IC695CRU320-EN Product Description

The GE IC695CRU320-EN is a high-performance Ethernet CPU module engineered for the PACSystems RX3i platform, purpose-built to serve as the central intelligence and network backbone of modern smart factory environments. With dual embedded Ethernet ports supporting SRTP, Modbus TCP, and EtherNet/IP simultaneously, the IC695CRU320-EN eliminates the need for separate communication co-processors and delivers deterministic, low-latency data exchange across every layer of the industrial network — from field-level sensors and remote I/O to SCADA servers, MES platforms, and cloud-based analytics systems.

In today's connected manufacturing landscape, the ability to move process data reliably and in real time is not optional — it is the foundation of operational transparency, predictive maintenance, and production efficiency. The IC695CRU320-EN is designed precisely for this role, acting as the protocol-aware hub that bridges legacy field devices with modern Ethernet-based control architectures.

The IC695CRU320-EN sits at the center of a layered industrial data architecture. At the field level, discrete and analog signals are collected through GE RX3i I/O modules such as the IC694MDL754 (discrete output) and IC695ALG600 (analog input), which feed real-time process values directly into the CPU's data tables via the high-speed RX3i backplane. These values — temperatures, pressures, flow rates, motor speeds — are immediately available for ladder logic execution and for transmission upstream over Ethernet.

For distributed control architectures, the IC695CRU320-EN communicates with remote I/O drops using EtherNet/IP, enabling plant-floor expansion without additional cabling infrastructure. Remote I/O racks equipped with IC694MDL655 or IC694ALG220 modules can be polled at deterministic scan rates, ensuring that data from geographically separated process areas arrives at the CPU with minimal latency. This is particularly valuable in large-footprint facilities such as automotive assembly lines, water treatment plants, and discrete manufacturing cells.

At the HMI and SCADA layer, the IC695CRU320-EN's native SRTP server enables direct, high-speed communication with GE's own iFIX and CIMPLICITY SCADA platforms, as well as third-party systems including Inductive Automation's Ignition and Siemens WinCC. Operators gain real-time visibility into process variables, alarm states, and production KPIs without requiring OPC middleware or protocol gateways. For facilities that do require protocol bridging — for example, connecting legacy Modbus RTU field devices to an EtherNet/IP backbone — an edge gateway such as the Moxa MGate MB3480 or ProSoft Technology MVI56E-MNET can be inserted between the field bus and the RX3i Ethernet port, with the IC695CRU320-EN acting as the Modbus TCP master.

Variable frequency drives (VFDs) on motor control circuits — such as the GE AF-600 FP or ABB ACS880 — can be integrated via Modbus TCP, delivering speed references, torque feedback, and fault codes directly into the RX3i program. This eliminates the need for dedicated drive communication modules and simplifies the control cabinet design. Similarly, smart sensors and IO-Link masters connected through an industrial Ethernet switch — such as the Hirschmann RS20 or Cisco IE-2000 — feed structured measurement data into the CPU's analog data tables, enabling closed-loop control and statistical process monitoring within a single program scan.

For remote diagnostics and predictive maintenance, the IC695CRU320-EN's embedded web server provides fault table access, CPU status, and I/O module health data through any standard browser on the plant network. Maintenance engineers can interrogate the controller from the control room or remotely via VPN without interrupting production. When integrated with a data historian such as OSIsoft PI or GE Historian, the IC695CRU320-EN continuously streams tagged process data for trend analysis, OEE calculation, and anomaly detection — forming the data backbone of a fully transparent smart factory.

Many industrial sites operate with a fragmented control architecture: legacy PLCs running proprietary protocols, isolated HMI islands with no historian connection, and field devices that have never been integrated into a plant-wide network. The IC695CRU320-EN directly addresses these data gaps through its multi-protocol Ethernet stack and open communication architecture.

Protocol Fragmentation: Sites running a mix of Modbus RTU, DeviceNet, and Profibus devices can consolidate data flows through the IC695CRU320-EN by using protocol gateways at the field level and presenting a unified Modbus TCP or EtherNet/IP interface to the SCADA layer. This eliminates the need for multiple OPC servers and reduces configuration complexity.

Data Silos: When production data is trapped in standalone controllers with no network connectivity, the IC695CRU320-EN's peer-to-peer SRTP communication allows RX3i controllers across multiple production lines to share data tables directly — without routing through a central server. This enables cross-line interlocking, coordinated batch control, and plant-wide alarm management.

Remote Monitoring Gaps: For facilities without on-site engineering staff, the IC695CRU320-EN's web-based diagnostics and SNTP time synchronization ensure that fault events are timestamped accurately and accessible remotely. Combined with a cellular or fiber-connected edge gateway, remote engineers can perform fault analysis, program uploads, and parameter adjustments without travel.

Production Transparency: By connecting the IC695CRU320-EN to a SCADA or MES platform, production managers gain real-time dashboards showing cycle times, reject rates, energy consumption, and equipment availability — transforming raw PLC data into actionable business intelligence.

System Scalability: The RX3i platform's modular architecture means that as production capacity grows, additional I/O modules, communication modules, and remote drops can be added without replacing the CPU. The IC695CRU320-EN supports up to 512 KB of user program memory and handles complex motion, process, and discrete control tasks within a single controller.

Q1: What communication protocols does the IC695CRU320-EN support natively?The IC695CRU320-EN supports SRTP (Service Request Transport Protocol), Modbus TCP (client and server), EtherNet/IP (adapter mode), SNTP for time synchronization, FTP for program file transfer, and HTTP for web-based diagnostics — all over its dual embedded Ethernet ports without requiring additional communication modules.

Q2: Can the IC695CRU320-EN communicate with third-party SCADA and HMI systems?Yes. The IC695CRU320-EN is compatible with any SCADA or HMI platform that supports SRTP, Modbus TCP, or EtherNet/IP, including Inductive Automation Ignition, Siemens WinCC, Wonderware System Platform, and Kepware KEPServerEX via OPC-DA/UA drivers. Native drivers are available for GE iFIX and CIMPLICITY without additional licensing.

Q3: How is network stability and communication latency managed in large plant networks?The IC695CRU320-EN supports configurable Ethernet channel parameters including timeout values, retry counts, and producer/consumer connection rates for EtherNet/IP. For network-level stability, it is recommended to deploy managed industrial Ethernet switches with IGMP snooping and QoS prioritization to ensure PLC traffic is not starved by bulk data transfers. VLAN segmentation between control and information networks further reduces latency and improves determinism.

Q4: What warranty and pre-shipment testing does NANKMOS provide for the IC695CRU320-EN?Every IC695CRU320-EN unit supplied by NANKMOS carries a 12-month warranty covering hardware defects and communication failures under normal operating conditions. Each unit undergoes pre-shipment functional testing including power-on verification, Ethernet port connectivity check, and firmware version confirmation before dispatch. Units are available from in-stock inventory and ship worldwide with full documentation support.
