on live physical hardware and under active Ethernet network loads to ensure 100% field reliability.

1. Inbound Visual Verification: Thorough inspection for casing cracks, bent backplane card-edge pins, damaged RJ45/RJ11 connector tabs, and revision tag authenticity.
2. Modular Rack Power-On Check: Slotted into Slot 1 of an active GE IC693CHS392 10-slot rack driven by an IC693PWR330 power supply to verify MODULE OK, RUN, and LAN ONLINE LED diagnostic sequences.
3. Ethernet Ping & Protocol Stress Test: Connected to a local Ethernet switch; executed a 5,000-packet continuous ping test and loaded a heavy SRTP/Modbus TCP data read/write cycle for 4 hours to verify zero packet loss and zero thermal drift.
4. Full 240 KB RAM & Expansion Sweep: Downloaded a 240 KB memory-filling test program in Proficy Machine Edition, executing continuous scan loops across attached local expansion baseplates (IC693CHS391).
5. ESD Sealing & Final QC: Memory cleared to factory defaults, IP configuration reset, diagnostic logs cleared, and the card sealed inside heavy-duty ESD shielding with custom protective foam packaging.

The Veteran’s Tech Trap Guide

• ⚠️ Must Mount in Slot 1 Only: The must be installed in Slot 1 of a modular CPU baseplate (IC693CHS392 or CHS393). It will not operate in an option slot, nor can it be installed on embedded CPU baseplates (such as the IC693CHS397). Attempting to mount it in an incorrect chassis will prevent system power-up.
• ❗ Never Hot-Swap the CPU Module: The GE Series 90-30 backplane is not hot-swappable! Inserting or pulling the while the rack power supply is energized can arc the backplane connector pins, ruin internal 3.3V/5V logic transceivers, or corrupt user memory. Always turn off main rack power first.
• ⚠️ Store IP Configuration Before Removal: Unlike standalone Ethernet cards, the IP address on the CPU364 is stored inside the CPU’s hardware configuration file. If you swap out a dead CPU card without knowing its original IP address or having a saved Proficy project file, you must assign the IP address via the RS-232 Station Manager port before SCADA communications will reconnect.
• ❗ Watch Power Supply 5V Rail Requirements: The draws significantly more current from the backplane 5V DC supply (~1.2A) than standard non-Ethernet CPUs due to its onboard network PHY chip. Ensure your rack power supply (prefer IC693PWR330 high-capacity over PWR321) has adequate overhead, especially when populating high-density I/O cards.

Frequently Asked Questions (FAQ for Conversion)

Q: What is the main advantage of the over the IC693CPU360?

A: The features an integrated Ethernet interface directly on the module face, supporting SRTP and Modbus TCP protocols without requiring a separate Ethernet expansion card (like the IC693CMM321).

Q: Is the GE Fanuc hot-swappable?

A: No. You must turn off main incoming power to the Series 90-30 baseplate before removing or installing the module to prevent electrical damage.

Q: Can I use both the RJ45 port and the AAUI port simultaneously?

A: No. The CPU364 supports one physical Ethernet connection at a time. The module automatically selects the active physical port based on network link detection.

Q: How do I assign an IP address to the ?

A: The IP address, subnet mask, and gateway are assigned within the Hardware Configuration settings in Emerson/GE Proficy Machine Edition or VersaPro software, or manually configured using a terminal emulator connected to the RS-232 Station Manager port.

Q: What warranty coverage comes with this surplus Ethernet CPU module?

A: Every module is backed by a full 12-month replacement warranty. All units are authentic GE Fanuc surplus equipment, thoroughly cleaned, inspected, and bench-tested under continuous Ethernet network traffic prior to shipment.
