Emerson IC695CPE302-BBAB RX3i Controller
A B-series CPE302 backplane controller with 2 MB user memory, two Gigabit Ethernet ports and firmware release 10.76.
Product Overview
IC695CPE302-BBAB is a PACSystems RX3i CPE302 B-series controller. It performs real-time machine and process control from the universal backplane and communicates with programming, HMI/SCADA and remote systems through embedded Ethernet and serial interfaces.
The BBAB release is identified with firmware 10.76 in the manufacturer release history. B-series hardware has a different platform and firmware boundary from earlier A-series controllers, so the complete suffix must remain in the replacement record.
Performance
- Executes control logic written in Ladder Diagram, Structured Text, Function Block Diagram or C.
- Supports secure OPC UA and PAC Security Center certificate management.
- Provides two internally switched Gigabit Ethernet ports for plant and programming communications.
- Uses an IC695ACC400 Energy Pack to save user memory to non-volatile storage during power loss.

System Integration
- Use PAC Machine Edition and the correct target/firmware package for the B-series controller.
- Back up the full project, hardware configuration, passwords/certificates and Ethernet settings.
- Verify the Energy Pack, RTC battery, USB/RDSD media and every I/O/option module.
- Stage network, I/O and machine testing before releasing the replacement CPU to production.
Applications
- Real-time machine, process and material-handling control.
- RX3i systems requiring Gigabit Ethernet, OPC UA and modular backplane I/O.
- Replacement of the exact CPE302 B-series hardware and firmware generation.
FAQ
Why must IC695CPE302-BBAB not be replaced with an A-series CPE302 without review?
The B-series uses a new hardware platform and incompatible firmware boundary, so project, firmware, ports and migration procedure must be checked.
What project assets should be exported before changing IC695CPE302-BBAB?
Save the PAC Machine Edition project, hardware configuration, force tables, passwords/OEM keys, certificates, Ethernet settings, RDSD files and fault tables.
How should the two Ethernet ports on IC695CPE302-BBAB be evaluated?
They are an internal switch, so topology, loops, MRP design, IP addressing and external-switch behavior must be reviewed rather than treating them as two isolated interfaces.
What maintenance item is separate from the Energy Pack on IC695CPE302-BBAB?
The real-time-clock battery has its own replacement schedule; a healthy Energy Pack does not prevent clock reset after RTC-battery failure.
What acceptance test should follow an IC695CPE302-BBAB exchange?
Verify firmware and project checksum, I/O, Ethernet/serial protocols, OPC UA certificates, memory retention, clock, diagnostics, safety interlocks and controlled machine sequences.
