Description
Overview
The IC695CPU315‑BB CPU Module is a high‑performance processor designed for GE’s PACSystems RX3i automation platform. Built around a 1.0 GHz Intel Celeron M architecture, this controller delivers the computing power required for advanced machine control, large‑scale logic execution, and real‑time industrial automation tasks. Its combination of extensive memory resources and robust communication interfaces makes it suitable for complex, data‑intensive applications.
Functional Characteristics
The module provides 20 MB of user memory and an additional 20 MB of non‑volatile RAM, enabling storage of large logic programs, historical data, and system variables. It supports up to 512 program blocks, each with a capacity of 128 KB, allowing engineers to structure applications efficiently.
I/O memory allocation includes:
-
32 kilobits for discrete inputs/outputs (%I, %Q)
-
32 kilowords for analog inputs/outputs (%AI, %AQ)
The IC695CPU315‑BB communicates through two onboard serial ports supporting RS‑232 and RS‑485, with protocol options such as Modbus RTU slave, SNP, and standard serial I/O. A high‑speed PCI bus interface ensures fast data transfer when installed in compatible RX3i backplanes (IC695CHS012, IC695CHS016).
System Integration and Compatibility
A key advantage of this CPU is its backward compatibility with GE’s legacy Series 90‑30 I/O modules and expansion racks, simplifying modernization projects. Firmware can be updated in the field, extending the module’s operational life and ensuring alignment with evolving system requirements.
