Emerson IC693CPU372 Series 90-30 Ethernet CPU
A single-slot Series 90-30 PLUS controller with embedded 10/100 Ethernet for legacy rack control and network integration.
Product Profile
IC693CPU372 is a Series 90-30 CPU372 PLUS controller with an embedded Ethernet interface. It executes the PLC application, exchanges process data over Ethernet and provides Station Manager diagnostics within the supported Series 90-30 architecture.
The base identifier does not include the hardware suffix. Preserve the complete label because firmware, Ethernet capabilities and revision-specific operational notes must be matched during replacement.

System Role
- Executes machine or process logic in a Series 90-30 rack.
- Connects the controller project to Ethernet programming, HMI and peer-data services.
- Manages configured reference memory and installed Series 90-30 modules.
- Provides network diagnostic access through the embedded Ethernet Station Manager.
Compatibility
- Match the complete hardware suffix and firmware to the archived project.
- Confirm every I/O, communications and intelligent module in the rack before exchange.
- Retain IP parameters, EGD producer/consumer definitions and SRTP channel settings.
- Review power-supply capacity, battery retention and expansion-rack cabling.
Applications
- Legacy Series 90-30 automation with embedded Ethernet.
- Machine and process cells exchanging EGD or SRTP data.
- Controlled maintenance while planning migration to PACSystems RX3i.
FAQ
Which missing detail prevents an exact IC693CPU372 quotation?
The hardware suffix and firmware release are required because the base number alone does not identify the installed revision.
What should be uploaded before changing IC693CPU372?
Save the complete controller project, hardware configuration, reference tables, IP settings, EGD exchanges, communication requests and fault information.
How should an IC693CPU372 replacement be checked for Ethernet continuity?
Compare live IP settings, EGD exchange status, SRTP connections, Station Manager logs and HMI communications with the archived network plan.
Can IC693CPU372 be replaced by a CPU374 because both are Series 90-30 Ethernet CPUs?
Do not assume interchangeability. Project support, hardware revision, communications behavior and rack compatibility require a documented engineering review.
What information helps plan migration away from IC693CPU372?
Provide the I/O inventory, logic size, scan time, special modules, network services, expansion racks, HMI links and required downtime window.
