Engineering Advantages
- Universal Backplane Architecture: Accepts both RX3i and legacy Series 90-30 I/O modules — protects existing infrastructure investment during system upgrades.
- High-Speed Ethernet Native: Onboard 10/100 Mbps Ethernet eliminates the need for a separate communications module, reducing BOM cost and rack space.
- Multi-Protocol Flexibility: Simultaneous support for SRTP, Modbus TCP, EGD, and OPC enables seamless integration with SCADA, HMI, and MES layers.
- Deterministic Scan Performance: Sub-millisecond boolean scan times ensure real-time response for high-speed discrete and motion control applications.
- Field-Upgradeable Firmware: Firmware updates via Ethernet without module removal — minimizes planned downtime during system maintenance windows.
- Extended Temperature Range: Rated 0–60°C for operation in non-climate-controlled industrial enclosures.
- Long Platform Lifecycle: PACSystems RX3i is GE’s strategic PLC platform with documented long-term support — reduces obsolescence risk for capital-intensive installations.
System Architecture & Signal Flow
The EPSCPE100-ABAE occupies Slot 0 of the RX3i universal backplane. The CPU communicates with all I/O and specialty modules via the high-speed VME64 backplane bus (320 MB/s), ensuring deterministic data exchange across the rack. The onboard Ethernet port connects directly to plant LAN or dedicated control network for SCADA/HMI communications. Dual RS-232 serial ports support legacy device integration (drives, instruments, barcode readers) via SNP or Modbus RTU. The CPU manages the complete program scan cycle: input scan → logic solve → output update → communications service, with configurable constant sweep or demand modes.

Technical FAQ
Q: Is the EPSCPE100-ABAE compatible with Series 90-30 I/O modules?
A: Yes. The PACSystems RX3i universal backplane accepts both RX3i-native and legacy Series 90-30 I/O modules, enabling phased migration without replacing existing field wiring.
Q: What programming software is required?
A: GE Proficy Machine Edition (PME) is the standard programming environment. The EPSCPE100-ABAE supports Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), and Instruction List (IL) per IEC 61131-3.
Q: Can this CPU be used in a redundant configuration?
A: The EPSCPE100-ABAE supports hot-standby CPU redundancy when paired with the IC695RMX128 redundancy memory xchange module and a redundant backplane configuration.
Q: What is the maximum number of I/O modules supported?
A: A single RX3i rack supports up to 12 I/O slots. With remote I/O expansion via PROFINET or Ethernet, the system scales to thousands of I/O points across distributed racks.
Q: Is firmware upgrade possible in the field?
A: Yes. Firmware can be updated via the Ethernet port using Proficy Machine Edition without removing the module from the rack, minimizing downtime.
