Emerson / GE Fanuc IC693CPU374-HX CPU374 PLUS Ethernet Controller, HX Revision
A single-slot Series 90-30 CPU374 PLUS controller with embedded switched Ethernet and an exact HX hardware revision identity.
Overview
Emerson / GE Fanuc IC693CPU374-HX identifies a Series 90-30 CPU374 PLUS Ethernet controller carrying the HX hardware revision. The base CPU374 architecture combines a 133 MHz embedded 586 processor, 240 KB of user memory and two 10/100 Ethernet ports through an internal switch.
The complete HX suffix must remain attached to the spare record. Published CPU374 family data describes the controller platform, while firmware, hardware revision and the installed project determine the exact replacement boundary.
A migration or exchange should preserve the program, hardware configuration, Ethernet addressing, produced/consumed exchanges and battery-backed data before the original CPU is disturbed.
Specifications
Features
Embedded Ethernet
Two external ports share the CPU embedded interface and support a switched network connection.
Program storage
Battery-backed RAM and Flash support controlled program retention and backup practices.
High-speed execution
The published 133 MHz processor platform supports the CPU374 PLUS control workload.
Revision-controlled identity
HX remains part of the exact label and must be matched with firmware and project evidence.
Applications
Legacy machine control
Maintaining a Series 90-30 application that already uses CPU374 embedded Ethernet.
Networked PLC service
Preserving one IP identity, switched Ethernet cabling and the approved exchange configuration.
Controlled CPU replacement
Restoring a validated project only after hardware and firmware compatibility are confirmed.
Lifecycle
Archive
Capture logic, hardware configuration, IP settings, exchange tables, firmware and battery-backed values.
Match
Verify HX label, power supply, rack, option modules and engineering-software support before transfer.
Commission
Restore the approved image, then prove I/O, Ethernet peers, time, retained data, alarms and safe sequences.

FAQ
Can IC693CPU374-HX be selected from the CPU374 name alone?
No. The HX revision, firmware, rack supply, project and network configuration must be verified as one replacement boundary.
What network evidence should accompany IC693CPU374-HX?
Provide IP settings, port cabling, SRTP or EGD relationships, switch path, peer list and the approved controller backup.
Why does IC693CPU374-HX require a high-capacity power supply check?
CPU374 family controllers are specified for the high-capacity Series 90-30 supply, so the installed supply and rack load must be confirmed.
How should the two Ethernet ports on IC693CPU374-HX be documented?
Record both physical connections while treating them as ports of one embedded switched interface with one controller IP identity.
What proves IC693CPU374-HX is ready after replacement?
Confirm the exact restored project, stable I/O, all Ethernet sessions, retained data, clock, diagnostics, interlocks and machine safe-state tests.
