Emerson / GE Fanuc IC693CPU372-AE Series 90-30 CPU372 PLUS Ethernet Controller
A CPU372 PLUS controller with embedded switched Ethernet; the complete -AE release identity is retained for replacement review.
Overview
Emerson / GE Fanuc IC693CPU372-AE is a series 90-30 cpu372 plus ethernet controller identified by the complete submitted ordering string. Its suffixes and revision fields remain part of the supply identity.
Selection of IC693CPU372-AE should be based on the installed label, host-system record and the verified interface details below; neighboring family numbers are not treated as interchangeable.
Engineering Data
Functions
The controller combines Series 90-30 CPU execution and embedded Ethernet connectivity in one catalog identity.
The two physical Ethernet ports provide an integral switch rather than two separately configured controller interfaces.
Station Manager supports Ethernet-interface diagnostics and controlled troubleshooting.
The -AE suffix remains visible so hardware and firmware records can be compared before exchange.
Applications
- Like-for-like service of an installed IC693CPU372-AE controller.
- Ethernet-connected Series 90-30 control applications with approved project and firmware records.
- Migration planning where the original rack, power supply and I/O configuration must first be documented.
Lifecycle & Service
- Back up the PLC project, variables and Ethernet configuration before removing IC693CPU372-AE.
- Record CPU firmware, Ethernet firmware, rack slot, power supply and connected network topology.
- Load only the approved project with compatible engineering software and firmware.
- Test communications, I/O, retentive data, time functions and machine interlocks before operation.
FAQ
What must be backed up before replacing IC693CPU372-AE?
Save the complete PLC project, hardware configuration, Ethernet parameters, variables and any application-specific retentive records.
Do the two Ethernet ports on IC693CPU372-AE require separate IP addresses?
No. They are switched physical ports on the embedded Ethernet interface; confirm the single configured interface identity in the project.
Why must both firmware records be checked for IC693CPU372-AE?
The CPU and embedded Ethernet interface have compatibility boundaries that can affect project loading, communications and diagnostics.
Can IC693CPU372-AE be installed without reviewing rack power?
No. Verify the installed Series 90-30 power supply and total rack load before fitting the replacement controller.
What proves IC693CPU372-AE is ready for service?
A controlled acceptance should confirm project checksum, Ethernet communications, I/O operation, retained data and every required interlock or safety interface.
