GE IC695ACC400-AA CPU Energy Pack

Product Details

IC695ACC400-AA Product Description

The GE IC695ACC400-AA is a CPU Energy Pack designed for the GE PACSystems RX3i platform, providing sustained power backup to the CPU module during power interruptions and ensuring uninterrupted data retention across the automation network. In smart factory environments where continuous data flow is non-negotiable, the IC695ACC400-AA plays a critical role in maintaining the integrity of the control loop — from field-level signal acquisition through to SCADA visualization and remote diagnostics.

Within a fully connected automation architecture, the RX3i CPU — supported by the IC695ACC400-AA energy pack — serves as the central processing node for real-time data exchange between remote I/O racks, HMI terminals, EtherNet/IP-enabled drives, and upstream MES or SCADA systems. When a power transient occurs on the plant floor, the energy pack ensures that the IC695CHS016 rack backplane and all installed modules — including communication co-processors and analog I/O modules — retain their operational state without triggering a cold restart that would disrupt the data pipeline.

In a modern smart factory deployment, the GE IC695ACC400-AA underpins the reliability of the entire data chain originating from the RX3i CPU. Consider a typical architecture: field sensors and actuators feed analog and digital signals into IC694MDL660 discrete input modules and IC695ALG600 analog input modules mounted in the RX3i rack. These signals are processed by the IC695CPU315 CPU, which executes ladder logic and function block programs in real time.

The CPU communicates upstream via the IC695ETM001 EtherNet/IP communications module, transmitting process variables, alarm states, and diagnostic data to a SCADA server running GE Cimplicity or Ignition. Simultaneously, an IC695PBM300 PROFIBUS master module may be coordinating data exchange with remote variable frequency drives and smart sensors on the plant floor. An IC695CMM002 serial communications module handles legacy Modbus RTU devices — older flow meters, pressure transmitters, or barcode readers — bridging them into the EtherNet/IP backbone.

At the edge, an industrial gateway such as the IC695ETM001 or a third-party edge computing node aggregates data from multiple RX3i racks and forwards structured payloads to cloud-based MES or ERP platforms via OPC-UA or MQTT. HMI panels connected via EtherNet/IP display real-time KPIs — cycle times, energy consumption, OEE metrics — enabling operators to make data-driven decisions on the production floor.

The IC695ACC400-AA energy pack ensures that during any power disturbance — whether a momentary dip or a full outage — the CPU retains its program memory, I/O table, and communication session state. This means EtherNet/IP connections to the SCADA server are not dropped, Modbus TCP sessions with remote I/O are preserved, and alarm histories are not lost. The result is a seamless, uninterrupted data flow that supports real-time monitoring, remote diagnostics, and predictive maintenance across the entire connected factory.

Protocol Fragmentation: Many industrial sites operate a mix of EtherNet/IP, Modbus TCP, PROFIBUS, and serial Modbus RTU devices. The RX3i platform — with the IC695ACC400-AA maintaining CPU continuity — supports multi-protocol communication through dedicated co-processor modules, eliminating the need for external protocol converters and reducing latency in cross-protocol data exchange.

Data Islands and Visibility Gaps: Without a reliable CPU energy backup, unexpected restarts create gaps in historian data, break SCADA trending, and trigger false alarms. The IC695ACC400-AA prevents cold restarts, ensuring continuous data logging and uninterrupted OPC-UA data feeds to upstream analytics platforms.

Remote Monitoring and Diagnostics: The RX3i CPU, kept operational by the IC695ACC400-AA, supports remote diagnostics via EtherNet/IP and SRTP. Engineers can interrogate CPU fault tables, I/O module status, and communication health from a remote engineering workstation or SCADA client without requiring a site visit — reducing mean time to repair (MTTR) and operational downtime.

Production Line Transparency: By maintaining CPU state across power events, the IC695ACC400-AA enables continuous OEE tracking, alarm journaling, and batch record integrity — critical for regulated industries such as pharmaceuticals, food and beverage, and automotive manufacturing.

System Scalability: The RX3i platform supports expansion through additional I/O racks, remote drop modules, and communication co-processors. The IC695ACC400-AA ensures that as the system grows, the CPU remains the stable anchor of the data architecture — reliably managing increased I/O counts, additional EtherNet/IP nodes, and expanded SCADA tag databases.

Q1: Does the IC695ACC400-AA affect EtherNet/IP communication latency?The IC695ACC400-AA is a passive energy storage module that provides power backup to the CPU. It does not introduce any latency into the EtherNet/IP communication path. Network latency is determined by the IC695ETM001 communications module, switch infrastructure, and CPU scan cycle — all of which remain unaffected by the energy pack.

Q2: Is the IC695ACC400-AA compatible with all RX3i CPU variants?The IC695ACC400-AA is compatible with the IC695CPU310, IC695CPU315, and IC695CPU320 CPU modules mounted in GE PACSystems RX3i universal backplanes (IC695CHS016, IC695CHS012). It is not designed for the RX7i or RSTi-EP platforms. Always verify the CPU firmware revision against GE's compatibility matrix before installation.

Q3: How does the energy pack support remote diagnostics and SCADA integration?By preventing CPU cold restarts during power events, the IC695ACC400-AA ensures that SCADA communication sessions — whether via EtherNet/IP, Modbus TCP, or OPC-UA — remain active. This allows remote diagnostic tools and SCADA historians to maintain continuous data acquisition without session re-establishment delays or data gaps in trending records.

Q4: What warranty and pre-shipment testing does this unit include?Every IC695ACC400-AA unit supplied by NANKMOS is covered by a 12-month warranty from the date of shipment. Each unit undergoes pre-shipment functional testing to verify charge retention and compatibility with the RX3i CPU module. In-stock units are available for immediate dispatch to support urgent project timelines globally.
