GE IC695CDEM002 Retrofit-Compatible DeviceNet Master for Legacy

GE IC695CDEM002 Retrofit-Compatible DeviceNet Master for Legacy Systems

The GE IC695CDEM002 is a DeviceNet Master Communication Module designed for the GE PACSystems RX3i platform. As industrial facilities face the challenge of maintaining aging automation infrastructure, this module serves as a critical bridge between legacy DeviceNet field device networks and modern control architectures. Whether you are replacing a failed IC695CDEM002 in an existing control cabinet, migrating from an older Series 90-30 or VersaMax system, or expanding I/O capacity on an existing RX3i backplane, this module delivers the compatibility and reliability your operation demands.

NINERMAS maintains verified stock of the IC695CDEM002 with full functional testing prior to shipment and a 12-month warranty on every unit. Our team supports customers through the complete retrofit process — from pre-shipment compatibility verification to post-installation commissioning guidance.

Retrofit Planning for Existing Automation Systems

Replacing the IC695CDEM002 in a live production environment requires careful pre-planning to protect existing program logic and minimize disruption to field device communication. Before removing the existing module, engineers should export the full hardware configuration from Proficy Machine Edition and document all DeviceNet slave MAC IDs, I/O connection types (polled, change-of-state, or cyclic), and explicit messaging paths currently active on the network.

The IC695CDEM002 occupies a single universal slot on the RX3i backplane. Common backplane configurations include the IC695CHS012 (12-slot) and IC695CHS016 (16-slot) chassis. If the control cabinet also houses an IC695ETM001 Ethernet module or an IC695PBM300 PROFIBUS Master, confirm that the slot reassignment does not conflict with existing rack addressing. The IC695CPU310 or IC695CPE330 controller must have its hardware configuration updated in PME to reflect the new module slot position if the replacement unit is installed in a different slot than the original.

Power budget verification is essential. The IC695PSA040 (40W AC) or IC695PSD040 (40W DC) power supply must have sufficient headroom to support the IC695CDEM002 alongside other installed modules such as IC695ALG600 analog input modules, IC695MDL654 discrete output modules, or IC695MDL740 discrete input modules. A power budget worksheet should be completed before finalizing the retrofit plan.

For facilities migrating from older GE Series 90-30 (IC693) or VersaMax (IC200) platforms to the RX3i architecture, the IC695CDEM002 enables continuity of existing DeviceNet field device networks — including drives, valve manifolds, smart sensors, and distributed I/O blocks — without requiring replacement of field wiring or device reconfiguration. Signal isolators may be required at the trunk line interface if cable runs exceed DeviceNet distance specifications or if electrical noise is present in the control cabinet environment.

Where HMI integration is part of the retrofit scope, existing Proficy iFIX or Cimplicity screens referencing DeviceNet I/O tags should be reviewed to confirm that tag addresses remain consistent after the hardware configuration download. If the IC695CDEM002 is being added to expand an existing system rather than replace a failed unit, new I/O connection objects must be configured in PME and the updated project downloaded to the IC695CPE330 or IC695CPU310 controller during a planned maintenance window.

Downtime Control During System Migration

Minimizing unplanned downtime during an IC695CDEM002 replacement is achievable with a structured swap procedure. The recommended approach is to perform the module exchange during a scheduled maintenance window with the RX3i rack powered down. Before shutdown, place the CPU in Stop mode and force all critical outputs to their safe state through the Proficy Machine Edition online monitoring interface. Document the current I/O status and any active fault codes displayed on the IC695CPU310 or IC695CPE330 front panel.

Once the replacement IC695CDEM002 is seated in the backplane and the rack is powered on, the CPU will detect the new module and may generate a hardware mismatch fault if the slot configuration in the stored project does not match. Clear this fault by downloading the updated hardware configuration from PME. Perform a full DeviceNet network scan to verify that all slave devices — including any IC200GBI001 VersaMax remote I/O gateways or third-party DeviceNet adapters — are communicating correctly before returning the system to Run mode.

For critical processes where even brief interruptions are unacceptable, a parallel commissioning approach can be used: configure and test the replacement module in a bench environment using a spare IC695CHS012 chassis and IC695PSA040 power supply before the live swap. This allows full verification of device connections, baud rate settings, and I/O mapping without impacting production. The tested configuration file can then be downloaded to the live system during a minimal-duration maintenance window, reducing in-field commissioning time to under 30 minutes in most cases.

All IC695CDEM002 units supplied by NINERMAS are functionally tested prior to shipment, with test reports available on request. This pre-shipment verification eliminates the risk of receiving a non-functional replacement and further reduces potential downtime exposure.

Retrofit Support FAQ

Q: Is the IC695CDEM002 a direct drop-in replacement for a failed unit in my existing RX3i rack?
A: Yes. The IC695CDEM002 is a direct slot-compatible replacement for any existing IC695CDEM002 installed in an IC695CHS012 or IC695CHS016 backplane. No mechanical modifications are required. You will need to re-download the hardware configuration from Proficy Machine Edition after installation to clear any hardware mismatch faults.

Q: Will my existing DeviceNet slave devices and wiring work with the replacement module?
A: In the vast majority of cases, yes. The IC695CDEM002 supports the full DeviceNet specification at 125K, 250K, and 500K baud. Existing trunk and drop wiring, termination resistors, and slave device configurations remain valid. After installation, perform a network scan in PME to confirm all slave MAC IDs are detected and I/O connections are established correctly.

Q: What is the lead time and warranty for IC695CDEM002 units from NINERMAS?
A: NINERMAS maintains verified stock of the IC695CDEM002 for immediate shipment. All units carry a 12-month warranty covering functional defects. Pre-shipment functional testing is performed on every unit, and test documentation is available upon request. Contact our team at sale@ninermas.com or +0086 187 5021 5667 for current availability and pricing.

Q: Can the IC695CDEM002 be used to migrate a legacy Series 90-30 DeviceNet network to the RX3i platform?
A: Yes. The IC695CDEM002 is the standard DeviceNet Master module for the RX3i PACSystems platform and supports the same DeviceNet protocol used by legacy IC693 Series 90-30 systems. Field device configurations, MAC ID assignments, and network wiring can typically be preserved during the platform migration, significantly reducing retrofit scope and cost.
